The best joist hangers, compared.
Top pick: BPC mini joist hangers, 47 mm, 10-piece – Highest score at 84: a 47 mm mini for timber up to 100 mm, 4.6 from 145 ratings, at about £9.70. Not a lab test. Best value: FIXINGS DIRECT mini hangers, 50 mm, 10-piece – About £8.99 for ten, score 75 and 4.5 from 542 ratings, when the timber is about 50 mm. Updated 23 October 2026.
A joist hanger is a steel connector that seats the end of a timber joist or trimmer on a supporting timber or, in other ranges, on masonry. In the UK you use one on regularised carcassing, a ceiling hatch or a small deck, so measure the timber's real width and depth first. A usable listing states the seat width, the depth class, the coating and the nail the hanger was tested with. Regularised 47 by 100 mm C16 often finishes nearer 45 by 95 mm. A 47 mm seat is the usual trade fit for that timber. A 50 mm seat leaves a gap. Mini hangers are the short, light pattern for timber up to about 100 mm, including a hatch. A standard leg is the longer strap, for about 150 to 250 mm. Z275 is the usual internal zinc, for service classes 1 and 2. A wet deck is service class 3 and needs a heavier coating or stainless steel, with matching nails. Width, depth and the nail are set out in the [joist hanger buying guide](/hub/diy-supplies/joist-hanger/sub/joist-hanger-buying-guide).

Question 1 of 2
How deep is the joist?
The BPC Fixings MINI/47/10PK is a 10-piece galvanised mini hanger with a 47 mm seat, listed at £9.70, and the bullet limits the timber to 100 mm, including a ceiling hatch. Across 145 amazon.co.uk ratings the line is 4.6, and one UK review says that 47 mm width was exact. Reviewers describe decks, joists into wall plates, a cabin roof, and a solar canopy, and they mention plenty of holes. The same page prints 0.8 mm in the bullet and 0.9 mm in the item-depth field, and the material field says alloy steel, so the thickness is not a single declaration. Nails are not in the included line. Two UK reviews were short: 8 of 10 in one box, and a single bracket in another. Edges are sharp enough that a review tells you to wear gloves. It is the top pick here for a shallow regularised joist or a hatch trim, and it is the wrong hanger if the joist is 150 mm or deeper.
Pros
Cons
Best for: You are trimming a ceiling hatch or seating regularised timber near 45 mm wide and no deeper than 100 mm, and you will buy the square-twist nails separately and count the box.
Less suitable: A joist in the 150 to 250 mm band, a sawn 50 mm seat, or a wet deck that needs a declared service class 3 hanger.
Specifications
Common questions
What timber width is this 10-piece for?
The title says 47 mm. One UK review says that width was exact. The bullet limits timber depth to 100 mm and names ceiling hatches.
Are nails in the box?
No. Included components name the 10-piece set only. Two UK reviews were also short: 8 of 10 in one box, and a single bracket in another.
How thick is the steel?
The bullet says 0.8 mm galvanised steel. The item-depth field says 0.9 mm, and the material field says alloy steel.
The BPC MINI/47/TRADE is the 50-piece mini at 47 mm, £28.69, and the bullet says 0.9 mm galvanised steel for timber up to 100 mm, including ceiling hatches. Across 132 amazon.co.uk ratings the line is 4.6. UK reviews describe ground-level decks, a car port with noggins, a shed base, a cabin, and a garden-office floor, and one says the steel was pliable enough to butt tight at T joints. A box arrived with about half the quantity, and that review said there was no return option. Nails are not listed. This bullet says 0.9 mm while the 10-piece sibling bullet says 0.8 mm, so the family thickness is not one number. On a full count the title price is about £0.57 each, which only holds if you actually receive 50. It suits a hatch or a shallow deck frame once you have counted the hangers, and it is still a mini, not a 150 mm leg.
Pros
Cons
Best for: You need a lot of 47 mm minis for hatches or joists no deeper than 100 mm, and you will count them on arrival.
Less suitable: A joist of 150 to 250 mm, or an order you cannot open and count before the return window closes.
Specifications
Common questions
Is this the same mini as the 10-piece?
Both titles are BPC galvanised mini hangers at 47 mm for timber up to 100 mm. This bullet says 0.9 mm. The 10-piece bullet says 0.8 mm. The model here is MINI/47/TRADE.
Did buyers get 50?
The title says 50. One UK review received a box with only half the quantity and said there was no return option.
What did UK reviews build?
Ground-level decks, a car port with noggins, a shed base, a cabin and a garden-office floor. Nails are not in the included line.
Xingwenhao’s four-pack is a black type-B U, model 016, at £8.99, and the bullet prints an inner size of 46 x 91 mm in 1.9 mm steel. Across 106 amazon.co.uk ratings the line is 4.6. UK reviews use them on a garden fence, as rafter hangers between a ledger and a fascia, as bed supports, and for metal bars on a gate. One UK review measured about 50 mm inside and 54 mm outside, and said a 2x4 was marginally too big and rocked because there were no side holes. The colour field reads Schwarz, the material bullet says Q235 iron, and the material field says carbon steel, with no zinc mass. Screws are not in the pack. The bullet says indoor and outdoor use, which is not a service class. Treat it as a short concealed-flange connector for a light beam, and leave it when you need a 47 mm timber-to-timber hanger with side nailing.
Pros
Cons
Best for: You want a short black U for a light fence rail, a gate bar, or a small rafter, and you will measure the inside width before the timber is cut.
Less suitable: A 47 mm joist that must be nailed through both sides, or a wet deck that needs stainless steel or a declared service class 3 coating.
Specifications
Common questions
Will a 2x4 sit tight?
The bullet says an inner size of 46 x 91 mm. One UK review measured about 50 mm inside and said a 2x4 rocks because there are no side holes.
Are these for a wet deck?
The bullet says indoor and outdoor use, and UK reviews include a fence and rafters. It does not name a zinc mass, stainless steel, or a service class.
Do screws come with the four-pack?
The page asks and does not answer. The bullets tell you to use wood screws or hardened nails. They are not in the included list.
LLB’s listing is a pack of five 2.0 mm hangers with a 30 mm seat, galvanised Z275 at 275 g/m², priced at £19.99. The highlight prints 16.97 kN and equates it to 1,730 kg, with no test method or nailing schedule on the page, so that figure is not a safe working load. Across 81 amazon.co.uk ratings the line is 4.6. UK reviews mention shelving, a pergola, and oversized joists, and one liked the range of holes: 32 at 5 mm and four at 11 mm. One UK review says a set is a left-hand hanger and a right-hand hanger, which the title does not spell out. The seat is 30 mm, so it does not replace a 47 mm or 50 mm hanger. Nails and bolts are not listed. The outdoor question is unanswered even though the highlight names decking. Use it only when 30 mm is the width you measured, and do not read 1,730 kg as the capacity of a floor.
Pros
Cons
Best for: You have measured a 30 mm member and you want thicker Z275 steel than a mini, with the pair count checked before you pay.
Less suitable: Regularised 47 mm joists, a ceiling hatch, or anyone treating 1,730 kg as a floor load.
Specifications
Common questions
Does 30 mm fit a 47 mm joist?
The size bullet is 30 mm wide. That is narrower than the 47 mm and 50 mm hangers in this set. One UK review calls them hangers for oversized joists, without giving a timber size.
Is 1,730 kg a safe working load?
The listing prints 16.97 kN and equates it to 1,730 kg and 3,813 lb. No standard or nailing schedule is on the page.
How many hangers are in five sets?
The title says a pack of 5 and the fields say 5 items. One UK review says one set is a left-hand hanger and a right-hand hanger, and that the advert did not make this clear.
FIXINGS DIRECT’s multi-truss hanger is titled as a pack of 20 at 47 mm, in 2 mm galvanised steel, for joists up to 6x2, at £50.99. The unit-count field says 5 and the included-components line says Case, so you should not divide £50.99 by 20 or by 5. The size bullet is 47 mm or 50 mm by 150 mm by 75 mm, which is not the same as a standard leg for 150 to 250 mm timber. Across 31 amazon.co.uk ratings the line is 4.6. UK reviews mention a pergola with hanging seats and decking support, and one buyer chose the thicker metal because it would sit in the weather. The bullet names 3.75 mm twist nails or 12 mm anchor bolts, and they are not in the pack. One UK review used different holes each side so the fixings did not meet inside the timber, and another would not comment on rust. The weather-and-UV line is a bullet, not a service class.
Pros
Cons
Best for: You want a thicker 47 mm multi-truss hanger than a 0.9 mm leg, and you will confirm how many pieces are in the carton before you rely on a unit price.
Less suitable: A ceiling hatch, a counted 50-piece mini, or a wet joint that needs a declared service class rather than a weather bullet.
Specifications
Common questions
How many are in the pack?
The title says a pack of 20 at 47 mm. The unit-count field says 5. Included components say Case. Do not divide £50.99 by either number.
Will this take a 6x2?
The bullet says joists up to 6x2, heavy decks, trusses and purlins, at 2 mm, with nail holes and bolt holes. No kilonewton figure is printed.
Is galvanised here a wet-deck rating?
The bullet says full weather and UV resistance. It does not name Z275, stainless steel, or a service class. One UK review still would not comment on rust.
FIXINGS DIRECT’s 10-piece mini is titled 50 mm, or 2 inch, timber to timber, at £8.99. The star line is 4.5 from 542 ratings, the largest sample in this set, and UK reviews describe deck joists, a log-cabin floor, a false ceiling, garage joists, and a mezzanine on 4x2 beams. Thickness, coating weight, and timber depth are not printed. The finish field says polished and the colour is silver, which is not the same as a zinc mass. One UK review counts 16 holes and says they were small for the screws they wanted. Another says the hangers bend easily and will not support a decent weight. Nails are not listed, and the outdoor question is unanswered even though reviews mention decks. It is the best value here when your timber is actually about 50 mm and the job is light, and it is a poor match for regularised stock near 45 mm.
Pros
Cons
Best for: You have sawn timber about 50 mm wide, you want a cheap mini ten-pack with a large review sample, and you will check the holes before you commit to screws.
Less suitable: Regularised carcassing near 45 mm, a deep joist, or any joint where you need a printed thickness and a named nail.
Specifications
Common questions
Is 50 mm the same as a regularised joist?
The title is 50 mm, or 2 inch. It does not say 47 mm. UK reviews used these on 2x4 deck joists and on 4x2 mezzanine beams.
Does the listing say galvanised?
No. Thickness and coating are blank. The finish field says polished and the colour is silver.
Are the holes ready for screws?
The listing does not give a hole size. UK reviews say the holes were small, and some people opened them. One review says the hangers bend easily and will not hold a decent weight.
AB Tools lists 20 mini hangers, model FN051_20PK, at £16.91, with 47 mm in the title and 4.7 cm in the dimensions. The bullet says 0.9 mm galvanised steel and timber up to 100 mm, including ceiling hatches, and the title also says decking and loft. The star line is 4.5 from only two ratings, and the saved listing has no review text, so nobody in this capture describes a fit, an edge, or a count. A separate item-depth field says 38 mm, which does not match 47 mm. The material field says alloy steel, and no zinc mass is printed. Nails are not listed. The outdoor question is unanswered. On the title count the pack is about £0.85 each, but two silent ratings are too thin to treat this as a checked 47 mm mini.
Pros
Cons
Best for: You already know this model from a trade counter and you only need the amazon.co.uk price and the printed 47 mm title checked against your timber.
Less suitable: A first order where you want UK review notes on fit, edges, or whether all 20 arrived.
Specifications
Common questions
Is the seat 47 mm or 38 mm?
The title says 47 mm, and the dimensions include 4.7 cm. A separate item-depth field says 38 mm. There is no review text to settle it.
What are they for?
The bullet says timber up to 100 mm and ceiling hatches. The title also says decking and loft. Nails are not listed in the pack.
What do the two ratings say?
The star line is 4.5 from 2. The saved listing has no review text, so fit, edges and count are unknown.
BPC’s A270/47/TRADE is a 50-piece standard-leg hanger at 47 mm and £41.95, and the bullet says 0.9 mm galvanised steel for joist depths of 150 to 250 mm. The listing says the leg can be wrapped over to suit the joist height, which is the only wrap sentence in this eight-row set. Across 47 amazon.co.uk ratings the line is 4.4. Two UK reviews call the steel thin and say a lot of fixings are required, and one box arrived as 49. Nails are not listed, and there is no load figure and no zinc mass. The strap is described as a wider 50 mm leg. The outdoor question on the page is unanswered. It is the row to open when the joist is actually in that 150 to 250 mm band, and wrapping a mini because this page allows a wrap is not what the bullet says.
Pros
Cons
Best for: You are face-fixing or wrapping a 47 mm joist between 150 and 250 mm deep, using the nail that sheet names, and you will count to 50.
Less suitable: A hatch or a joist under 100 mm, where a mini is the depth class, or a wet deck with no service class on the page.
Specifications
Common questions
When is a standard leg the one to use?
This listing is for joist depths of 150 to 250 mm, with 50 mm strap legs. The mini listings in this set stop at 100 mm.
Can the leg be bent over the joist?
The bullet says it can be adjusted by wrapping it over to suit the joist height. The page does not give a bend limit.
Are all 50 in the box?
The title says 50. One UK review received 49. Two UK reviews call the steel thin and say a lot of fixings are required. Nails are not listed.
Eight amazon.co.uk listings were scored on 21 October 2026. Four further listings in the queue had no saved listing and were not scored. There is no pull-out test, no zinc-thickness check and no count of a fresh delivery. Each score adds the star line, the review sample, listing clarity, UK review notes and whether a maker and a model code are printed. The highest score is the top pick. Best value is separate: the lowest shelf price in this set, tied with one other row, on the largest review sample. A printed kilonewton with no method is not added. Non-UK review text is not British opinion. None of these packs is scored as UKCA marked, BS EN 845 compliant or Building Regulations approved.
Star line
37%The amazon.co.uk star line is multiplied by eight and rounded. A 4.6 becomes 37, a 4.5 becomes 36, and a 4.4 becomes 35. Stars are not the whole score.
Review sample
17%The amazon.co.uk count adds 18 from 500 ratings upward, 14 from 100 to 499, 10 from 40 to 99, 6 from 20 to 39, and 2 below 20. A thin sample cannot match a larger one on stars alone.
Listing clarity
32%Seat width, depth class, thickness, coating, fixings and pack count are marked from what the page prints. A second width, a blank thickness or a count a UK review contradicts scores lower. The marks are added up and not capped.
UK review notes
11%A UK job and a UK fault start at 10. A short box, a hanger that bends, or a measurement that disagrees is deducted. A UK note that the printed seat was exact adds a mark. The block is capped at 12.
Printed identity
3%Three points when the manufacturer and a model code are both printed, one point when only one of those is printed, and none when neither is printed.
You are matching a steel connector to a measured joist. The eight amazon.co.uk listings here are 47 mm and 50 mm minis, a standard leg for 150 to 250 mm, a 30 mm set, a black type-B four-pack and a 2 mm multi-truss hanger. Shelf prices run from about £8.99 to about £50.99. The top pick is the BPC Fixings 47 mm mini ten-piece at about £9.70, score 84, for timber up to 100 mm.
A joist hanger is a steel connector. It seats the end of a timber joist or trimmer on a supporting timber. Other ranges seat a joist on masonry. UK shoppers meet them on regularised carcassing, around a ceiling hatch, or under a small deck. The hanger is not the joist, and it is not a post cap, a hurricane clip or an angle bracket. Those are different products. You recognise a usable one by four printed facts: the seat width, the depth class, the coating, and the nail it was tested with.
Regularised 47 by 100 mm C16 often finishes nearer 45 by 95 mm. A 50 mm seat leaves a gap. Measure after the timber is regularised, not from the nominal size on the joist stamp.
Minis in this set stop at about 100 mm. The standard leg covers 150 to 250 mm, and it is the only listing that says the strap can wrap. Do not bend a mini to copy that sentence.
The tested fixing for this kind of mini is a square-twist nail, about 30 or 35 by 3.75 mm, not an ordinary woodscrew. Nails are not in these boxes. UK reviews record 49 of 50, 8 of 10, and one box at about half the quantity.
Seat width is the first match. A 47 mm hanger fits regularised joists that finish around 45 mm. A 50 mm hanger fits sawn 50 mm, and it leaves a gap on regularised stock. A 30 mm seat does not stand in for either. One type-B listing prints an inner size of 46 by 91 mm, and a UK review measured about 50 mm inside, so measure the inside of a U before the timber is cut. Depth class is the next match. A mini is for timber up to about 100 mm, which covers a hatch and a shallow joist.
Thickness tells you the duty. Mini pages in this set print about 0.8 mm or 0.9 mm, and those two figures do not always agree inside one family, so treat a mini as light-duty. The multi-truss listing and the 30 mm set print 2.0 mm. The type-B listing prints 1.9 mm. Thicker steel is not a wider seat. Z275, at 275 g/m², is the usual internal zinc and is associated with service classes 1 and 2. A wet deck is service class 3 and needs heavier zinc or stainless steel, and nails to match.
Three typical situations, each with a recommendation from this comparison.
You are trimming a ceiling hatch or seating regularised timber near 45 mm wide and no deeper than 100 mm. The top pick is the BPC mini ten-piece at about £9.70, score 84, 4.6 from 145 ratings. Buy the square-twist nails separately and count the box. It is the wrong hanger for a 150 to 250 mm joist.
You have sawn timber about 50 mm wide and you want a cheap mini ten-pack with a large review sample. Best value is the FIXINGS DIRECT ten-piece at about £8.99, score 75, 4.5 from 542 ratings. Thickness and coating are not printed. It is a poor match for regularised stock near 45 mm.
The joist is 47 mm wide and between 150 and 250 mm deep. The BPC standard-leg fifty-pack at about £41.95 is the only row in that depth band, score 79, 4.4 from 47 ratings. The bullet says the leg can wrap. Count to 50, and do not use it as a service class 3 hanger.
The top pick is the BPC mini joist hangers, 47 mm, 10-piece, at about £9.70. It scores 84, the highest in this set: 4.6 from 145 amazon.co.uk ratings, a UK review that the width was exact, and a bullet that limits timber to 100 mm. It is not a lab test. The page prints both 0.8 mm and 0.9 mm, and two UK reviews were short. Skip it for a 150 to 250 mm joist, for sawn 50 mm timber, or for a wet deck that needs a declared service class 3 hanger. Best value is the FIXINGS DIRECT mini hangers, 50 mm, 10-piece, at about £8.99, score 75, 4.5 from 542 ratings. That is the joint-lowest shelf price and the largest review sample. Thickness is blank, so skip it when the timber is regularised near 45 mm.
BPC mini joist hangers, 47 mm, 10-piece
Highest score at 84: a 47 mm mini for timber up to 100 mm, 4.6 from 145 ratings, at about £9.70. Not a lab test.
FIXINGS DIRECT mini hangers, 50 mm, 10-piece
About £8.99 for ten, score 75 and 4.5 from 542 ratings, when the timber is about 50 mm.
