The best aircrete fixings, compared.
Top pick: Corefix 100 mm (24) – Highest score: 4.7 from 1,437 ratings, a UK-made 24-pack, and bullets that name aerated and lightweight block as well as dot-and-dab. Best value: Corefix 100 mm (4) – Highest value part: about £6.30 and 4.6 from 1,454 ratings, for one flush job on plasterboard over block. Updated October 2026.
Aircrete fixings are anchors and screws for aerated concrete blocks and for plasterboard stuck to lightweight block with dabs of adhesive. UK houses use that soft block on internal leaves and in garages. A standard wall plug spreads load into a small cone. In soft block that cone crushes the face, so the fixing has to cut into the block or bridge the cavity to the masonry behind the board. Tell the two walls apart before you buy. Bare block needs a spiral or a metal aircrete anchor. Dot-and-dab needs a cavity-bridging fixing long enough to reach the block, a stated drill diameter, and a hole with the dust removed. Use the listing load per fixing point as a ceiling, and leave a cantilever television arm off the wall unless that listing allows it. A boiler, an external wall, or a load that could injure someone needs a builder, not a DIY anchor rating. How wall type changes the packet is set out in the [aircrete fixings buying guide](/hub/screws-and-accessories/aircrete-fixings/sub/aircrete-fixings-buying-guide).

Question 1 of 2
What is the wall?
The Corefix 100 mm 24-box, model CFX024, is £21.00 and made in the United Kingdom, with 4.7 from 1,437 amazon.co.uk ratings. Bullets name brick, stone and blockwork, including aerated and lightweight block, and they state 55 kg per fixing plus a 100 kg line when four fixings share the load. UK reviews mention Thermalite, dry-lined walls, heavy shelves and televisions. Depth is the limit: a hole that stops short wastes a plug, and the box does not include a 10 mm bit. Those kilogram lines are the seller's wording, not a pull-out measured for this page, and a cantilever bracket is outside the job the family describes. It is the top pick when you have several dot-and-dab jobs and want spare fixings of the same length. One bracket does not need 24 pieces.
Pros
Cons
Best for: Several dabbed rooms, including lightweight block, where you want spare 100 mm fixings.
Less suitable: A single bracket, a cantilever television arm, or bare block with no plasterboard.
Specifications
Common questions
What wall is this for?
Dot-and-dab and lightweight block, including aerated block named on the bullets. It bridges plasterboard. It is not a plug for bare block with no board.
Is a drill bit included?
No. You supply a 10 mm masonry bit and drill to the depth the fixing needs.
Can I use this on dot-and-dab?
Yes. This is a dot-and-dab bridging fixing. A cantilever television arm is outside the job the listing describes.
The grey fischer GB 8 wallplug, model 50491, is a 25-piece spiral set at £18.60, with 4.7 from 687 amazon.co.uk ratings. UK reviewers describe it working in porous workshop walls and as a large, sturdy plug in soft block. The fastener field is M8 / GB 8, and the tool line is a hammer, with no special setting tool. Façade use on the bullets depends on an approved fischer A4 screw, and that screw is not in the box. Shoppers mix this grey plug up with the green renewable-content carton. The UK sample does not record a repeated breakage theme. It still will not bridge plasterboard.
Pros
Cons
Best for: Bare aerated block, including a façade only when you buy the A4 screw separately.
Less suitable: Dot-and-dab cavities, or a buyer who expects the stainless screw in the packet.
Specifications
Common questions
What wall is this for?
Bare aerated or porous concrete. Façade use on the bullets needs an approved A4 screw, and that screw is not in the box.
Is a drill bit included?
No. You pre-drill, then hammer the spiral. See the pack contents on amazon.co.uk.
Can I use this on dot-and-dab?
No. This hammer-in spiral targets bare aerated block. It does not bridge plasterboard over a cavity.
The fischer GB Green box is twenty 8 mm by 50 mm hammer-in spiral anchors at £8.49, with 4.7 from 75 amazon.co.uk ratings. You pre-drill, then hammer the spiral into bare aerated or porous concrete, and the box does not include a drill bit. Only four UK review texts sit behind that star line. Those texts describe heavy e-bikes held on thermobloc garage walls, and they also say hard hammering can loosen the blocks or chip an edge. Once the anchor is in, the same notes say it is not designed to come out. Country of origin on the listing is Germany. It suits a modest load in block you can see, and it does not bridge a plasterboard cavity.
Pros
Cons
Best for: A mailbox, rail or similar modest load in bare aerated block you can see.
Less suitable: Dot-and-dab plasterboard, or a hole you may need to reuse.
Specifications
Common questions
What wall is this for?
Bare aerated or porous concrete. The listing names that substrate. It does not bridge a plasterboard cavity.
Is a drill bit included?
No. You pre-drill, then hammer the spiral in. There is no special setting tool.
Can I use this on dot-and-dab?
No. This hammer-in spiral targets bare aerated block. Use a bridging fixing where plasterboard stands off the block.
This listing is two boxes of the same fischer GB Green 8 mm by 50 mm anchor, forty pieces at £16.98. The star line stays 4.7 from 75 ratings, shared with the single 20-pack rather than a separate sample of the twin carton. You still hammer the spiral into bare aerated concrete after a pre-drill, and the UK notes on that shared line describe a hold on thermobloc garage walls. Hard hammering can shift the blocks, and the anchors are not removable. Ordering this row beside the 20-pack does not add a new design. It is the quantity choice when you will fit about forty spirals. One small job, or any plasterboard cavity, is the wrong use.
Pros
Cons
Best for: A repeat job in bare aerated block that will use about forty spirals.
Less suitable: One small job, or a dot-and-dab wall.
Specifications
Common questions
What wall is this for?
Bare aerated or porous concrete, the same spiral as the 20-pack. Forty pieces is two of those boxes, not a different anchor.
Is a drill bit included?
No. You pre-drill, then hammer. The 4.7 from 75 ratings is the single-box review line.
Can I use this on dot-and-dab?
No. This hammer-in spiral targets bare aerated block. It does not bridge plasterboard.
Corefix Connect 100 mm in a four-pack is £6.30, made in the United Kingdom, model CFX004, with 4.6 from 1,454 amazon.co.uk ratings. The highlight states 55 kg per fixing on plasterboard over block, and the listing says a cantilever television bracket is not recommended. UK reviews describe televisions and other heavy items on dot-and-dab when the 10 mm hole is clean, including soft block if you drill with care. Dust left in the hole is the repeated failure: the plug crushes. Four pieces cover one bracket and leave almost no spare, and there is no drill bit. It is the best value here for one dabbed radiator, shelf or flush screen. A stock-up, a cantilever arm, or bare block with no cavity is a poor match.
Pros
Cons
Best for: One flush television, radiator or shelf on plasterboard over block.
Less suitable: A cantilever arm, a multi-room stock-up, or bare aerated block with no board.
Specifications
Common questions
What wall is this for?
Plasterboard over block. It is a bridging fixing for one dabbed job, not a spiral for bare aerated block.
Is a drill bit included?
No. The hole is 10 mm, and you supply the masonry bit.
Can I use this on dot-and-dab?
Yes. This is a dot-and-dab bridging fixing. Clear the dust, or the plug crushes. A cantilever bracket is not recommended.
Corefix's television six-pack, model CFX006TV, is £9.49 and made in the United Kingdom, with 4.6 from 1,035 amazon.co.uk ratings. You get six 100 mm steel-core fixings and a 10 mm masonry bit, which the other Corefix boxes here do not include. The highlight states 150 kg across six fixings and also 55 kg per fixing. UK reviews praise television mounting on dot-and-dab and the kit that arrives with the bit. Hole depth and dust still decide whether the plug seats, and the listing does not recommend a cantilever bracket. A flat mount often uses four holes, so two of the six are spare rather than a load you should add on. It suits a flush screen when you do not already own a 10 mm bit. A thick bracket that needs the 120 mm screw, or bare aerated block, is a different packet.
Pros
Cons
Best for: A flush television on plasterboard over block when you want the 10 mm bit in the packet.
Less suitable: A cantilever arm, a thick bracket, or bare aerated block.
Specifications
Common questions
What wall is this for?
Plasterboard over block, sold as a television kit. It does not suit bare aerated block with no board.
Is a drill bit included?
Yes. This pack includes a 10 mm masonry bit. The other Corefix boxes in this set do not.
Can I use this on dot-and-dab?
Yes. This is a dot-and-dab bridging fixing for a flush screen. The listing does not recommend a cantilever bracket.
The Corefix 120 mm 24-box is £22.00, made in the United Kingdom, with 4.6 from 507 amazon.co.uk ratings. The longer screw is for a thick bracket or a deeper dab build-up: the bullets ask for a 120 mm hole with a 10 mm bit, and that bit is not in the box. UK reviews mention heavy glass shelves on dot-and-dab, and they also describe a weak flange if you force the plug and a broken plug when the hole is dirty. Aligning a thick bracket with those 10 mm holes is part of the skill the notes record. Extra length does nothing for a thin flush plate that the 100 mm screw already reaches. Buy it when the shorter screw would stop in the cavity or the bracket. Leave it when four 100 mm fixings would finish the job.
Pros
Cons
Best for: A thick bracket or deep dab cavity where a 100 mm screw comes up short.
Less suitable: A thin flush plate, or a job that only needs four fixings.
Specifications
Common questions
What wall is this for?
Dot-and-dab and lightweight block, when a 100 mm screw would stop in the cavity or in a thick bracket.
Is a drill bit included?
No. The bullets ask for a 120 mm hole with a 10 mm bit, and you supply that bit.
Can I use this on dot-and-dab?
Yes. This is a longer dot-and-dab bridging fixing. A dirty hole or a forced plug is the failure the UK notes describe.
Rigifix M8 is four sleeve-and-screw fixings at £8.99, with 4.6 from 242 amazon.co.uk ratings and about 50 UK review texts. The listing field states 280 kg maximum shear, which is the seller's figure, and the bullets name breeze block, Thermalite, brick and concrete. UK reviewers describe a solid floating television on dot-and-dab and a bridge that holds in some workshop aerated walls. They also say it is not a beginner job: you need an accurate 16 mm hole, the strength to wind the sleeve, and a hex key that can cope with a loose hex head. Overtightening with a power tool binds the sleeve. One reviewer points a medium radiator toward Corefix instead. Use it when the load sits in shear and you will tighten by hand.
Pros
Cons
Best for: A heavy unit held in shear on dot-and-dab or Thermalite, tightened by hand.
Less suitable: A first DIY hook, a power-tool install, or a medium radiator that Corefix already covers.
Specifications
Common questions
What wall is this for?
Dot-and-dab and aerated block, including Thermalite and breeze block on the bullets. The 280 kg line is a listing shear figure, not a test on this page.
Is a drill bit included?
No. You need an accurate 16 mm hole, then wind the sleeve by hand.
Can I use this on dot-and-dab?
Yes. The listing positions this sleeve for dot-and-dab and aerated block. Tighten by hand. A power tool can bind the sleeve.
Fischer DDF is a 50-pack of 10 by 100 mm two-component dot-and-dab fixings with matched screws, model 575286, at £38.99. The line is 4.6 from 148 amazon.co.uk ratings, with about 45 UK review notes. Reviewers describe secure television and shelf mounting on dab walls and treat the quantity as useful on a renovation. The listing uses heavy-duty plasterboard wording and does not print a kilogram you can divide the way the Corefix highlights do. Instruction clarity varies in the UK notes, and no strong repeated defect is recorded. There is no drill bit, and country of origin is Germany. Fifty pieces is a van or a whole house, not one bracket. It bridges plasterboard over masonry, and it is neither the hammer-in spiral for bare block nor a stud-wall plug.
Pros
Cons
Best for: A renovation, or van stock, of dabbed rooms that need matched screws.
Less suitable: One bracket, bare aerated block, or a stud wall.
Specifications
Common questions
What wall is this for?
A plasterboard cavity over masonry. It is a two-part dab fixing with matched screws, not a hammer-in spiral for bare block.
Is a drill bit included?
No. You drill and drive the matched screws. The listing does not print a kilogram table.
Can I use this on dot-and-dab?
Yes. This is a dot-and-dab bridging fixing. Fifty pieces is a renovation quantity, not one bracket.
The fischer FPX M10 box is 25 metal expansion anchors for bare aerated concrete at £92.40, listed at about 1.17 kg with a stainless-steel exterior finish. Stars are 4.4 from 20 ratings, and the stored notes have no UK-dated review text, so there is no praise or complaint to quote. Bullets call it an approved metal anchor for aerated concrete, with automatic set control and an expansion sleeve. The comparison fields give no household kilogram and no drill bit. A single mailbox is an expensive way to open a 25-piece trade box. It belongs where you will set metal anchors repeatedly in bare block and follow the FPX method rather than a hammer. It does not cross plasterboard.
Pros
Cons
Best for: Repeated higher loads in bare aerated concrete, set with the FPX method.
Less suitable: A first mailbox, a dabbed wall, or a buyer who wants UK review text before ordering.
Specifications
Common questions
What wall is this for?
Bare aerated concrete. Bullets call it a metal anchor with an expansion sleeve and automatic set control. There is no household kilogram on the card.
Is a drill bit included?
No. Follow the FPX setting method. The stored notes have stars from 20 ratings and no UK review text.
Can I use this on dot-and-dab?
No. This metal expansion anchor is for bare aerated concrete. It does not cross plasterboard.
Ten amazon.co.uk listings were scored from the stored pages and the UK review notes already collected. Shelf prices are the October 2026 listings. Products Compared did not run a pull-out test. Stars, review sample, review themes, wall-and-pack match and shelf value make up the score. A deduction of up to 8 points covers a shared review line, no UK review text, block damage, crushed plugs, a binding sleeve, or a cantilever ban on a television kit. The highest total is the top pick, once. The highest value part that is not the top pick is best value, once. The weights below sum to 100.
Amazon stars
25%The amazon.co.uk star line, scored as rating divided by 5, then scaled into this weight. Stars are the listing average. They are not a pull-out test.
Review sample
24%A larger review count scores higher: 1,000 or more at the top of this weight, then 500, 200, 100, 50 and 20, with under 20 at the bottom. A thin sample cannot show how the fixing behaves in block.
Review themes
20%Specific UK praise with a named limit scores in the mid-range of this weight. No UK review text scores low. Themes cover hold on dabbed walls or thermobloc, and the failures the notes repeat.
Wall and pack match
16%The listing names a wall this comparison covers, bare aerated block or plasterboard over block, and a usable pack. A drill bit or matched screws can add a point. A four-pack or a television-only kit scores lower than a box you can finish several rooms with.
Shelf value
15%A low shelf price plus a large review count scores highest. A cheap unit price with a shared or thin review line scores less. A trade box near £90 with a small review count scores low. Best value is the highest value part that is not the top pick.
Match the wall first, then the load per fixing point, then the way the anchor goes in. A hammer-in spiral, a metal expansion anchor and a cavity bridge are different jobs. Kilogram lines on the listings are ceilings, not a pull-out test.
An aircrete fixing is an anchor or screw system for aerated concrete, the soft block used on many UK internal leaves and garage walls, and for plasterboard fixed to that block with dabs of adhesive. A universal wall plug is made for denser masonry. In aerated block the plug can crush the face instead of spreading the load. On a dabbed wall the board is only a skin. The hold has to reach the block behind the cavity, or it is only as strong as the plasterboard. Match the wall before the packet.
A standard wall plug spreads load into a small cone. In soft block that cone crushes the face. Bare block needs a spiral or a metal aircrete anchor. Dabbed board needs a bridge to the masonry.
Bridging plugs crush or break when the hole is dirty, and a hole that stops short wastes a plug. Drill the stated diameter to the stated depth and clear the dust before you seat the fixing.
Hard hammering can loosen aerated blocks or chip an edge, and a hammer-in spiral is not designed to come out. A sleeve binds if you overtighten it with a power tool. Tighten that type by hand.
The first split is the wall you can prove, not the star line. Bare aerated block takes a spiral hammer-in anchor for a mailbox, a rail or a similar modest load, or a metal expansion anchor when the same block will see repeated higher loads. Dot-and-dab takes a fixing that crosses the cavity: a steel core, a sleeve-and-screw bridge, or a two-part plug with a long screw into the masonry. A television kit in that family is for a flush screen.
Use the listing's stated kilograms per fixing as a ceiling. Divide the item weight by the number of points. A four-fixing or six-fixing total is the seller's line for that many fixings, not a higher load on fewer screws. Leave a cantilever television arm off the wall unless that listing allows it. Where the card prints no kilogram, do not invent one from a heavy-duty phrase. Then match the install. Hammer-in spirals need a pre-drill and a hammer, and they are awkward or impossible to remove.
Three typical situations, each with a recommendation from this comparison.
You are hanging televisions, shelves or radiators on plasterboard over lightweight block and you want spare fixings of the same length. The Corefix 100 mm 24-pack is the top pick at about £21.00, with 4.7 from 1,437 ratings. A short hole wastes a plug, and the 10 mm bit is not in the box.
You can see the aerated block, as in a thermobloc garage, and the load is a mailbox, a rail or a similar modest fixing. The fischer GB Green 8 mm 20-pack is about £8.49, with 4.7 from 75 ratings. Hard hammering can loosen the blocks, and the spiral is not designed to come out.
You have one radiator, shelf or flush screen on plasterboard over block. The Corefix 100 mm four-pack is best value at about £6.30, with 4.6 from 1,454 ratings. Dust left in the hole crushes the plug, four pieces leave almost no spare, and a cantilever arm is not recommended.
The top pick is the Corefix 100 mm 24-pack at about £21.00: 4.7 from 1,437 amazon.co.uk ratings, made in the United Kingdom, with bullets that name aerated and lightweight block as well as dot-and-dab. The best value is the Corefix 100 mm four-pack at about £6.30, with 4.6 from 1,454 ratings, the highest value part in the scoring. Four fixings and the dust-crush notes keep its total below the 24-pack. Kilogram lines are listing claims. None of these scores is a pull-out test.
Corefix 100 mm (24)
Highest score: 4.7 from 1,437 ratings, a UK-made 24-pack, and bullets that name aerated and lightweight block as well as dot-and-dab.
Corefix 100 mm (4)
Highest value part: about £6.30 and 4.6 from 1,454 ratings, for one flush job on plasterboard over block.
