The best assortment boxes, compared.
Top pick: ZAVIA ZV379 34-compartment box Best value: Amtech S6463 double-sided box – About £13.35 with 4.6 from 883 reviews for a 34-cell double-sided case. Listed as not water resistant. Updated 22.10.2026.
An assortment box is a lidded plastic case that keeps screws, nuts, bolts, nails and other small fixings in separate cells. You buy one when a jam-jar drawer or a van shelf has become a mix of sizes. You judge it by whether the lid and the latches stop parts hopping the walls, not by the compartment count alone. The two layouts that matter are a divider grid, often double-sided, and a case of removable cups. On amazon.co.uk, honest outer size sits roughly between a 22 cm pocket box and a 44 cm organiser. Stanley’s UK page rates the deep organiser 1-97-518 at IP53. A listing that only says waterproof is not the same fact. How to read a size line that disagrees with the photos is in the [assortment box buying guide](/hub/diy-supplies/assortment-box/sub/assortment-box-buying-guide). Bullets and the manufacturer say 12 compartments and about 44.2 × 32.7 × 9.2 cm.

Question 1 of 2
Which layout do you need?
The ZAVIA ZV379 is a transparent double-sided box at about £11.99, listed as 32 × 26 × 8 cm with 34 compartments and 24 partition cards. Amazon.co.uk shows 4.9 from 20 reviews. The seven texts in the file praise the compartment count, a strong feel, lids and clips, and the chance to move dividers so a cell will take screwdrivers or pliers. More than one reviewer calls it good value. None of those seven texts repeats a defect, which is encouraging and also a small sample. The listing says water resistant and lockable, without an IP code, and it does not state a dedicated carry handle. Twenty ratings at 4.9 are not the same evidence as several thousand reviews on the Stanley cases, so this stays a promising double-sided option rather than the top pick.
Pros
Cons
Best for: You want a double-sided 34-cell box near £12 and will check newer reviews before you rely on the 4.9.
Less suitable: You want the case with the longest UK review record, or a published IP rating.
Specifications
Common questions
Can the ZAVIA compartments be resized?
Yes. The listing includes 24 partition cards and says the dividers are removable. A review mentions making cells large enough for screwdrivers and pliers.
Is it water resistant?
The listing says water resistant. It does not give an IP code.
The Stanley FatMax 1-97-518 is a deep organiser with 10 removable cups, metal latches and a clear lid, listed at about £22.79 and 2 kg, with outer size 43.2 × 10.9 × 33 cm. On amazon.co.uk it is 4.8 from 3,700 reviews. Buyers praise thick plastic, cups that stay put when the lid is shut, and metal latches they prefer to plastic clasps, and they use the cups for screws, plumbing fittings, cable clips and electronics parts. One reviewer used it in rain and reported no water inside, while Stanley’s UK page rates this model IP53, which is spray resistance rather than a soak, even though the amazon listing says waterproof. The repeated nuisance is a glued promotional label across the clear lid. One deep unit had looser metal latches than the buyer’s shallow FatMax cases, and a later order was returned because it arrived with plastic clasps and no seal. Side latches clip other FatMax organisers, and a review claim that the cups match another brand is not a specification. Choose it when you want to lift one cup to the bench.
Pros
Cons
Best for: You want to carry one cup of a single size to the bench and clip another FatMax case on.
Less suitable: You only need a cheap divider tray for a cupboard, or you need immersion protection.
Specifications
Common questions
Does the FatMax 1-97-518 have removable compartments?
Yes. The listing says 10 removable and stackable compartments, with a lid that keeps them from mixing.
Is this FatMax waterproof?
The amazon.co.uk listing says waterproof and describes a seal against water, rust and dust. Stanley’s UK page rates this model IP53, which is spray resistance, not immersion.
Will it clip to another box?
The listing says side latches let you clip multiple FatMax organisers together.
The famuka GJX-01--UK is three red stackable boxes at about £19.99, listed as 31.3 × 22 × 19.5 cm overall and 1.91 kg, with 30 compartments in total and six removable dividers in each layer. Amazon.co.uk shows 4.8 from 10 reviews. The four texts call the set well built, note that the layers lock together and can be used separately, and one buyer uses a layer for feeder fishing rather than screws. The complaint that does appear is practical: the stacked catches were very stiff to pull apart. The listing says waterproof and does not give an IP code. Ten reviews are a short record next to the Stanley and Amtech files, so the 4.8 is a start rather than a settled score. It suits someone who wants three shallow trays that can travel as one stack, and it is a weak pick if you wanted a single case with thousands of reviews.
Pros
Cons
Best for: You want three shallow trays that stack into one 1.91 kg unit and can also be used apart.
Less suitable: You want one proven case, or latches you can separate without a fight.
Specifications
Common questions
Can the famuka boxes be used separately?
Yes. The listing says each of the three layers can be used on its own or stacked.
Do they stack securely?
The listing says two side latches lock the lid and allow stacking. One review says the stacked catches were very stiff to pull apart.
The Stanley SortMaster 1-94-745 is a large divider organiser at about £9.99, with a clear lid, a textured carry handle and side latches that clip to other SortMaster cases. On amazon.co.uk it is 4.7 from 9,280 reviews, and the listing bullets plus Stanley’s UK page both describe 12 compartments at about 44.2 × 32.7 × 9.2 cm. Reviewers often say it is larger than they expected and use it for screws, nails, wall plugs and cable clips, with clasps that stay shut when the case is full. The recurring fault is mechanical: small items slip under the movable dividers, and a divider can lift out when you fish a screw back. A few buyers also report a loose yellow side latch. The same listing’s technical table includes figures that are not usable, and the waterproof word has no IP code on the amazon page or on Stanley’s UK sheet. In this set it is the top pick for a home shelf when you want one trusted case at about £10, and a poor match if you need lift-out cups or a published spray rating.
Pros
Cons
Best for: You want one large divider case for a shed or cupboard and will keep cells below the divider walls.
Less suitable: You need to lift a single bin to the bench, or you need a published IP rating for a van.
Specifications
Common questions
How many compartments does the SortMaster 1-94-745 have?
The listing bullets say 12 compartments with removable dividers. Stanley’s UK page agrees. A conflicting count on the same listing’s technical table is not the figure to use.
Can it clip to another organiser?
The listing says side latches let you clip similar SortMaster organisers together. It does not say they fit other brands.
Is it waterproof?
The amazon.co.uk listing says waterproof. The saved listing does not include an IP code, and Stanley’s UK page for this model does not publish one either.
The Amtech S6463 is a double-sided 34-compartment screw box at about £13.35, with 4.6 from 883 amazon.co.uk reviews. Reviewers describe about 17 slots on each side, independent lids, clear faces and locks that hold screws, bits and plugs, and several say it replaced a pile of separate tubs. The size story on the page is the problem you have to settle before you buy: the bullets say 320 × 260 × 80 mm, the technical table says 81.3 × 20.3 × 66 cm, and reviews say the box that arrived was much smaller than that table. Trust the millimetre line. Dividers adjust in one direction only, and the cells still suit smaller screws more than long fixings. A gap that some buyers praise for panel pins lets very small parts migrate for others, and one unit arrived broken after loose packaging. The listing says it is not water resistant. In this set it is the best value when you want two faces of small fixings in a case about 32 cm long, and the wrong box if you needed the 81 cm table to be true.
Pros
Cons
Best for: You want many small screw sizes in a shallow double-sided case and will ignore the 81 cm table.
Less suitable: You need an 80 cm box, long fixings, or a case rated for rain.
Specifications
Common questions
How big is the Amtech S6463?
The bullets say 320 × 260 × 80 mm. The technical table says 81.3 × 20.3 × 66 cm. Reviews say the box that arrived was much smaller than that table.
Is it water resistant?
The listing says not water resistant.
Can you change the compartment sizes?
Yes. The listing says the partitions are adjustable, and reviews describe removable dividers. One review says they adjust in one direction only.
The Kistenberg listing is a pack of 10 clear NORS14 boxes, model KNO35255S, at about £53.89 and 4.4 kg, each about 34.4 × 24.9 × 5 cm with a clip-on lid, dividers and a handle. Amazon.co.uk shows 4.6 from 752 reviews, but only three review texts were saved with the listing, so that star line is not the same as a close reading of 752 comments. Those three texts are mostly about fulfilment and moulding: one order arrived as a single box and the seller later put the quantity right, another describes cracked lids and divider lumps that had to be sanded before the lid would shut, and a third says the boxes do not stack even though the listing marks them stackable. The page says not water resistant. The pack is a workshop set rather than a single organiser, and it is the wrong order if you only need one case.
Pros
Cons
Best for: You want ten shallow clear boxes for a workshop and will check the parcel contains ten.
Less suitable: You need one portable case, a rain seal, or boxes you can stack without a dispute.
Specifications
Common questions
How many boxes are in the Kistenberg set?
The title and bullets say 10 NORS14 boxes. One review says only one arrived at first, and the seller later put that right.
Are they waterproof?
The listing says not water resistant.
Do they stack?
The listing marks them as stackable. One review says they do not stack and sent them back.
The ZJW polypropylene box measures about 22.5 × 15.5 × 5.5 cm, with 10 compartments and a lockable lid, and amazon.co.uk lists it at £7.99. Across 324 reviews it sits at 4.3, and the buyers who like it use it for small screws, washers and drill bits that live inside a larger toolbox. Several say the clip feels solid and that some compartments come out. The same threads keep returning to size: it is smaller than they expected, and too small to stand in as a full tool box. A few call it overpriced for that footprint and compare it with a cheaper multi-pack of similar boxes. One buyer received a unit with the lid-retaining bar and the clip already broken. The listing calls it water resistant and gives no IP code, so that line is a seller claim rather than a tested seal, and at 280 g it is a drawer box rather than a van case.
Pros
Cons
Best for: You want a light 10-cell box for small screws and bits inside a drawer or a larger toolbox.
Less suitable: You need a main organiser for long fixings, or a case you will carry in the rain.
Specifications
Common questions
Will this ZJW box hold screws?
The listing says it is for screws, drill bits and small parts, with 10 compartments and removable dividers.
How big is it?
The technical table says 22.5 × 15.5 × 5.5 cm. A bullet says 22 × 15 × 5.5 cm. Reviews often call it smaller than expected.
The BLLREMIPSUR hardware box is about 29 × 22.8 × 5.8 cm, with 16 compartments, four removable partitions and a top handle, listed at £10.99. The amazon.co.uk line is 4.0 from 12 reviews, and only four review texts were saved with the listing, so the sample is thin. Those buyers call it useful for a drawer of mixed screws and say the dividers help, with one describing it as good for the price. No complaint repeats across those four texts. The water line does not agree with itself: the technical table says water resistant and the bullets say waterproof, and neither gives an IP code. At 520 g it is a shallow polypropylene case, not a deep cup organiser. Twelve reviews are not enough to treat the 4.0 as a settled picture of the latches or the lid.
Pros
Cons
Best for: You want a shallow 16-cell drawer box and will treat the thin review file as unfinished evidence.
Less suitable: You are choosing on star rating alone, or you need a stated spray rating.
Specifications
Common questions
Does this box have a handle?
Yes. The listing says there is a top handle and a locking latch.
Is it waterproof?
The bullets say waterproof and the technical table says water resistant. Neither line includes an IP code.
The Yoxfayox listing is a red double-sided polypropylene box at about £15.99, given as 32 × 27 × 8 cm and 764 g, with clear lids, a carry handle and removable dividers on both sides. The saved amazon.co.uk file has no customer-review line and no review text, so there is no star rating to quote. The compartment count is not stated, the included-components field does not name the contents, and the water line is only water resistant, with snap-lock latches described as limiting dust and moisture and no IP code. Stackable is a listing claim without a buyer report behind it. On paper it sits in the same footprint as the Amtech and the ZAVIA, at a higher price and with none of their review record. In this capture it cannot be ranked against boxes that buyers have actually described.
Pros
Cons
Best for: You have checked a live review count on amazon.co.uk and still want this footprint.
Less suitable: You are comparing boxes on reviews, because this capture has none.
Specifications
Common questions
Are the dividers adjustable on both sides?
Yes. The listing says removable slide-out dividers on both sides of this double-sided box.
Does the listing show a star rating?
No customer-review line was in the saved listing, so the rating is not available.
Shelf prices, star lines and review counts are the figures stored from the amazon.co.uk listings for these nine boxes. Review themes come from the notes saved with those listings. Stanley’s UK pages are used only where a model number is confirmed: SortMaster 1-94-745 for the compartment count and size, and FatMax 1-97-518 for IP53. This is not a laboratory test. A centimetre or a water word is the seller’s claim unless a review or the manufacturer page agrees. Where the bullets and the catalogue disagree, the conflict is a deduction.
Amazon evidence
35%Star rating on amazon.co.uk, then the review count. A 4.7 from 9,280 or a 4.8 from 3,700 carries this block. A 4.9 from 20 does not. The Yoxfayox listing has no star line, so it takes almost none of it.
Spec honesty
25%A stated layout whose size lines agree: dividers or cups, a usable compartment count, and a water word you can read strictly. A waterproof dropdown with no IP code scores below a published IP53.
Review outcome
25%Repeated comments about latches, dividers, cups and the size that arrived. Parts slipping under dividers, a broken clip on arrival, and a ten-pack that arrived as one box are deductions. A file with four texts cannot fill this block the way a long review file can.
Value
15%Stored GBP price for the job the listing actually is. About £9.99 for a large 12-cell case with thousands of reviews scores as value for a home shelf. The best-value badge is reserved for the double-sided case. A £53.89 ten-pack is a different purchase.
Buy the centimetres and the layout before the compartment count. An assortment box on amazon.co.uk in this set is a shallow divider, a double-sided divider, a case of removable cups, or a stack of boxes. Honest outer size sits roughly between 22 cm and 44 cm. A single case is about £8 to £23. A ten-pack is a different order. A listing that only says waterproof is not the same fact as IP53 on the FatMax 1-97-518.
An assortment box, for a UK DIY shopper, is a lidded plastic case that keeps screws, nuts, bolts, nails and other small fixings in separate cells. People buy one when a jam-jar drawer or a van shelf has become a mix of sizes. They judge quality by whether the lid and latches stop parts hopping the walls, not by the compartment count alone. The two layouts that matter are a divider grid, often double-sided, and a case of removable cups.
The Amtech S6463 bullets say 320 × 260 × 80 mm. The same listing’s table says 81.3 × 20.3 × 66 cm. Reviews say the box that arrived was much smaller than that table. Use the millimetre line.
On the Amtech, reviewers describe about 17 slots on each side. A double-sided count is not one grid of 34 on the face you open first. Fill each cell below the divider wall.
SortMaster side latches are described for similar SortMaster organisers. FatMax side latches are described for other FatMax organisers. A review claim that the cups match another brand is not a specification.
Outer size is the first check, and it has to come from the bullets and from a review that measured, not from a technical table that disagrees with the photos. In this set the honest range runs from the ZJW at about 22.5 × 15.5 × 5.5 cm to the SortMaster at about 44.2 × 32.7 × 9.2 cm. The Amtech conflict is the one to remember: bullets 320 × 260 × 80 mm, table 81.3 × 20.3 × 66 cm, and reviews reject the table.
Layout is the second check. Removable dividers suit many small sizes in a shallow body. The Amtech, the ZAVIA and the Yoxfayox are the double-sided rows around 32 × 27 × 8 cm. Removable cups suit lifting one bin to the bench, which is the FatMax 1-97-518 with 10 cups and a lid that holds them. Latches are the wear point. Metal latches are the FatMax pattern.
Three typical situations, each with a recommendation from this comparison.
You need a box that fits a shed shelf or a hallway cupboard, and you will accept a sub-£14 divider case if the centimetres are honest. The Stanley SortMaster 1-94-745 is the top pick at about £9.99, with 4.7 from 9,280 reviews and 12 compartments that match Stanley’s UK page. Keep cells below the divider walls. Small parts can slip underneath.
You carry fixings in the car and you want either a long review record or cups you can lift out. The SortMaster has the review volume. If you want one cup at the bench, step up to the Stanley FatMax 1-97-518 at about £22.79, with 10 removable cups, metal latches and 4.8 from 3,700 reviews. Stanley’s UK page rates that model IP53.
You are choosing a case that travels, so seals, metal latches and same-family clips matter more than a high compartment count. The FatMax 1-97-518 is the model with metal latches and IP53 on Stanley’s UK page. IP53 is spray resistance, not immersion. Side latches clip other FatMax organisers. They are not specified to fit another brand.
The top pick is the Stanley SortMaster 1-94-745 at about £9.99. It scores 94, the highest here: 4.7 from 9,280 reviews, and 12 compartments at about 44.2 × 32.7 × 9.2 cm that match Stanley’s UK page. Small parts can slip under the dividers, and the waterproof line has no IP code. Best value is the Amtech S6463 at about £13.35, a double-sided 34-compartment case with 4.6 from 883 reviews, if you trust the bullet size of 320 × 260 × 80 mm and you do not need a water rating. The FatMax 1-97-518 scores 90 and does not take a badge: 10 removable cups, metal latches and IP53 on Stanley’s UK page, at about £22.79.
