Best parts organiser UK

Updated: 23 October 2026

You want one name to type into amazon.co.uk, not a tour of every compartment box on the market. In this set the top pick for most home buyers is the Stanley SortMaster 1-94-745, and the best value double-sided case is the Amtech S6463. The Stanley FatMax 1-97-518 is the one to choose when you need cups you can lift out. Who should skip each of those is the point of this page. The full table, with prices and the conflicts in the listings, is on the [assortment box comparison](/hub/diy-supplies/assortment-box). If you buy through our links, a qualifying purchase can earn us a commission at no extra cost to you. This is not a lab test. Updated 23 October 2026.

The top pick in this set

The Stanley SortMaster 1-94-745 is the top pick here because the evidence is wide and the price is ordinary. Amazon.co.uk shows 4.7 from 9,280 reviews, and the stored shelf price is about £9.99. The bullets and Stanley’s UK page agree on 12 compartments, a see-through lid, a carry handle, and about 44.2 × 32.7 × 9.2 cm. Stanley also prints a 7 kg weight capacity on that UK page. Small items slip under the movable dividers, and a divider can lift out when you pick a screw back out. The amazon technical table says one compartment and a maximum of 1 mg. Those two figures are errors. The listing says waterproof, and Stanley’s UK page for this model does not publish an IP rating.

Best value if you want two sides

The best value pick is the Amtech S6463, at about £13.35 with 4.6 from 883 reviews, when the job is many small sizes in a shallow body. Reviewers describe about 17 slots on each side, so 34 compartments is both faces together. 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. Dividers adjust in one direction only. The listing says the box is not water resistant. Against the ZAVIA ZV379, about £11.99 and 4.9 from only 20 reviews, the Amtech has enough buyer comments to judge. Rain and clipping belong on the parts organiser for a van page.

When the FatMax is the better buy

The Stanley FatMax 1-97-518 costs about £22.79, weighs about 2 kg, and measures about 43.2 × 10.9 × 33 cm. It holds 10 removable cups behind a clear lid, with metal latches. Amazon.co.uk shows 4.8 from 3,700 reviews. You take one cup to the bench and the lid keeps the other nine from mixing. Stanley’s UK page rates this model IP53. That is dust and water spray, not a case you can leave in a bucket. The amazon listing still says waterproof. The complaint that repeats is a glued promotional label across the clear lid. A later order arrived with plastic clasps and no seal. It is worth more than £20 when you will use the cups. It is not worth it when a £9.99 SortMaster already covers a cupboard of wood screws. A review claim that the cups match DeWalt is not a Stanley specification.

What not to crown

A 4.9 from 20 reviews is not a top pick. The ZAVIA ZV379 costs about £11.99. The ZJW at about £7.99 is about 22.5 × 15.5 × 5.5 cm, and reviewers say it is smaller than they expected. The Kistenberg ten-pack at about £53.89 is ten shallow boxes, not one case. If you only buy one, buy the SortMaster unless you need two faces or lift-out cups. If you will trust 320 × 260 × 80 mm, buy the Amtech. If you will walk one size to the bench, or you want the only published IP code in this set, buy the FatMax.

Common questions

What is the best value double-sided box?
The Amtech S6463, at about £13.35 with 4.6 from 883 reviews and 34 compartments across two sides. Trust the bullet size of 320 × 260 × 80 mm, not the 81.3 cm table. It is listed as not water resistant, and the dividers adjust in one direction only. A 4.9 from 20 reviews on a cheaper double-sided box is not a stronger result.
Who should skip the SortMaster?
Skip it if your shelf is under about 40 cm, if you need to carry one size of screw away from the case, or if the van needs a stated IP rating. Also skip it if your fixings are tiny panel pins and you already know dividers let them through, because that complaint is common in the reviews. A loose side latch shows up often enough to check the clips when the parcel arrives.
Is the FatMax worth more than £20?
Yes, if you will use the 10 removable cups and the metal latches, and you accept IP53 as spray protection rather than a waterproof dunk. At about £22.79 and 4.8 from 3,700 reviews it is the cup case in this set. No, if a divider tray at about £10 already matches the way you work. Label glue on the lid is the complaint to expect, not a cracked shell.
Is a 4.9 from 20 ratings enough to call a box the best?
No. The ZAVIA’s 4.9 from 20 is a short file with no repeated defect in the seven texts we stored, which is pleasant and still too thin. A top pick in this comparison needs a review count large enough that a latch fault would have shown up. The SortMaster’s 9,280 reviews and the FatMax’s 3,700 reviews clear that bar. Twenty does not.
Can I treat review rank as a lab test?
No. Nobody in this comparison measured crush strength, latch cycles or a spray booth. Stars and review counts are amazon.co.uk figures, and a high sales rank only says the listing sells. IP53 on the FatMax comes from Stanley’s UK page for that model number, not from a test we ran.
