Double sided organiser vs removable cups

Updated: 23 October 2026

You are choosing between a flat box that opens on both sides and a deeper case whose bins lift out, and the listings both claim to organise screws as if those were the same object. A double sided organiser vs removable cups is a layout choice. Dividers win when you want many small sizes in about 8 cm of height. Cups win when you take one size to the bench and need the lid to hold the rest still. Brand comes second. The prices and the conflicts sit on the [assortment box comparison](/hub/diy-supplies/assortment-box).

Two layouts, not two brands

A double-sided divider box is a shallow clamshell. In this set that pattern is the Amtech S6463, the ZAVIA ZV379 and the Yoxfayox. A cup organiser is a case of separate bins. You lift one bin out and the lid, when it is shut, stops the others from spilling. In this set the cup case is the Stanley FatMax 1-97-518, with 10 removable cups, metal latches and a clear lid. The Stanley SortMaster 1-94-745 is neither of those layouts. It is a larger single case with removable dividers, about 44.2 × 32.7 × 9.2 cm, at about £9.99. If your shortlist is SortMaster or FatMax, you are choosing a wide divider tray against lift-out cups. How to read the centimetre lines is in the screw organiser buying guide.

When the double-sided box wins

Choose the double-sided box when the shelf is shallow and the stock is many short sizes: wood screws up to about 50 mm, plugs, bits and small nuts. The Amtech bullets say 320 × 260 × 80 mm, so the body is about 8 cm high. The ZAVIA is listed at 32 × 26 × 8 cm. The headline number 34 is both faces, not 34 cells you can see in one glance. The technical table says 81.3 × 20.3 × 66 cm, and reviews say the box that arrived was nothing like that table. Dividers on that model adjust in one direction only. The listing says it is not water resistant. How full to fill a cell is in how to organise screws.

When cups win

Choose removable cups when the way you work is to pick up the 5 × 70 mm and walk. The FatMax listing says the cups are removable and that the lid keeps them from mixing. You can leave nine sizes in the case and take one cup up the ladder. A divider box cannot do that without tipping a whole face. Stanley’s UK page for the 1-97-518 lists metal latches and rates the case IP53. The amazon listing says waterproof. IP53 is spray. The reason to pick cups is the bin, not the rating. One buyer returned a later order that had plastic clasps and no seal. Side latches join other FatMax organisers. They do not join the Amtech, and a DeWalt TSTAK claim in a review is not a specification.

A recommendation with a condition

Buy the Amtech if you trust 320 × 260 × 80 mm and you do not need a rain rating. Buy the FatMax cups if you lift one size out and you will pay about £22.79 for metal latches and an IP53 rating on Stanley’s UK page. Under about 9 cm of height and many short sizes, double-sided. One size walking away from the case, cups. A single wide tray is the SortMaster, which is dividers without being double-sided. That third path is on the best parts organiser page.

Common questions

When is a double-sided box the better buy?
When you want a lot of small sizes in a body about 8 cm high, and you look at one face at a time. The Amtech bullets are 320 × 260 × 80 mm, with about 17 compartments a side in the reviews. It suits a drawer of short screws, plugs and bits. It is the worse buy if you needed the 81 cm figure in the technical table, or if the listing’s not water resistant line rules the van out.
When are removable cups worth it?
When you take one size to the bench or the ladder and leave the other sizes locked in the case. The FatMax 1-97-518 is the cup case in this set, about £22.79, with 10 cups and metal latches. Cups are harder to justify if you never separate one bin and you only needed a shallow drawer organiser. You are paying for the lift-out, not for a higher compartment count.
Will small screws mix in a divider box?
They can. SortMaster reviews often say small parts slip under movable dividers. Amtech reviews go both ways: some say the gap holds panel pins, some say very small parts migrate. A cup case avoids that particular gap because each size sits in its own bin under the lid. Mixing is a reported fault, not a certainty on every divider box, and overfilling makes it worse.
Can I remove FatMax cups and still carry the case?
Yes. That is what the removable cups are for. Take one bin and keep the lid shut on the rest so they do not mix. The listing says the lid holds the compartments. Check you received metal latches, because one later order in the reviews had plastic clasps and no seal. Do not assume the empty space left by one cup is a tray for loose screws.
Is the SortMaster a cup organiser?
No. The SortMaster 1-94-745 is a 12-compartment divider case with a clear lid and removable dividers. Stanley’s UK page describes that layout, not lift-out cups. The cup organiser in this comparison is the FatMax 1-97-518. If you want bins you can remove, the SortMaster will frustrate you even though it is the stronger review file and the lower price.
