If you manufacture fitted furniture at volume, a screw cover cap is not a finishing touch. It is a component with a colour specification, a batch tolerance and a lead time — and it fails in public.
Most content about screw cover caps is written for someone standing in a room with a screwdriver. This one is written for the person raising the purchase order.
Colour-matched caps behave differently when you buy 200 of them and when you buy 200,000 of them. At volume, the questions stop being "does this look right" and start being "will the batch I order in nine months still match the batch on the shelf today", "how does this land on my packing line", and "what happens when my board supplier introduces a new décor". Those are procurement questions, and they rarely get answered on a product page.
This is a guide to specifying and sourcing colour-matched screw cover caps as a manufacturing input. KwikCaps™ is our own brand — we match, produce and supply it — so the examples are ours, but the specification logic applies whoever you buy from.
What you are actually buying is a colour system
A cap is a disc of printed foil with an adhesive backing. The disc is trivial. The value sits entirely in the colour reference behind it.
Board manufacturers do not share a colour vocabulary. Egger's "Cashmere Grey" and another supplier's "Cashmere Grey" are not the same grey. Colour names drift between ranges, between years and between markets. Décor codes do not. This is why every match in the KwikCaps range is held against a code — Egger H3368, U702 ST9, Finsa 9AR, and so on — with the colour name carried alongside it as a convenience rather than as the identifier.
For a manufacturer, the practical consequence is straightforward: specify caps by the décor code on your board order, not by the colour name on your cutting list. If your board is bought by code, your caps should be too. Anything else introduces a translation step, and translation steps are where mismatches come from.
We hold matches across over 250 references. The Egger matched range and the Finsa matched range are maintained as separate collections precisely so a buyer can work from the board manufacturer they actually specify, and a growing number of Kronospan matches are being added alongside them.
The six things to put in a bulk enquiry
A quote request that contains all six of the following can usually be answered in one exchange. One that contains two of them takes a fortnight.
- Décor codes. Every board reference you run, by code. Include the texture suffix where you have it (ST9, ST12, ST19) — texture affects how a matched cap reads under light, not just colour.
- Cap diameter. Driven by your screw head and your drilling, not by preference. See the sizing table below.
- Volume by colour, not in total. "50,000 caps a year" is not quotable. "30,000 in two whites, 12,000 across four oaks, 8,000 spread across everything else" is. The distribution matters more than the total, because it determines run sizes.
- Pack format. How you want them to arrive — sheeted, bagged, boxed by colour, or split into job kits. This is the question most buyers forget and most production managers care about most.
- Labelling requirements. Whether caps need your own part numbers, barcodes or branding for your production or packing line.
- Delivery schedule. One drop, quarterly calls, or scheduled against a rolling forecast. Scheduled supply against a forecast is usually both cheaper and more consistent than repeat ad-hoc orders.
If you can supply those six lines, you can get a real answer. Send them through our trade supply form and we will come back with a costed position rather than a brochure.
Sizing: 13mm, 14mm and 20mm
Three standard diameters cover almost all cabinet and panel work, all produced at 0.3mm thick so the cap sits flush rather than proud of the surface.
| Size | Typical use | Notes for specification |
|---|---|---|
| 13mm | Smaller screw heads, tighter panel work | Limited colour availability. Check your décor is held in 13mm before specifying it as standard. |
| 14mm | Standard cabinet, carcass and panel fixing | The default. Widest colour range by a large margin — if you are standardising on one size across a plant, this is it. |
| 20mm | Larger heads, cam fittings, enlarged or reworked holes | Worth carrying as a secondary size for rework and remedial work even if 14mm is your production standard. |
Custom diameters are available on request where a fixing or a machining operation demands it.
One practical note that costs manufacturers money when it is missed: specify the cap size against the hole you actually produce, not the screw you buy. A countersunk head that sits into a machined recess presents a different diameter to the same screw driven flush into a flat face. If your CNC programme creates a recess, measure the recess.
Batch consistency is the real risk, not the initial match
Getting the first match right is the easy part. Any competent supplier can send a sample that looks correct next to a board sample.
The risk that actually shows up in a finished kitchen is different. A manufacturer does not use one batch of caps on one job. Caps from a batch delivered in March end up on a carcass that gets installed alongside a panel finished with caps from a batch delivered in September. Both batches looked right in isolation. In the same installed room, under the same downlights, a small drift between them is visible — and it is visible to the end client, in a kitchen your name is on.
So the question to put to any supplier is not "does this match my board". It is "what is your process for holding this match across repeat runs, and what happens if a run drifts". The answer tells you whether you are buying from a manufacturer or from a box-shifter.
It is also the reason to buy direct. KwikCaps™ is a trademark of Bedrooms Plus — we hold the colour references ourselves. When a match needs checking, correcting or re-standardising, that happens in-house rather than being relayed through a distributor to a factory that has never seen your board.
When your board supplier introduces a new décor
Egger and Finsa refresh their ranges. A décor you have run for six years gets discontinued, or your design team specifies something introduced last season. Either way there is a window where you are producing furniture in a finish that has no matched cap.
For most buyers this surfaces late — usually when a production manager asks what to do about a run that is already cut. Handled properly it is a scheduling question, not a crisis:
- Flag new décors at specification stage, not at production stage. The moment a new board reference enters your range, it should generate a cap enquiry.
- Send a physical board sample, not a code. For a décor not yet in the range, a code tells a supplier what to buy; a sample tells them what to match. Send both.
- Ask about run-out stock on discontinued décors. If you have installed furniture in the field, you will need matching caps for remedial work long after the board itself has gone.
Bespoke matching to a décor outside the standard range is something we do routinely rather than as an exception. If you are specifying a board we do not currently hold, that is a conversation, not a dead end.
How caps land on your line
Two manufacturers buying identical caps in identical volumes can want them delivered in completely different formats, because the caps are doing different jobs.
If caps are applied in your factory, you want them bulk, by colour, in a format your operators can work from at a bench without decanting. Our standard 14mm bulk box holds 625 caps, which suits a single-station run in one colour; beyond that, pack size should be driven by your station throughput rather than by our retail packaging.
If caps ship with the product — flat-pack kitchens, RTA furniture, dealer-assembled units — the cap is part of the hardware pack. It needs to arrive in a format that drops into your kit-packing operation without a repackaging step, and it may need to carry your part number rather than ours. That is a different specification entirely, and it should be agreed at quote stage rather than discovered at first delivery.
If caps go to your installation teams, the useful unit is a job-sized kit in the two or three colours that team is actually running that week, not a full colour library. We have written separately about what a fitter realistically carries in a van, and the logic scales directly to a supplied install team.
Custom packaging and private labelling are both available. Tell us which of the three situations above describes your operation and the pack format follows from it.
The commercial case, in the only terms that matter
A cap costs pennies. A remedial visit does not.
The arithmetic a buyer should run is not cost-per-cap against a cheaper cap. It is cost-per-cap against the cost of the failure mode the cap prevents. Visible screw heads on a gable, a stile or an end panel are one of the most common triggers for a snag on an otherwise complete installation — and a snag on a finished kitchen costs a return visit, an installer day and a delayed sign-off.
The same logic runs the other way on quality. A cap that is visibly the wrong shade, or that lifts at the edge after six months in a warm room, does not save you the cost of the cheaper cap. It creates the exact defect you bought caps to avoid, at scale, across every unit that batch went into. Component cost is the wrong thing to optimise when the component's entire purpose is defect prevention.
We have made the related argument at installer level in hidden fixings without the hidden costs — that a colour-matched cap achieves most of what an expensive concealed connector system achieves, on the surfaces a client actually sees. At manufacturing volume that gap compounds considerably.
Specify the repair as well as the fixing
Screw covers solve one defect. Transit damage, handling marks and site knocks are a different one, and they arrive at the same customer.
Our wax repair crayons are mapped to the same décor codes as the caps. One code reference covers both the screw and the scratch, which means your production, your QC and your service teams work from a single colour system rather than cross-referencing two. For a manufacturer running warranty or remedial work, that is a meaningful administrative saving on top of the obvious one.
The same applies to fixings. If you are already specifying Reisser cutter screws or similar, consolidating caps, crayons and screws with one supplier removes a set of purchase orders rather than adding one.
Starting a supply conversation
Three steps, in this order.
1. Verify the match physically. Order the A4 fold-out sample sheet and hold it against your actual boards, under your actual lighting. No screen assessment of a colour match is worth anything. This costs £5 and settles the question in a day.
2. Run a trial quantity. A single production batch through your real process — your operators, your line speed, your packing. Adhesion, handling and application behaviour all show up here and nowhere else.
3. Move to scheduled supply. Once the specification is settled, scheduled delivery against a forecast beats repeat ad-hoc ordering on price, consistency and stockholding.

Frequently asked questions
Can screw cover caps be matched to a specific Egger or Finsa board code?
Yes. KwikCaps are matched at décor-code level rather than by colour name. You supply the Egger décor reference (for example H3368 or U702 ST9) or the Finsa reference, and the match is made against that code. This matters because colour names are not consistent between board manufacturers, whereas décor codes are.
What information does a supplier need to quote for bulk screw cover caps?
Six things: the board décor codes you use, the cap diameter required, your annual or quarterly volume by colour, the pack format you want the caps delivered in, whether you need them labelled for your own production or packing line, and your delivery schedule. Supplying all six at enquiry stage removes most of the back and forth.
What sizes do self-adhesive screw cover caps come in?
KwikCaps are produced in 13mm, 14mm and 20mm, at 0.3mm thick. 14mm is the standard size for most cabinet and panel work and covers the widest range of colours. 20mm is used where a larger screw head, a cam fitting or a slightly enlarged hole needs covering. Custom sizes are available on request.
How many screw cover caps come in a bulk box?
A 14mm bulk box contains 625 caps. For manufacturers running scheduled supply, pack format and quantity per unit are agreed as part of the supply arrangement rather than fixed to the standard retail pack.
Why does colour consistency between batches matter for furniture manufacturers?
A manufacturer does not use one batch of caps on one job. Caps from a batch delivered in March may end up on a carcass that sits next to a panel finished with caps from a batch delivered in September, in the same installed kitchen. If the two batches differ, the variation is visible in the finished room even though each batch looked correct on its own. Consistency across repeat orders is therefore a specification requirement, not a nice-to-have.
Can screw cover caps be supplied in custom colours or bespoke packaging?
Yes. Bespoke colour matching to a décor outside the standard range is available on request, as is custom packaging and labelling for manufacturers who want caps supplied ready for their own kit-packing line. Both are handled as part of a trade supply arrangement rather than a standard online order.
Who manufactures KwikCaps screw cover caps?
KwikCaps is a trademark of Bedrooms Plus Ltd, a UK family business established in 1980 and based in Hamilton, Scotland. Buying direct means colour matching, new décor introductions and bespoke requirements are handled by the brand owner rather than passed along a distribution chain.
