21mm Self-Adhesive Screw Hole Cover Caps — Clean Finish, Zero Tools

Exposed screw heads and unused pre-drilled holes are one of the most common frustrations after assembling flat-pack furniture. Whether you're finishing a kitchen cabinet, wardrobe, bookshelf, or desk, these 21mm peel-and-stick screw hole cover caps let you hide every imperfection in seconds — no glue, no drill, no mess.

Each cap is made from durable, waterproof PVC with a strong self-adhesive backing. At 21mm in diameter, they cover the most common furniture hole sizes found in IKEA-style and flat-pack pieces. Available in 27 colors and finishes — including wood grains (Apple Wood, Grey Oak, Black Walnut, Classic Teak, American Oak), solid colors (Warm White, Pure Black, Light Gray, Ivory), cloth textures, and matte relief finishes.

Use them to cover cabinet handle screw holes, hide nail heads on shelving units, seal unused pre-drilled holes on wardrobes, or finish off any wooden surface where you want a clean, professional look. Sold in sheets of 54 pcs — choose 1, 2, 3, 5, or 10 sheets to match your project size.

Compatible with wood, MDF, particle board, laminate, and smooth painted surfaces. Ideal for IKEA, flat-pack, and custom-built furniture.

✅ Key Features of These Self-Adhesive Screw Hole Cover Caps

  • 🏷️ Peel-and-Stick Installation: Self-adhesive backing means no glue, no tools, no mess. Peel from the sheet, position over the hole, press firmly for 10 seconds — done.
  • 📐 21mm Diameter Fits Most Furniture Holes: Covers pre-drilled holes, exposed screw heads, and nail heads up to 21mm wide — the standard size for most flat-pack and cabinet hardware.
  • 🎨 27 Colors & Textures: Wood grains (Apple Wood, Oak, Walnut, Teak), solid colors (White, Black, Gray, Ivory), cloth patterns, and matte relief finishes — match virtually any furniture style.
  • 💧 Waterproof PVC Material: Moisture-resistant and fade-proof. Safe for kitchens, bathrooms, and high-humidity environments. Won't crack, warp, or discolor over time.
  • 🔩 Protects Screws from Rust: Sealing the screw head prevents moisture contact, extending the life of your hardware and keeping your furniture looking newer for longer.
  • 📦 Flexible Pack Sizes: Available in 1 sheet (54 pcs), 2 sheets (108 pcs), 3 sheets (162 pcs), 5 sheets (270 pcs), or 10 sheets (540 pcs) — scale to your project without waste.

❓ Frequently Asked Questions

Will these caps stick permanently or fall off over time?

The adhesive is strong enough for years of normal indoor use. For best results, clean the surface with rubbing alcohol before applying — this removes dust and oils that weaken adhesion. Once pressed firmly for 10 seconds, they resist daily wiping and moderate humidity. They are not designed for outdoor use in direct rain or submersion.

Can I remove them later without damaging the furniture?

Yes — carefully peel off the cap using a plastic pry tool or your fingernail. If adhesive residue remains, remove it with rubbing alcohol or a mild adhesive remover (test on an inconspicuous area first). The caps are not designed for reuse after removal.

How do I match the cap color to my furniture?

Browse the 27 color options in the variant selector. For wood furniture, Apple Wood (40#), American Oak (430#), Black Walnut (279#), Classic Teak (101#), or Grey Oak (68#) are popular choices. For white cabinets, Smooth Warm White (04#) or Bright White (27#) work well. If unsure, order a small quantity of a few shades to test before committing to a larger pack.

Can I use these on pre-drilled holes that don't have screws?

Absolutely. Many flat-pack furniture pieces have unused pre-drilled holes from alternative assembly configurations. Simply stick a cap directly over the empty hole — it covers it completely and looks like part of the design. No screw is needed underneath.

Are these waterproof? Can I use them in a kitchen or bathroom?

Yes — the PVC material is waterproof and the adhesive is moisture-resistant for typical kitchen and bathroom humidity (near sinks, steam, etc.). Avoid direct water spray or submersion. Wipe gently with a damp cloth — do not scrub aggressively.

What's the difference between the color board options and the regular caps?

The Colour Board A (400 colors) and Colour Board B (140 colors) options are physical color sample boards for comparison purposes only — they are not functional caps. Order these if you want to compare shades against your furniture before purchasing caps in bulk. Regular cap variants (1–10 sheets) are the actual peel-and-stick covers.

How many caps do I need for a typical wardrobe or kitchen cabinet project?

A typical flat-pack wardrobe typically has 20–40 visible screw holes. A kitchen with 10 cabinet doors may have 40–80 handle holes to cover. The 1-sheet pack (54 pcs) suits small projects; the 5-sheet (270 pcs) or 10-sheet (540 pcs) packs are better value for larger renovations.
