FastCap’s white screw covers solve the finishing problem that wood plugs and putty can’t match — instant coverage with zero sanding. The 9/16-inch adhesive caps stick permanently to cabinet boxes, trim work, and furniture assemblies where visible screws ruin the look. At 52 caps per sheet, they’re sized for professional jobs, not weekend touch-ups.
The Ultra-Bond PSA adhesive makes these different from generic stick-on caps. High-performance acrylic ‘Ultra-Bond’ Pressure-Sensitive Adhesive (PSA) creates a bond that gains strength as it cures (permanent bond). You get about 30 seconds to reposition if you miss your mark. After 24 hours, they’re permanent.
Skip these if you’re covering outdoor fasteners or need structural support. The UV-stable PVC holds up indoors, but high UV exposure may lead to minor fading outdoors. They’re cosmetic covers, not load-bearing plugs.
Professional Speed vs Traditional Methods
Professional woodworkers often prefer them for ‘invisible’ finishes on white cabinetry. The math is simple — no pilot holes, no glue, no sanding. Wood plugs can be stained to match exactly, but they Requires drilling pilot holes, sanding, and often glue; much more time-consuming to install.
The installation breaks down to five steps that take seconds per cap:
- Clean the target surface thoroughly to remove dust, oil, grease, or residue. Ensure the surface is completely dry and flat.
- Peel the individual cap off the backing sheet. Align the cap over the screw hole or fastener head.
- Press firmly for several seconds to activate the pressure-sensitive adhesive.
The adhesive reaches full bond strength within 24 hours. That’s the difference — repositionable early, permanent later.
Where These Caps Earn Their Keep
The Semi-hard PVC (Barium/Cadmium-free stabilized) material works on eight different surfaces:
| Surface Type | Application Notes |
|---|---|
| Finished wood | Direct application |
| Unfinished wood | Clean thoroughly first |
| MDF | Temperature-sensitive in Montana’s dry climate |
| Particleboard | Standard cabinet boxes |
| Laminate | Factory cabinets |
| PVC | Trim and components |
| Metal | Clean surface critical |
| Plastic | Various applications |
Cabinet installers use these for Hiding plumbing cut-outs in sink cabinets and Concealing fastener holes in RTA (ready-to-assemble) kits. The white color matches standard melamine and painted finishes without touch-up.

FAQ
Q: How permanent is the adhesive bond?
The Ultra-Bond PSA adhesive starts repositionable but gains strength as it cures (permanent bond). You get a short window for adjustments, then The adhesive reaches full bond strength within 24 hours. After that, removal means damage.
Q: Will these work on oily wood surfaces?
May struggle to adhere to very oily or heavily waxed surfaces. Clean any surface with denatured alcohol first. The adhesive needs direct contact with the substrate, not the oil film.
Q: Can I use these outdoors on deck screws?
No. While the PVC is UV-stable material (though high UV exposure may lead to minor fading outdoors), these are designed for interior applications. Montana’s freeze-thaw cycles and UV exposure will compromise outdoor performance.
Q: Do these meet food safety requirements for kitchen cabinets?
Not rated for food contact (not dishwasher/microwave safe). They’re fine for cabinet exteriors but not for direct food contact surfaces. The material contains California Proposition 65 warning (applies to some PVC products).
Q: What size screw heads do these cover?
The 9/16 inch (approx. 14 mm) diameter covers standard cabinet screws. Some users find the 9/16” size slightly too small for very large screw heads, so check your fastener sizes first.
