End Caps & Screw Protectors

End Caps & Screw Protectors keep fasteners safe, tidy, and professional-looking. These simple add-ons cover sharp threads and bolt heads, helping prevent injuries, snags, and wear. They seal out dust and moisture, reduce corrosion on exposed threads, and quiet vibration or rattles in equipment and furniture. For clean finishes on projects, end caps also hide cut tube ends and hardware for a polished, uniform look.

You’ll find a broad range of materials to match your application. Flexible vinyl and PVC push-on caps slide over screws and studs for quick protection. Nylon and polyethylene nut covers provide a durable, low-profile finish on hex nuts and bolts. Rubber and silicone caps add grip and cushion, with options that handle higher temperatures or resist oils and chemicals. For outdoor and marine use, look for UV-stable and salt-spray-tested caps. Many styles come in multiple colors for easy identification or branding.

Common types include bolt caps, nut covers, thread protectors, tube end caps (round, square, and rectangular), ribbed push-in caps for metal tubing, chair leg caps to protect floors, and flange caps for ports and fittings. Sizes are available for both metric and imperial hardware.

How to choose the right cap:
- Measure accurately: match ID/OD to the screw, nut, or tube. For nut covers, use the across-flats dimension.
- Consider environment: outdoor exposure, UV, salt, temperature, and chemicals.
- Pick the right fit: push-on, snap-on, ribbed push-in, or threaded protectors.
- Match the look: color, gloss, and dome height for visible installations.
- Plan quantity: bulk packs cut cost for large jobs.

Installation is fast—most press or snap into place by hand and remove just as easily. Many styles are reusable, RoHS-compliant, and available in multipacks. Whether you’re finishing furniture, safeguarding machinery, outfitting vehicles, or organizing fixtures, end caps and screw protectors deliver safety, durability, and a clean finish that lasts.
