Screw caps​ and covers

Screw caps and covers are used to conceal and protect exposed screw heads in a range of situations, on both inside and outside jobs. They help reduce the risk of corrosion and create a clean finish for fixtures, furniture, and cladding. Many builders use them in joinery, electrical work, and light commercial fit-outs, especially where visible fixings need to be low profile.

Options include snap-on and push-fit screw caps, hinge-top designs, and low-profile screw covers for recessed or flush screw heads. Most are plastic, available in common colours like white and black to blend with surrounding surfaces. Modern screw cap types offer quicker fitting and improved fit compared to older glued or threaded versions.
