Plastic Hex Caps

Plastic hex head caps are protective covers that snap over the head of a hex nut or bolt, concealing sharp edges, preventing corrosion of the fastener head, and giving a clean, finished look to exposed fixings. Available in black and white in M8 and M10 sizes, sold in packs of 100.

Made from heavy-gauge PVC plastic, these caps fit snugly over the hex head and are UV-resistant for outdoor use. Commonly used in construction, cladding, roofing, and anywhere fastener heads are visible and need a neat finish.

  • Material: Heavy gauge PVC plastic
