Acorn & Cap Nuts
Acorn nuts, also referred to as cap nuts, fit snugly onto screws and bolts, protecting them from stripping and providing a more finished look to the fastener. Acorn nuts or rivet nuts can be stainless steel, carbon steel, nickel plated, chrome plated, zinc plated, plastic, brass or nylon and come in a variety of sizes and styles. Caps can also be used on both ends of threaded rods or threaded studs for added protection. Find hex nuts and more nut fasteners at Zoro.com.
