Hillman 4-Count #10 Brass-Plated Standard (SAE) Cap Nuts

Acorn nuts, also known as cap nuts, add to the durability of a screw. When threaded on a fastener, the nut will hide the threads and provide a nice finished look. These acorn nuts are hex nuts with an enclosed dome that is partially, internally threaded. They offer protection to threads and a decorative appearance as a finishing fastener. Acorn nuts are often used in hobby and furniture projects.
