Hillman 3/8 in. Stainless Steel SAE Acorn Nut 50 pk

Stainless steel acorn cap nuts are hex nuts with a partially internally-threaded dome shape. The dome offers protection of exposed screw threads and a decorative appearance as a finishing fastener. The cap nut also protects the user from injury by covering exposed threads. Parts have a stainless steel finish for best-in-class corrosion resistance. *
