5/16"-24 Cap Nut, Chrome Plated Finish, Brass Not Graded, PK10
Use an acorn nut to protect and give a finished look to an exposed bolt end. It can help prevent stripping of screws and bolts on engines, machinery, and wood frames so they can be easily removed and reused. With brass construction, this acorn nut resists rust and moderate atmospheric corrosion. The copper-zinc alloy is durable, and also conducts electricity. Nonmagnetic.
