Cap Nuts

470 products

Use an acorn nut to protect and give a finished look to an exposed bolt end. Cap nuts prevent stripping of screws and bolts on engines, machinery and wood frames so they can be easily removed and reused. Brass nuts are commonly chosen for plumbing and electrical applications. Use acorn nuts from Grainger to protect exposed ends of threaded fasteners indoors and out.
