A cap nut from Grainger offers protection and a finished look to the exposed end of a threaded nut, bolt or stud. Sometimes called push nuts, cap nuts hold the studs, nuts or bolts in place and provide a more aesthetic look. Choose the size you need in plastic, zinc-plated steel and steel with nickel finish. Also find nylon license plate nuts here. Shop Grainger today for the cap nut or push nut you need!
