Steel Nonmarring Locknuts with Spring-Lock Washer
These locknuts have a curved washer that acts as a spring to add tension between the nut and the material surface for easy installation and mild vibration resistance. The smooth rim makes them less likely to scratch materials when tightened than locknuts with a tooth lock washer. Also known as Keps and K-lock nuts.
Black-oxide locknuts are mildly corrosion resistant and have a dark surface color.
Zinc-plated locknuts have an outer layer of zinc that provides corrosion resistance in wet environments.
