Lock Washers

Lock washers are designed to create tight assemblies by providing the required torque to ordinary fasteners. Raptor Supplies offers a wide range of flat washers, lock nuts, split lock washers & spring lock washers from brands like Grainger, Metric Blue, Midwest Acorn Nut, Nord-Lock, Disc-Lock and Armor Coat. Grainger helical-shaped carbon-steel lock washers or split-lock washers are designed to provide a spring action, activated even by the slightest pressure. They are ideal for grabbing adjoining materials to prevent loosening caused by vibration. These units are compatible with 1/2, 5/8, 3/4, 7/8 and 1 inch bolt sizes.
