Two Way Reversible Lock Nuts

Two Way Reversible Locknuts

Two Way Reversible Locknuts are available in steel with a zinc, black oxide or black zinc finish; and also in 18-8 stainless steel. Featuring a round or rectangular indentation on the outer hex which slightly distort the center threads, two way reversible locknuts allow for a locking action even without full engagement of the mating screw.
