Stover Lock Nut, Hillman, Hex, M16-2.00

Stover lock nuts are one-piece, all-metal prevailing hex nuts with a conical top and flat bottom-bearing surface with chamfered corners. Since they are top-locking and only the bottom surface is flat, stover nuts are considered one-way lock nuts because they can only be installed one way.

• Capable of withstanding severe vibration and shock loads
