Serrated Flange Hex Lock Nuts Case Hardened HR15N 78/90 Zinc

Requires a greater amount of torque to loosen than to tighten the nut. Will span oversized or poorly aligned holes. Flange provides a more uniform bearing-stress to clamp-force ratio than other low carbon lock nuts. Does not gall screw threads.
