Metric All Metal Lock Nuts (DIN 980V), Class 10 Yellow Zinc

METRIC CLASS 10 ALL METAL LOCKNUT, DIN 980 V, ZINC YELLOW CR+6 & WAX

Metric lock nuts have a "locking" element that prevents the nuts from free spinning after the element engages the mating threads. For metric all metal lock nuts, thread deformation creates the prevailing torque, which may cause thread galling. Reuse is limited since the prevailing torque declines each time the nut is installed and removed.
