Description:

Regular: A coiled, hardened, split circular washer with a slightly trapezoidal wire section.

High-Alloy: Dimensionally identical to a regular split lock washer but made from 4037 alloy steel (sizes over 1" are equivalent to heavy split lockwashers in size and material).

Stainless: A regular split lock washer made from austenitic stainless steel.

Advantages:

Regular:

(A) Applies greater bolt tension per unit of applied torque;

(B) Provides a hardened bearing surface, creating more uniform torque control;

(C) Provides more uniform load distribution; (D) Resists loosening caused by vibration and corrosion;
(E) Is preferred lockwasher for use with hardened bearing surfaces.

High-Alloy: Designed for use with Grade-5 & Grade-8 bolts and nuts.

Stainless: For use with stainless nuts and screws of a similar stainless alloy in corrosive environments.
