Split Lock Washers
As a screw is tightened, these washers flatten to add tension to the joint and prevent loosening from small amounts of vibration.
316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
Zinc- and zinc yellow-chromate plated steel washers are corrosion resistant in wet environments.
Bronze washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards. Steel washers also meet standards for material properties.

Oversized Split Lock Washers
Compared to standard split lock washers, these are thicker and have larger outside diameters. As a screw is tightened, they flatten to add tension to the joint and prevent loosening from small amounts of vibration.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards.

Shims for Keyway Broaches
When broaching in multiple passes, shims are necessary to ensure full keyway depth. Slide them between the broach and bushing to set the depth of the keyway.
Note: Broaches have a style designation of A, B, B1, C, C1, D, D1, or E. For proper fit, broaches, bushings, and shims used together must have the same letter designation.
