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.
Zinc- and zinc yellow-chromate plated steel washers are corrosion resistant in wet environments.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards.

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.
Steel washers are known for their strength. They're zinc yellow-chromate plated for corrosion resistance in wet environments.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards. Steel washers also meet standards for material properties.
