About Washers

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-aluminum-coated steel washers are 40 times as corrosion resistant as zinc-plated washers and comparable to Magni-coated washers.
Aluminum washers are lightweight and corrosion resistant in wet environments.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards.
