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.
K500 nickel washers (also known as Monel) have excellent resistance to salt water and some acids. They may be mildly magnetic.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards.
