Teeth on the outside edge of the washer bite into the screw head and joint for a tight grip. Use with fasteners that have heads large enough to make contact with the teeth, such as pan, button, and binding head screws.
Bronze washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards.

Internal teeth dig into the screw head while the smooth outside edge won't snag objects. These washers provide greater vibration resistance than split lock washers. Use with fasteners that have small heads, such as fillister and cheese head screws.
