General Purpose Washers
Use these washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.
18-8 stainless steel and 17-7 PH stainless steel washers have good chemical resistance and may be mildly magnetic.

Internal-Tooth Lock Washers
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.
400 series stainless steel washers have excellent wear resistance, but aren’t as corrosion resistant as other stainless steel washers. They may be mildly magnetic.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards.
