Details

Also known as plain washers, their purpose is to distribute the fastener's load while reducing heat and friction during the tightening process. They can also be used as spacers. Form B: Normal diameter, light thickness. Stainless steel is a family of iron-based alloys that contain a minimum of approximately 11% chromium, a composition that prevents the iron from rusting, as well as providing heat-resistant properties.
