Heavy Duty Flat Washers

Heavy duty flat washers made from heavy pattern steel with a zinc plated finish. They sit under a nut or bolt head and spread the fastener's load over a wider area, which helps protect the surface of the material being fixed.

They are built for demanding fastening jobs and resist compression, shearing, bending and cracking. They are used across engineering, manufacturing, maintenance and repair work. Metric sizes run from 5mm to 20mm and imperial sizes from 3/16 to 1", with pack quantities varying by size.
