Spring Washers

Steel spring washers with a Bright Zinc Plated (BZP) finish. They fit under a nut or bolt head and stop the fastener working loose. When compressed, the washer applies a spring force that keeps tension in the joint. This holds fasteners in place under vibration or dynamic loading.

They suit machinery, vehicles and equipment that are always moving or vibrating, and they also take up shock within the fastening assembly. The BZP finish gives corrosion resistance and helps guard against bimetallic corrosion, so they work across general engineering and maintenance jobs.
