These washers are suitable for spreading clamping load, protecting the surface of the material being fastened and helping to reduce wear under a nut or bolt head.
Zinc plated steel provides general corrosion resistance for indoor and sheltered applications. For outdoor, marine, coastal or highly corrosive environments, stainless steel or galvanised washers may be more suitable.
