Collection: Through Hardened Washers
Through hardened washers are hardened all the way through, so they do not dish or bed in under the high clamping force of high tensile bolts. They are used under the nut or bolt head on structural steelwork and heavily loaded machinery.
Our range runs from M6 to M56, zinc plated or bare, with stainless options.
Pair them with High Tensile Hex Head Bolts and Hex Nuts.
