Toothed Washers

SKU: WSR28 Categories: ,

Toothed washers can have external or internal teeth, or both, and can be provided as countersunk to order.

A toothed washer with external teeth holds teeth that are twisted to grip and extend radially outwards, to bite into the bearing surface – and is effective as a lock washer when used with soft substrates like aluminium or plastic.

A toothed washer with internal teeth has teeth that extend radially inward to bite into the bearing surface – and the internal serration makes the washer look more aesthetically pleasing.

There is also a countersunk toothed washer, which is designed to be used with countersunk screws in a countersunk hole – assisting with locking in the screw.

Should your application require it, we can also supply a toothed internal external combined washer which has teeth around both edges. The teeth are twisted to grip and extend radially inward and outward for maximum holding power.

Available in a range of sizes and materials, with specials made to order.

Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and bespoke parts made to drawings. Minimum order quantities apply.
