Due to the recent Covid-19 outbreak, our trade counter is currently closed for customers.

Collection is available on orders with instructions for collections once orders are placed.

Courier deliveries are currently operating as normal with some delays in a small select number of locations.

We have made arrangements with suppliers to send items direct on a next day service on items that have a 3 day availability and are not on our shelves. These charges are set by our manufacturers and will depend on items ordered and delivery postcode, but should help with clearing backlogs and ensuring deliveries are received quickly if required.

This information may change at any time.

Internal Toothlock Washers Stainless Steel

Internal Toothlock Washers Stainless Steel

These washers with serrations are designed to bite into the bearing surface.  These are especially effective when used with soft materials such as aluminium or plastic. 


Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high salinity, or poor air-circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties or steel and corrosion resistance are required.
