Lock Washers

These External Tooth Lock Washers have been developed for locking screws, bolts and nuts in place, and offer ideal prevention for the loosening of PCB spacers caused by vibrations. The. Our stainless steel toothed washers offer good corrosion and wear resistance.

Internal Tooth Washers are another type locking washer with a series of teeth formed on the inside of the hole. This type of lock washer is generally lighter in cross section and thickness than its counterpart the spring washer. They are available in grade 304 and metric range.

This type of washer is especially effective as a lock washer when used with a soft substrate, such as aluminum or plastic,[8] and can resist rotation more than a plain washer on hard surfaces, as the tension between the washer and the surface is applied over a much smaller area (the teeth).
