SS Internal Tooth Lock Washer

Stainless Steel internal tooth lock washers are used under bolt heads or nuts to increase the hold of the fastener. They can be manufactured of 18-8 or 400 series stainless steel. Internal tooth lock washers have teeth on the inner dimension of the washer creating a ratchet action by biting into the nut or screw head and the surface it contacts. Dimensional specifications are governed by ASME B18.21.1. Stainless steel fasteners are commonly used in applications that require general atmospheric corrosion resistance, such as chemical and food processing equipment.
