Our M8 Stainless Steel External Tooth Serrated Washer DIN 6797A is a premium fastening solution designed to lock components securely in place and prevent loosening under vibration, thermal changes, or movement. These M8 shake proof washers are most commonly paired with bolts, machine screws and nuts to ensure a stable and secure assembly in a variety of industrial applications.

This product has a series of serrated teeth positioned around the outer edge that grip the surface material when compressed. Manufactured from high-grade A2 (304) Stainless Steel, these washers provide excellent corrosion resistance, mechanical strength and reliability in medium to heavy-duty applications. Available in metric sizes from M2 to M30, they are designed for use with externally threaded fasteners across a wide range of projects and environments.

What are External Tooth Serrated Washers?

M8 External Tooth Serrated Washers are locking washers produced to the DIN 6797A standard. Their external teeth are designed to dig into the bearing surface of the component and the underside of the fastener head during tightening. This creates a locking action that helps prevent loosening caused by vibration, rotation, or thermal expansion. Unlike internal toothed variants, external tooth washers provide a larger gripping surface area and are especially suited to flat-head or round-head fasteners.
