DIN 6798 Internal Serrated Lock Washer, Type I

The lock washer, manufactured to DIN 6798, is designed to secure fasteners: bolts, screws, studs, pins and other items. It prevents the connection from loosening, including under vibration loads.

Along the inner diameter of the washer there are protruding teeth that grip the fastener and prevent it from unscrewing. The outer edge of the washer is flat and smooth. The item is selected according to the diameter of the fastener used.

Characteristics and application

DIN 6798 lock washers are made of spring steel with increased elasticity. For improved corrosion resistance, zinc-plated steel is used; stainless acid-resistant steel or bronze are also used. These alloys are resistant to aggressive external conditions, so the products can be used in chemically active environments.

Serrated lock washers have the following characteristics:

• Nominal thread diameter — from M2 to M30.
• Inner hole diameter — from 2.2 to 31 mm.
• Outer diameter — from 4.5 to 48 mm.
