Serrated Lock Washer

Introduction

DIN-6796, 2093, 9250

Washers are used to seal cable glands to prevent water and other substances getting inside, but they can also be used to stop components shaking loose. That is where serrated washers come in. Serrated washers help to prevent vibration and subsequent loosening.

Serrated Lock Washer

The advantages of Serrated Safety Washers are :
  • Used for high vibration resistance due to positive rib contact.
  • Excellent Pretensioning.
  • Through proper radius selection, no splitting/cracking occurs during tightening.
  • The concentric force of the washer eliminates the chances of bending the fastener.
  • Extensive application and flexibility, minimizes stocks.
