General information:


Lock washer as per DIN 25201, prevents screw connections from loosening when faced with lateral stress, shocks, or vibration.



Operation:


Two serrated lock washers combine in a wedge fashion, ensuring an extremely durable hold. The screw connection is held fast by pre-tension instead of friction.



Benefits:


  • Easy assembly and disassembly (serrated lock washers come pre-glued into pairs)

  • Locking with screws tested (locking elements prevent screw from opening) with both high and low pre-tension

  • Particularly well suited for dynamic load – even with lubricants

  • Reusable with consistent quality

  • Does not harm surfaces

  • Available in stainless and regular steel (other materials available on request)

  • Available with narrow and wide contact area
Notice

Torque recommendations are laid out in DIN/ISO list specifications.
