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.
