General information:
Lock washer as per DIN 25201, prevents screw connections from loosening when faced with lateral stress, shocks, or vibration.
Corrosion resistance:
600 hours of base metal corrosion as per DIN EN ISO 9227-NSS (DIN 50021-SS) – cf.: 96 hours, yellow zinc plated (A2C)
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)
- Tested system for screw locking (locking elements prevent screw from opening) at high and low pre-tension
- Particularly well suited for dynamic load – even with lubricants
- Reusable with consistent quality
- Does not harm surfaces
- Also usable with strong hardness class 8.8, 10.9, and 12.9 screws and corresponding nuts
- Available in stainless and regular steel (other materials available on request)
- Available with narrow and wide contact area
In screw-to-nut connections the serrated lock washer pair must be used below both the screw head and the nut. Torque recommendations are laid out in DIN/ISO list specifications.
