General:
Lock washer in line with DIN 25201 to prevent loosening in laterally loaded connections, vibrating screw connections and screw connections subject to oscillations.
Corrosion resistance:
600 h base metal corrosion in line with DIN EN ISO 9227-NSS (DIN 50021-SS) — in comparison: 96 h yellow galvanised (A2C)
Function:
The wedge surface slope between the two lock washers ensures highly secure locking. The screw connection is locked by pre-tension instead of by friction.
Benefits:
- Easy to assemble and disassemble (wedge lock washers are already glued in pairs)
- Tested system for screw retainer (locking elements that prevent unscrewing), at high as well as low tension
- Especially suited for dynamic loading – even when used with lubricants
- Can be reused multiple times, without loss of quality
- Gentle on surfaces
- Can also be used with high-strength screws 8.8, 10.9 and 12.9 and the matching nuts
- Available in stainless steel or steel (other materials available on request)
- With narrow and wide contact surface
For the recommended tightening torques, please see the technical information in the DIN/ISO catalogue.
