General:
Lock washer in line with DIN 25201 to prevent loosening in laterally loaded connections, vibrating screw connections and screw connections subject to oscillations.
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
- Available in stainless steel or steel (other materials available on request)
- With narrow and wide contact surface
For bolt-nut connections, a pair of wedge lock washers must be used both under the screw head and under the nut. For the recommended tightening torques, please see the technical information in the DIN/ISO catalogue.
