Wedge lock washer - effectively secures laterally loaded, vibrating screw connections and screw connections subject to oscillations against self-turning

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
Notice

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.
