Plain A4 stainless steel

General:


Ring 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.



Ring lock washer assembly:


The ring lock washers are delivered pre-assembled. The ring lock washer system consists of a polyamide ring (PA) and the wedge lock washers described above.



Benefits:


  • Simple fitting and removal

  • Tested system for screw retainer (locking elements that prevent unscrewing), at high as well as low tension

  • Especially suitable for dynamic loading — including when lubricants are used

  • Reusable

  • Gentle on surfaces

  • No risk of incorrect mounting with multi-usage
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.
