Ring lock washer in line with DIN 25201 to prevent loosening in laterally loaded connections, vibrating screw connections and screw connections subject to oscillations.
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.
- 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
- Gentle on surfaces
- No risk of incorrect mounting with multi-usage
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.
