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.
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.
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
- Can also be used with high-strength screw connections 8.8, 10.9 and 12.9
- 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.
