Ring lock washer Wide shape

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
