General:
Lock washer in accordance with DIN 25201 to prevent loosening in laterally loaded and vibrating screw connections and screw connections subject to oscillations.
Corrosion resistance:
600 h base metal corrosion in accordance with DIN EN ISO 9227-NSS (DIN 50021-SS) - in comparison: 96 h yellow zinc plated (A2C)
Function:
Highly secure locking as wedge surfaces slope up between the two lock washers. The screw connection is locked by pretension instead of by friction.
Advantages:
- Easy to install and remove (wedge lock washers are already bonded in pairs)
- Tested system for threadlocker (locking elements that prevent unscrewing), at high as well as low tension
- Especially suitable for dynamic loading - including when lubricants are used
- Can be reused multiple times without loss of quality
- Protects surfaces
- Can also be used with high-strength screws 8.8, 10.9 and 12.9 and the corresponding nuts
- Available in stainless steel or steel (other materials available on request)
- With a narrow and a wide contact surface
For screw-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.
