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 line 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.
Benefits:
- Easy to assemble and disassemble (wedge lock washers are already glued in pairs)
- 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
- 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 narrow and wide contact surface
