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
