Wedge lock washer with assortment of narrow/wide types 500 pieces in system case 4.4.1.

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
