General:
Lock washer in accordance with DIN 25201 to prevent loosening in laterally loaded and vibrating screw connections, and screw connections subject to oscillations.
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 assemble and disassemble (wedge lock washers are already glued 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
- With a narrow and a wide contact surface
