Wedge lock washer - effectively secures laterally loaded, vibrating screw connections and screw connections subject to oscillations against self-loosening
254 SMO® special material is highly resistant to crevice and surface erosion and was specially developed for offshore applications on oil and gas platforms.
Lock washer in accordance with DIN 25201 to prevent loosening in laterally loaded and vibrating screw connections and screw connections subject to oscillations.
Highly secure locking as wedge surfaces slope up between the two lock washers. The screw connection is locked by pretension instead of by friction.
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 installation/removal (wedge lock washers are already glued in pairs)
- Tested system for threadlocker (locking elements that prevent loosening), at high as well as low pretension
- 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
