Wedge Lock Washer

🔩 Wedge Lock Washer

(High-Security Locking Washer for Critical Bolted Joints Under Extreme Vibration)

Neo Fasteners offers premium-quality Wedge Lock Washers, designed for maximum reliability in high-vibration, dynamic load, and safety-critical applications. These washers use tension-based locking technology rather than friction, making them ideal for bolted joints in industries like railway, automotive, construction, wind energy, heavy equipment, and aerospace.

🔹 Product Overview:

A Wedge Lock Washer consists of two identical washers with wedge-shaped cams on one side and radial serrations on the other. When the bolt is tightened, the serrated faces grip the mating surfaces, and the cam faces face each other, creating a wedge effect that resists self-loosening even under extreme vibration or dynamic loads.
