Quick Lock Washer
Quick Lock Washers are advanced locking elements designed with wedge-locking action to prevent loosening of bolted joints under vibration or shock. They are manufactured to ASTM, DIN, and ISO standards in hardened steel, alloy steel, or stainless steel. The dual-washer design creates opposing wedge angles with serrated surfaces, ensuring the bolt remains secure even under extreme dynamic loads. Available with zinc flake, stainless, or black oxide finishes, they provide high corrosion resistance and long service life. They are widely used in railways, wind turbines, heavy machinery, automotive, and critical safety applications where bolt loosening is unacceptable.
