Made of steel alloy, it exhibits exceptional strength, corrosion resistance, and durability making it ideal for harsh outdoor or chemical environments. Its unique design features a serrated outer washer which is compressed between the nut and the bolt head to create an axial force providing secure locking mechanism without tightening any further, preventing loosening caused by vibration or torque. It's widely used in aerospace, automotive, construction, engineering and other industrial applications where critical components require robust holding solutions with minimal maintenance or downtime. In short, the washer lock nut provides versatile, reliable and economical solution for securing assemblies requiring frequent adjustments or inspection without having to disassemble components.
