Professional Applications & Engineering Value
These wedge lock washers are engineered to solve critical vibration-induced loosening problems in demanding industrial environments. The black zinc-flake-coated steel construction provides superior corrosion resistance while maintaining structural integrity. The dual-sided serrations create multiple biting surfaces that dig into both the fastener and mating surface, generating exceptional clamping force that withstands extreme dynamic loads. Ideal for heavy machinery, automotive assemblies, construction equipment, and manufacturing systems where vibration resistance is paramount. The Rockwell C48 hardness ensures the washers maintain their locking capability through repeated stress cycles without deforming, making them a reliable solution for critical connections in inch-system applications.
Specification Summary & Compliance
This wedge lock washer features precise dimensional specifications with 0.53" inner diameter, 1" outer diameter, and 0.120-0.140" thickness range, designed specifically for 1/2" screw applications in the inch measurement system. The washers are manufactured from steel with black zinc-flake coating and achieve Rockwell C48 hardness for optimal performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial use worldwide.
