Professional Applications & Engineering Value

This M10 metric steel tab lock washer addresses critical vibration-induced loosening challenges in industrial machinery, automotive assemblies, and heavy equipment. The DIN 432 certified design features a precisely formed tab that engages with the nut or bolt head, creating mechanical interference that resists rotational movement. Manufactured from steel with Rockwell B50 hardness, this washer maintains its locking properties through repeated stress cycles without deformation. The 1mm thickness and 4mm overall height provide optimal spring action while fitting within tight clearance spaces. Ideal for vibration-resistant fastening in motors, pumps, and structural connections where safety and reliability are paramount, this component delivers engineered security without requiring additional locking compounds or complex installation procedures.

Specification Summary & Compliance

This tab lock washer features precise dimensional specifications including 10.5mm inner diameter, 26mm outer diameter, 1mm thickness, and 4.5mm tab width, engineered to DIN 432 standards for consistent performance. The manufacturing process ensures proper Rockwell B50 hardness for optimal spring characteristics and durability. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility and material safety. Designed specifically for M10 screw sizes in metric fastening systems, this component meets international quality requirements for industrial applications demanding reliable anti-loosening performance.
