Professional Applications & Engineering Value
This M14 tab lock washer delivers critical vibration-resistant performance for demanding industrial applications where fastener security is paramount. Engineered to DIN 432 specifications, the precision-formed tab creates positive locking action that prevents rotational loosening in automotive assemblies, heavy machinery, and power transmission systems. The steel construction with Rockwell B50 hardness ensures consistent performance under cyclic loading, while the metric dimensions (15mm ID, 33mm OD) provide exact compatibility with standard M14 fasteners. This vibration resistant washer solves the critical engineering challenge of maintaining joint integrity in high-vibration environments, reducing maintenance frequency and preventing equipment failure.
Specification Summary & Compliance
Manufactured to DIN 432 standards with precise dimensional tolerances including 15mm internal diameter, 33mm outer diameter, and 1.2mm thickness. The tab lock washer features 4.5mm tab width and 4.5mm overall height for consistent locking performance. Material certification includes Rockwell B50 hardness testing. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and unrestricted industrial use across global markets.
