Professional Applications & Engineering Value
This DIN 432 tab lock washer in 316 stainless steel provides critical vibration-resistant fastening solutions for demanding industrial applications. The unique tab locking mechanism actively prevents rotational loosening in M5 fastener systems subjected to constant vibration and thermal cycling. Engineered with precise metric dimensions (5.3mm ID, 17mm OD), it ensures proper seating and uniform load distribution across mating surfaces. The 316 stainless steel material offers superior resistance to chemical corrosion and extreme temperatures, making it ideal for marine, chemical processing, and food industry applications where reliability is paramount. The tab lock design eliminates the need for additional locking components, streamlining assembly while maintaining secure fastening integrity in high-vibration environments.
Specification Summary & Compliance
Manufactured to DIN 432 standards with precise metric dimensions: 5.3mm inner diameter, 17mm outer diameter, and 0.75mm thickness. The tab width measures 3.5mm with overall height of 2.5mm, specifically designed for M5 screw applications. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance. The 316 stainless steel construction provides consistent performance without hardness rating requirements for general industrial use.
