Professional Applications & Engineering Value

This M16 tab lock washer delivers critical vibration resistance in demanding mechanical assemblies where fastener security is paramount. Manufactured from 316 stainless steel, it provides exceptional corrosion resistance against chemicals, moisture, and salt spray, making it suitable for marine, chemical processing, and food industry applications. The DIN 432 compliant tab lock design creates a mechanical interference that prevents nuts and bolts from loosening under dynamic loads, eliminating the need for additional locking mechanisms. With its metric dimensions (17mm ID x 36mm OD), this locking washer ensures perfect compatibility with M16 fasteners while the 1.2mm thickness maintains structural integrity without adding excessive bulk to assemblies.

Specification Summary & Compliance

This tab lock washer features precise metric dimensions with 17mm internal diameter, 36mm outer diameter, and 1.2mm thickness, manufactured to DIN 432 standards for dimensional accuracy and performance reliability. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant (including 233 SVHCs as of 01/17/2023), meeting stringent environmental regulations for industrial components. Designed specifically for M16 screw sizes with a tab width of 5.5mm and overall height of 4.5mm, this washer delivers consistent locking performance across mechanical fastening applications.
