Professional Applications & Engineering Value
This M16 flat washer excels in demanding settings where precision and reliability are non-negotiable. Crafted from 18-8 stainless steel, it combats rust and chemical exposure in industries like marine, food processing, and chemical plants. The DIN 9021 standard ensures tight tolerances and uniform thickness (2.7-3.3mm), preventing loosening from vibrations and distributing clamp load effectively to protect surfaces. Its metric dimensions (17mm ID, 50mm OD) and Rockwell B52 hardness make it a go-to for heavy-duty bolting in structural frameworks, automotive engines, and industrial equipment, reducing maintenance downtime and enhancing assembly integrity.
Specification Summary & Compliance
This flat washer adheres to DIN 9021 specifications with precise metric dimensions: 17mm inner diameter, 50mm outer diameter, and 2.7-3.3mm thickness for M16 screw sizes. It meets Rockwell B52 hardness standards for consistent mechanical performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial supply chains.
