Professional Applications & Engineering Value

This M16 brass flat washer is engineered to solve critical challenges in industrial settings where corrosion resistance and reliable fastening are paramount. The copper alloy construction inherently resists rust and galvanic corrosion, making it ideal for marine, chemical processing, and outdoor infrastructure applications. Its Rockwell B76 hardness ensures the washer maintains its shape under high clamping loads, preventing embedding into softer materials and preserving joint integrity. By conforming to DIN 433 and ISO 7092 standards, it guarantees dimensional precision and interchangeability in global machinery and assembly lines, reducing downtime and replacement costs. The precise 16mm internal diameter and 28mm outer diameter provide an optimal bearing surface, effectively distributing pressure and protecting components from damage in heavy-duty industrial washers applications.

Specification Summary & Compliance

This washer features a 16 mm ID, 28 mm OD, and a controlled thickness of 2.3-2.7 mm for M16 screw sizes. It is manufactured from brass with a hardness of Rockwell B76 and complies with the dimensional and technical requirements of DIN 433 and ISO 7092 standards.
