Professional Applications & Engineering Value

This M36 metric flat washer addresses critical engineering challenges in heavy machinery, construction equipment, and industrial assembly applications. The blue-dyed steel material provides not only corrosion resistance but also quick visual identification during installation and maintenance cycles. With its 70mm OD and precise 39.3mm ID, this washer effectively distributes clamping forces across a wider surface area, preventing bolt head embedding and reducing stress concentration on connected components. The Rockwell C38 hardness ensures the washer maintains its structural integrity under extreme vibration and load conditions, making it ideal for applications where fastener reliability is paramount. These industrial washers serve as essential components in structural steel connections, heavy equipment manufacturing, and maintenance operations where consistent performance and regulatory compliance are non-negotiable requirements.

Specification Summary & Compliance

This metric flat washer features precise dimensional specifications including 39.3mm inner diameter, 70mm outer diameter, and 3.9-4.3mm thickness range. Manufactured from blue-dyed steel with Rockwell C38 hardness, it meets industrial standards for heavy-duty washers. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for international industrial applications.
