Professional Applications & Engineering Value
This M2.5 flat washer is engineered to solve critical challenges in precision assemblies. Its 17-7 PH Stainless Steel composition offers excellent resistance to stress corrosion cracking, a common failure point in demanding environments like aerospace, medical devices, and electronics. The DIN 125 standard ensures perfect compatibility with metric fasteners, eliminating fitment issues. The flat washer design provides a consistent bearing surface, distributing clamp load effectively to prevent damage to soft materials and maintain joint integrity. This makes it an indispensable component for engineers requiring a reliable, corrosion-resistant, and high-strength solution for long-lasting performance.
Specification Summary & Compliance
This washer conforms to the dimensional and tolerance requirements of the DIN 125 standard. Key specifications include an Inside Diameter (ID) of 2.7 mm, Outside Diameter (OD) of 6 mm, and a Thickness of 0.4-0.6 mm, designed for an M2.5 screw. The material is 17-7 PH Stainless Steel with a hardness of Rockwell C40. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
