Professional Applications & Engineering Value

This M10 metric flat washer delivers critical engineering solutions through its zinc-plated steel composition and DIN 440-R compliance. The corrosion-resistant surface treatment combats rust in demanding settings like manufacturing plants or outdoor installations, while the 11mm ID/34mm OD dimensions ensure uniform load dispersion to prevent bolt loosening or joint failure. Ideal for industrial machinery, structural frameworks, and automotive assemblies, it addresses common pain points like galvanic corrosion, vibration-induced wear, and regulatory non-compliance. By adhering to stringent DIN standards, this washer provides predictable performance, reduces maintenance cycles, and supports efficient metric hardware integration in global supply chains.

Specification Summary & Compliance

Manufactured to DIN 440-R standards with precise inner diameter (11mm), outer diameter (34mm), and thickness (2.4–3.6mm) tolerances for M10 screw compatibility. The zinc-plated steel construction meets industrial hardness requirements, while full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and unrestricted international procurement.
