Professional Applications & Engineering Value
This M5 zinc plated steel flat washer delivers critical engineering solutions where vibration resistance and surface protection are paramount. The zinc plating creates a protective barrier against oxidation, significantly extending component life in mechanical systems exposed to humidity or chemicals. Manufactured to DIN 125 and ISO 7089 specifications, these metric flat washers ensure perfect compatibility with M5 fasteners in automotive assemblies, electrical enclosures, and machinery frames. The Rockwell B75 hardness prevents deformation under torque loads, while the precise dimensions eliminate play in bolted joints. Ideal for industrial washers applications requiring RoHS and REACH compliant components, they provide reliable performance in regulated industries without compromising on durability.
Specification Summary & Compliance
This flat washer features 5.3mm internal diameter and 10mm outer diameter with thickness between 0.9-1.1mm, engineered for M5 screw applications. Manufactured according to DIN 125 and ISO 7089 standards for dimensional accuracy and performance. The zinc plated steel construction provides Rockwell B75 hardness rating. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory acceptance for industrial use.
