Professional Applications & Engineering Value
This M24 zinc plated steel flat washer delivers critical engineering solutions for industrial applications requiring reliable load distribution and corrosion protection. The zinc plated steel construction provides essential galvanic protection against environmental degradation, while the precisely calculated 44mm outer diameter effectively disperses clamping force to prevent surface indentation and maintain structural integrity. Engineered to DIN 125 and ISO 7089 standards, this metric flat washer ensures perfect compatibility with M24 fasteners in heavy machinery, structural steel connections, and industrial equipment assemblies. The combination of Rockwell C30 hardness and controlled thickness tolerance (3.7-4.3mm) delivers consistent performance in high-vibration environments, making it ideal for automotive, construction, and manufacturing applications where fastener reliability is paramount.
Specification Summary & Compliance
This flat washer features precise metric dimensions with 25mm inner diameter and 44mm outer diameter, manufactured within strict thickness tolerances of 3.7-4.3mm. The product conforms to DIN 125 and ISO 7089 international standards for dimensional accuracy and performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory acceptance for industrial applications across global markets.
