Professional Applications & Engineering Value
Engineered for demanding industrial applications, these Bumax 109 stainless steel flat washers deliver critical performance where corrosion resistance and mechanical strength are paramount. The M10 metric sizing and adherence to DIN 125 and ISO 7089 standards ensure precise compatibility in machinery, automotive, and construction assemblies. The Rockwell C30 hardness provides excellent resistance to deformation under load, while the stainless steel material prevents rust in humid or chemical-exposed environments. These washers effectively distribute clamping force, reduce friction, and prevent bolt loosening due to vibration, making them essential for heavy-duty fastening systems requiring long-term reliability and minimal maintenance.
Specification Summary & Compliance
This flat washer features an internal diameter of 10.5mm, outer diameter of 20mm, and thickness range of 1.8-2.2mm, manufactured to DIN 125 and ISO 7089 dimensional standards for metric M10 screw applications. Material specifications include Bumax 109 stainless steel with a hardness of Rockwell C30. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial use.
