Professional Applications & Engineering Value
This Grade 9 SAE flat washer delivers critical engineering value in heavy machinery, construction, and automotive assemblies where vibration resistance and load stability are paramount. The zinc yellow-chromate plated steel construction combats corrosion in outdoor or chemically aggressive settings, while the precise SAE inch dimensions ensure optimal fit with 1 1/8" fasteners. Its Rockwell C43 hardness prevents embedding and maintains clamp force under dynamic stresses, solving common issues of joint failure and maintenance downtime. Ideal for industrial applications demanding high-strength flat washers that meet rigorous performance and compliance standards.
Specification Summary & Compliance
Manufactured to SAE standards with exacting dimensional tolerances, this washer features a 1.181" inner diameter, 1.993" outer diameter, and controlled thickness range of 0.234-0.266" for consistent performance. It complies with Grade 9 strength classification and is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring adherence to environmental and safety regulations for industrial use.
