Professional Applications & Engineering Value
These SAE flat washers deliver critical engineering value through their steel material composition and precise dimensional control. The 0.141" ID provides exact clearance for No. 5 screws, preventing thread damage during installation while the 0.281" OD creates an optimal bearing surface to distribute clamping forces. This combination solves common assembly challenges including surface marring, joint relaxation, and uneven load distribution. The flat washer design serves as an essential component in industrial machinery, automotive assemblies, and electrical enclosures where reliable fastening is paramount. Their compliance with international standards makes them suitable for export-oriented manufacturing and regulated industries requiring documented material safety.
Specification Summary & Compliance
Manufactured to SAE standards with inch-system dimensions: 0.141" inner diameter, 0.281" outer diameter, and thickness ranging 0.020-0.040". These steel flat washers are engineered for compatibility with No. 5 screw sizes. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures adherence to international environmental and safety standards for industrial components.
