Professional Applications & Engineering Value
These SAE flat washers provide critical engineering solutions where corrosion resistance and dimensional precision are paramount. The black corrosion-resistant coating on steel substrate offers superior protection against environmental degradation, significantly extending service life in industrial settings exposed to moisture, chemicals, or outdoor conditions. Engineered specifically for No. 10 screws with precise 0.219" ID and 0.5" OD dimensions, these flat washers ensure optimal load distribution, preventing surface damage, reducing stress concentrations, and maintaining bolt preload in mechanical assemblies. The compliance with ASME B18.21.1 standards guarantees consistent quality and performance across manufacturing, maintenance, and repair operations in automotive, machinery, and structural applications.
Specification Summary & Compliance
This SAE flat washer features precise inch-system dimensions with 0.219" inner diameter, 0.5" outer diameter, and thickness ranging 0.036-0.065". Manufactured to ASME B18.21.1 specifications for dimensional accuracy and performance consistency. The product is fully compliant with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) requirements, meeting environmental standards for industrial use while maintaining the durability expected from corrosion-resistant coated steel construction.
