Professional Applications & Engineering Value

These SAE flat washers manufactured from zinc-plated steel provide critical engineering solutions for industrial applications where vibration resistance and surface protection are paramount. The precise 0.219" inner diameter ensures perfect fitment with No. 10 screws, while the 0.5" outer diameter creates an optimal bearing surface that distributes clamping forces evenly across assembled components. This design prevents embedding, reduces stress concentration, and maintains bolt preload in mechanical systems subject to dynamic loads. The flat washer configuration serves as an essential interface between fastening elements and workpiece surfaces, protecting sensitive materials from damage during torque application and preventing galvanic corrosion in mixed-material assemblies. Engineered to ASME B18.21.1 standards, these washers deliver consistent performance in automotive, machinery, and structural applications where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to exacting dimensional standards with inner diameter of 0.219", outer diameter of 0.5", and thickness ranging from 0.036" to 0.065". These SAE flat washers conform to ASME B18.21.1 specifications for inch-series flat washers, ensuring proper fit and function with No. 10 screw sizes. The products maintain full compliance with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) standards regarding substance restrictions and environmental safety, making them suitable for global industrial supply chains and environmentally conscious manufacturing operations.
