Professional Applications & Engineering Value

These titanium SAE flat washers deliver critical engineering solutions where corrosion resistance and weight reduction are paramount. The titanium material grade prevents degradation in chemical processing, marine, and aerospace applications where steel washers would rapidly fail. The ASME B18.21.1 compliant design ensures precise dimensional stability under No. 10 screw heads, eliminating loosening from vibration while maintaining surface integrity. With their 0.219" ID x 0.5" OD dimensions and controlled thickness variation, these washers provide consistent load distribution across fastened joints, preventing surface damage and extending component life in high-stress industrial assemblies.

Specification Summary & Compliance

Manufactured to ASME B18.21.1 dimensional standards with precise inch system measurements: 0.219" internal diameter, 0.500" outer diameter, and thickness ranging 0.036-0.065" for No. 10 screw size applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restriction of hazardous substances. Titanium construction provides inherent material advantages without additional surface treatment requirements for most corrosive environments.
