Professional Applications & Engineering Value
These titanium SAE flat washers deliver critical engineering advantages where corrosion resistance and weight reduction are paramount. The titanium material grade provides exceptional performance in chemical processing, marine, and aerospace applications where standard steel washers would rapidly deteriorate. The ASME B18.21.1 compliance ensures precise dimensional stability and reliable performance in high-vibration environments. With their inch system measurement and exact 5/16" screw compatibility, these flat washers prevent loosening and distribute loads evenly across mating surfaces. The combination of lightweight properties and environmental compliance makes them ideal for industries requiring both technical performance and regulatory adherence.
Specification Summary & Compliance
Manufactured to ASME B18.21.1 standards with precise dimensional tolerances, these titanium washers feature 0.344" inner diameter and 0.688" outer diameter with thickness ranging 0.051-0.080". The inch system measurement ensures compatibility with standard 5/16" fasteners. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and restricted substance adherence for global industrial applications.
