Professional Applications & Engineering Value

These 316 stainless steel flat washers deliver exceptional engineering value in applications where corrosion resistance is paramount. The inch-system washers with precise 0.344" ID are engineered specifically for 5/16" screws, providing optimal load distribution and preventing surface damage in assembled components. The marine-grade 316 stainless steel composition offers superior performance in saltwater environments, chemical processing plants, and outdoor applications where moisture and corrosive elements are constant challenges. The consistent 0.75" OD and controlled thickness range ensure uniform pressure distribution, reducing stress concentration and extending the service life of both the fastener and assembled materials. These industrial washers solve critical engineering pain points by maintaining structural integrity in aggressive environments where ordinary fasteners would rapidly deteriorate.

Specification Summary & Compliance

These flat washers feature precise dimensional specifications including 0.344" inner diameter, 0.75" outer diameter, and thickness ranging 0.043-0.057" for compatibility with 5/16" screw sizes. Manufactured to standard inch system specifications, these components are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet the latest environmental and safety standards for industrial applications worldwide.
