Professional Applications & Engineering Value

These 316 stainless steel flat washers deliver critical protection in demanding settings where moisture, chemicals, or salt exposure threaten fastener integrity. The inch system flat washer design, with its 0.344" ID and 0.75" OD, ensures optimal surface contact and stress dispersion for 5/16" screw assemblies. Engineers specify them for marine equipment, chemical processing plants, and outdoor structures to prevent galvanic corrosion and distribute clamping forces evenly. The controlled 0.170-0.200" thickness provides consistent performance in gasketing, vibration dampening, and electrical isolation tasks, reducing assembly failures and extending service life in industrial washers applications.

Specification Summary & Compliance

This flat washer adheres to inch system standards with ID 0.344", OD 0.75", and thickness tolerance 0.170-0.200" for #5/16 screw sizes. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring hazardous substance restrictions are met for safe industrial use.
