Professional Applications & Engineering Value

These 316 stainless steel SAE flat washers deliver exceptional performance in corrosive industrial settings where standard fasteners fail. The marine-grade 316 composition provides superior resistance to chlorides, acids, and extreme temperatures, making them ideal for chemical processing equipment, marine hardware, and food processing machinery. The precise 0.219" ID ensures perfect alignment with No. 10 screws, while the 0.5" OD distributes clamp load effectively to prevent surface damage and maintain joint integrity. These inch-system washers solve critical challenges in maintenance-heavy industries by offering long-term reliability where corrosion-induced fastener failure would otherwise cause costly downtime and equipment damage.

Specification Summary & Compliance

Manufactured to SAE standards with inch system dimensions: 0.219" internal diameter, 0.5" outer diameter, and thickness ranging 0.036-0.065". These flat washers maintain dimensional accuracy for reliable performance with No. 10 screw sizes. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures adherence to international environmental and safety standards for hazardous substance restrictions.
