Professional Applications & Engineering Value

These 316 stainless steel SAE flat washers deliver exceptional value in demanding applications where corrosion resistance is critical. The inch-system dimensions and precise 0.14" ID ensure perfect compatibility with No. 5 screws, while the 0.312" OD provides optimal surface coverage to prevent embedding and distribute clamping forces effectively. The flat washer design according to SAE standards guarantees consistent performance in machinery, marine equipment, chemical processing, and outdoor installations where moisture, chemicals, or salt exposure would degrade ordinary washers. The 316 stainless steel material offers superior protection against pitting and crevice corrosion, making these washers ideal for maintaining structural integrity in challenging industrial environments where reliability cannot be compromised.

Specification Summary & Compliance

This SAE flat washer features inch-system dimensions with 0.14" internal diameter, 0.312" outer diameter, and thickness ranging 0.025-0.040" for No. 5 screw applications. Manufactured to SAE standards using 316 stainless steel, these washers ensure dimensional accuracy and reliable performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components.
