Professional Applications & Engineering Value

These 316 stainless steel flat washers deliver exceptional engineering value in demanding applications where corrosion resistance is critical. The marine-grade 316 stainless steel composition provides superior protection against saltwater, chemicals, and industrial atmospheres that would rapidly degrade standard washers. With precise inch system dimensions (0.281" ID x 1.5" OD), these flat washers ensure perfect fitment for 1/4" screw applications while the generous outer diameter distributes clamping forces effectively across joined surfaces. This combination of corrosion-resistant material properties and dimensional accuracy makes them ideal for marine equipment, chemical processing plants, food processing machinery, and offshore installations where fastener failure is not an option.

Specification Summary & Compliance

Manufactured to precise inch system specifications with internal diameter of 0.281", outer diameter of 1.5", and thickness range of 0.052-0.072" for consistent performance in 1/4" screw applications. These flat washers comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and material safety. The 316 stainless steel construction provides inherent corrosion resistance without additional surface treatments, maintaining dimensional stability across varying environmental conditions.
