Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 316 stainless steel flat washers provide critical protection against galvanic and chemical corrosion, making them essential for marine equipment, chemical processing plants, and food-grade facilities. The precise 1.562" ID ensures optimal alignment with 1 1/2" screw sizes, while the generous 3" OD distributes clamping force over a wider area, preventing joint loosening and surface indentation. With a 0.100-0.180" thickness range, they accommodate minor dimensional variations in assembled components, solving common tolerance stack-up issues. The RoHS 3 and REACH compliance further ensures these washers meet stringent environmental and safety regulations for global supply chains.
