Professional Applications & Engineering Value
Engineered for demanding environments, these 316 stainless steel flat washers deliver exceptional performance where ordinary fasteners fail. The molybdenum-enhanced alloy provides superior resistance to chlorides and acidic conditions, making them ideal for chemical processing, marine equipment, and food processing machinery. Their ASME B18.21.1 compliance ensures precise dimensional control for reliable seating and uniform load distribution across 1/2" screw connections. The generous 1.75" OD creates an optimal bearing surface that prevents embedment in soft materials and distributes clamping forces effectively, solving common issues of joint loosening and material damage in heavy-duty assemblies.
Specification Summary & Compliance
These inch-system flat washers maintain precise dimensional tolerances with 0.531" ID, 1.75" OD, and thickness ranging 0.090-0.112". Manufactured in strict accordance with ASME B18.21.1 specifications for dimensional consistency and performance reliability. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance control for industrial applications worldwide.
