Professional Applications & Engineering Value
Engineered for demanding industrial environments, these nylon plastic flat washers solve critical challenges in corrosion-prone applications where metal washers would fail. The non-conductive, non-magnetic properties make them ideal for electrical enclosures, food processing equipment, and marine applications. With their excellent chemical resistance and ability to withstand temperature extremes from -40°F to 300°F, these washers maintain dimensional stability in outdoor, automotive, and HVAC systems. The 2" outer diameter provides superior surface coverage while the precise 0.41" inner diameter ensures secure seating on 3/8" fasteners, preventing loosening from vibration and thermal expansion.
Specification Summary & Compliance
This flat washer features dimensional compliance with ASME B18.22.1 standards for inch system washers, ensuring precise fit and function. The manufacturing process adheres to strict quality controls for thickness consistency between 0.047-0.080". Environmental compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making these washers suitable for global supply chains and environmentally conscious manufacturing operations.
