Professional Applications & Engineering Value
This Nylon Plastic Flat Washer is engineered to solve critical challenges in industrial and electrical applications. Its non-conductive properties make it ideal for preventing galvanic corrosion and electrical isolation in assemblies, while the inherent corrosion resistance of nylon eliminates the need for additional protective coatings. The material's resilience across a broad temperature range from -40°F to 300°F ensures stability in environments with thermal cycling, preventing brittleness or melting. Designed for No. 10 screws with precise inner and outer diameters, it provides a secure fit that distributes load evenly, reducing stress concentration and extending the life of fastened components. This makes it a reliable choice for electrical enclosures, automotive assemblies, and machinery where durability and safety are paramount.
Specification Summary & Compliance
This flat washer features an ID of 0.203", OD of 0.734", and thickness range of 0.056-0.071", manufactured to ASME B18.22.1 specifications for dimensional accuracy and performance. It is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring adherence to environmental and safety standards for hazardous substances.
