Professional Applications & Engineering Value
This nylon flat washer delivers critical engineering solutions where metal washers fail. The Nylon Plastic construction provides essential electrical insulation in electronic enclosures while preventing galvanic corrosion in marine and chemical processing equipment. With its 0.125" ID precision fit for No. 4 screw size applications, it ensures uniform clamping force in automotive assemblies, electrical panels, and outdoor equipment. The temperature range from -40°F to 300°F makes it ideal for HVAC systems and industrial machinery exposed to thermal cycling. The green color facilitates quality control in high-volume manufacturing, while the ASME B18.22.1 compliance guarantees dimensional consistency across replacement cycles.
Specification Summary & Compliance
This flat washer features inch system dimensions with 0.125" internal diameter, 0.375" outer diameter, and 0.036-0.045" thickness range for precise fitment. Manufactured to ASME B18.22.1 dimensional specifications ensuring mechanical compatibility. The washer demonstrates full compliance with RoHS 3 (2015/863/EU) restrictions and REACH (EC 1907/2006) regulations regarding substance control. Material hardness rated at Rockwell R115 provides consistent performance under mechanical stress.
