Professional Applications & Engineering Value
These nylon plastic flat washers deliver critical engineering solutions where metal fasteners fall short. The Nylon material provides inherent corrosion resistance, making them ideal for chemical processing, marine, and outdoor applications where moisture and corrosive agents degrade metal components. Their excellent electrical insulation properties make them essential in electrical enclosures, control panels, and electronic assemblies to prevent grounding issues. The wide temperature tolerance (-40°F to 300°F) ensures reliable performance in automotive under-hood applications, HVAC systems, and industrial machinery exposed to thermal cycling. The Rockwell R115 hardness offers sufficient load distribution for No. 4 screw applications while preventing galvanic corrosion when used with dissimilar metals, extending service life in critical industrial assemblies.
Specification Summary & Compliance
This flat washer features precise inch system dimensions with 0.125" inner diameter and 0.312" outer diameter, specifically engineered for No. 4 screw applications. The manufacturing conforms to standard flat washer specifications with consistent thickness ranging from 0.250" to 0.400". The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial components.
