Professional Applications & Engineering Value
These nylon plastic flat washers deliver critical engineering solutions where metal alternatives fail. The nylon material provides inherent corrosion resistance, making them ideal for chemical processing, marine, and outdoor applications where moisture and corrosive elements are present. Their electrical insulation properties prevent short circuits in electrical enclosures, control panels, and electronic assemblies. The precise 0.188" inner diameter ensures perfect alignment with No. 8 screws, while the 0.5" outer diameter distributes clamping force effectively to prevent surface damage on soft materials. With a temperature range from -40°F to 180°F, these washers maintain dimensional stability in both industrial freezing conditions and elevated temperature environments, solving common thermal expansion issues that compromise fastener integrity.
Specification Summary & Compliance
This flat washer features inch system dimensions with 0.188" inner diameter, 0.5" outer diameter, and thickness ranging from 0.035" to 0.045". Manufactured from nylon plastic with Rockwell R115 hardness rating, it's specifically designed for No. 8 screw applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for global industrial use.
