Professional Applications & Engineering Value
This nylon plastic self-retaining washer delivers critical engineering solutions where vibration resistance and electrical insulation are paramount. The self-retaining feature addresses common assembly challenges by eliminating washer migration during high-speed production, while the nylon material provides natural lubrication that prevents galling on mating surfaces. Ideal for electrical enclosures, automotive components, and outdoor equipment, this washer maintains performance across extreme temperature fluctuations from -40°F to 180°F. The precision inch dimensions (1.07" ID, 1.385" OD) ensure reliable seating on 1" screws, reducing rework and improving assembly quality in industrial fastening applications.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 1.07" inner diameter, 1.385" outer diameter, and thickness ranging 0.052-0.072". The washer features Rockwell R120 hardness rating and complies with RoHS 3 (2015/863/EU) environmental directives. Designed specifically for 1" screw applications within the inch measurement system, this component maintains structural integrity across the specified temperature range of -40°F to 180°F without compromising performance.
