Professional Applications & Engineering Value

This nylon flat washer delivers critical engineering solutions where electrical insulation and corrosion resistance are paramount. The white nylon plastic material provides excellent dielectric properties, making it ideal for electrical enclosures, control panels, and electronic assemblies where current isolation is essential. Its non-conductive nature prevents galvanic corrosion between dissimilar metals, extending equipment lifespan in industrial settings. The precise 0.515" inner diameter ensures secure fitment on 1/2" screws, while the 0.875" outer diameter distributes clamping force effectively to prevent surface damage. These plastic washers are particularly valuable in maintenance applications where chemical exposure or moisture would degrade metal alternatives, offering reliable performance in demanding environments without compromising structural integrity.

Specification Summary & Compliance

This flat washer features dimensional specifications of 0.515" inner diameter, 0.875" outer diameter, and thickness ranging from 0.084" to 0.104", specifically engineered for use with 1/2" screw applications.
