Professional Applications & Engineering Value

This nylon plastic flat washer delivers critical engineering solutions where metal fasteners fail. The non-conductive properties make it ideal for electrical enclosures, control panels, and marine applications where electrical insulation prevents short circuits and galvanic corrosion. The green nylon construction withstands chemical exposure and moisture without degradation, while the wide temperature range (-40°F to 300°F) ensures reliability in outdoor, automotive, and HVAC systems. As an ASME B18.22.1 compliant washer, it provides consistent load distribution for No. 10 screws, preventing joint loosening and material damage in vibration-prone industrial equipment.
