Professional Applications & Engineering Value

This nylon plastic sleeve washer delivers critical engineering solutions where electrical insulation and corrosion resistance are paramount. The off-white nylon construction provides excellent dielectric properties while resisting moisture, chemicals, and UV degradation. Engineered for 1/4" screw applications in inch measurement systems, the precise 0.252" ID and 0.365" OD dimensions ensure secure fastening without loosening under vibration. The sleeve design offers superior load distribution compared to flat washers, making it ideal for industrial equipment, electrical enclosures, and outdoor applications where temperature fluctuations from -40°F to 180°F would compromise lesser materials. Its non-conductive properties prevent galvanic corrosion between dissimilar metals while providing reliable insulation in electrical assemblies.

Specification Summary & Compliance

This sleeve washer features precise inch system dimensions with 0.252" internal diameter and 0.365" outer diameter, specifically designed for 1/4" screw applications. The nylon plastic material achieves Rockwell R118 hardness for consistent mechanical performance. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance with the latest substance restrictions, ensuring environmental safety and regulatory adherence for global industrial applications.
