Professional Applications & Engineering Value

This Nylon 6/6 plastic sleeve washer delivers critical engineering solutions where metal fasteners fall short. The sleeve-type design provides superior insulation properties, making it ideal for electrical enclosures, control panels, and electronic assemblies where preventing electrical conductivity is paramount. The off-white nylon construction offers exceptional resistance to chemicals, oils, and moisture, eliminating corrosion concerns in manufacturing facilities, marine applications, and outdoor equipment. With its 0.26" ID precision-machined for 1/4" screws, this washer ensures perfect alignment and consistent compression, while the 0.438" overall height and 0.375" sleeve height provide optimal spacing and protection for sensitive components. The material's natural lubricity reduces friction during installation, preventing galling and ensuring smooth assembly operations in automated production environments.
