Professional Applications & Engineering Value
This nylon sleeve washer delivers critical engineering solutions where metal fasteners fall short. The off-white nylon plastic construction provides inherent electrical insulation and chemical resistance, making it ideal for electrical enclosures, marine equipment, and food processing machinery where conductivity or contamination must be avoided. The sleeve-type design with 0.6" OD creates an extended bearing surface that distributes clamping force evenly, preventing surface damage and maintaining joint integrity. With its wide temperature range from -40°F to 180°F, this washer maintains its mechanical properties in both freezing outdoor applications and heated industrial environments, ensuring reliable performance where thermal cycling would compromise other materials.
Specification Summary & Compliance
This inch-system sleeve washer features precise dimensional specifications including 0.441" ID for 7/16" screws, 0.6" OD, and 0.26" overall height with sleeve dimensions of 0.486" OD and 0.125" height. Manufactured to exacting standards with Rockwell R118 hardness for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
