Professional Applications & Engineering Value

This nylon plastic sleeve washer is engineered to address common industrial challenges such as component abrasion, electrical conductivity risks, and environmental degradation. Its off-white nylon construction provides excellent dielectric strength, making it a top choice for electrical enclosures, automotive assemblies, and outdoor machinery where insulation is critical. The sleeve design enhances load-bearing capacity and prevents loosening under vibration, a frequent issue in dynamic systems. With a temperature range of -40°F to 180°F, it performs reliably in both freezing conditions and moderate heat, reducing the need for frequent replacements. The inch system measurements, including the precise 0.629" ID, ensure compatibility with standard 5/8" fasteners, streamlining installation in industrial maintenance and OEM production lines.

Specification Summary & Compliance

This washer adheres to standard inch system dimensions with an ID of 0.629", OD of 0.8", and overall height of 0.91". The sleeve features a 0.679" OD and 0.75" height, manufactured from nylon plastic with a hardness of Rockwell R118 for consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial use.
