Professional Applications & Engineering Value
This nylon plastic sleeve washer is engineered to solve common industrial challenges, such as galvanic corrosion and component degradation in moist or chemically aggressive settings. Its off-white nylon material provides inherent lubrication and resistance to abrasion, making it perfect for electrical enclosures, automotive assemblies, and machinery where metal fasteners are unsuitable. The sleeve type design increases the bearing surface, which helps distribute load more evenly and prevents embedment into softer materials. This design, combined with a temperature range of -40°F to 180°F, ensures long-term reliability in applications exposed to thermal cycling, from outdoor equipment to HVAC systems, reducing maintenance needs and downtime.
Specification Summary & Compliance
This washer features precise inch system dimensions with an Inside Diameter (ID) of 0.379" and Outside Diameter (OD) of 0.535", designed for a 3/8" screw size. It is manufactured from nylon plastic with a hardness of Rockwell R118 and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and suitable for use in regulated industries.
