Professional Applications & Engineering Value
This M3 Nylon Plastic Sleeve Washer is engineered to address critical challenges in electrical insulation and corrosion prevention for industrial assemblies. Its off-white nylon construction provides a reliable dielectric barrier, preventing short circuits in electrical and electronic enclosures. The sleeve design offers extended protection along the bolt shaft, while the material's inherent resistance to chemicals and moisture eliminates galvanic corrosion risks when used with dissimilar metals. With a temperature range of -40°F to 180°F, it maintains dimensional stability in both freezing environments and elevated temperature applications, making it particularly valuable in automotive electronics, control panels, and outdoor equipment where environmental factors compromise metal washer performance.
Specification Summary & Compliance
This metric sleeve washer features precise dimensions with 3.1mm ID, 5mm OD, and 8mm overall height, specifically designed for M3 screw sizes. The manufacturing utilizes nylon plastic with Rockwell R118 hardness to ensure consistent performance. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components.
