Professional Applications & Engineering Value
This M8 nylon sleeve washer solves critical engineering challenges where electrical insulation, chemical resistance, and weight reduction are paramount. The nylon plastic construction provides inherent dielectric properties, making it ideal for electrical enclosures, control panels, and electronic assemblies where metal components could cause short circuits. The sleeve design offers extended protection along the bolt shaft, preventing galvanic corrosion between dissimilar metals and maintaining consistent clamping force. With its broad temperature range from -40°F to 180°F, this washer performs reliably in both freezing outdoor environments and heated industrial settings, maintaining its dimensional stability and mechanical properties where thermal expansion would compromise metal washers.
Specification Summary & Compliance
This metric sleeve washer features precise dimensions: 8.1mm ID, 12mm OD, and 9mm overall height with 6.3mm sleeve height, engineered for M8 screw applications. Manufactured from off-white nylon plastic with Rockwell R118 hardness rating, it maintains consistent performance within specified tolerances. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international environmental and safety standards for industrial components.
