Professional Applications & Engineering Value
This nylon sleeve washer delivers critical engineering solutions where metal fasteners fall short. The off-white nylon plastic construction provides essential electrical insulation in panel manufacturing, control systems, and electronic enclosures while eliminating galvanic corrosion risks. With its 1.155" overall height and 0.548" sleeve OD, it creates optimal spacing and vibration dampening in machinery assembly. The material's inherent corrosion resistance makes it perfect for food processing, marine, and chemical handling equipment where moisture and cleaning chemicals degrade metal washers. Operating reliably from -40°F to 180°F, it maintains dimensional stability in outdoor, automotive, and HVAC applications where temperature fluctuations compromise ordinary washers.
Specification Summary & Compliance
This inch-system sleeve washer features precise dimensions: 0.504" ID, 0.645" OD, 1.155" overall height with 1" sleeve height and 0.548" sleeve OD, engineered for 1/2" screw size applications. Manufactured from nylon plastic with Rockwell R118 hardness rating, it maintains consistent performance across specified temperature ranges. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial procurement.
