Professional Applications & Engineering Value
This Nylon Plastic Sleeve Washer delivers critical engineering solutions where metal alternatives would cause galvanic corrosion or electrical insulation issues. The 0.379" ID provides precise alignment for 3/8" screws in machinery assemblies, while the 0.535" OD distributes clamping force effectively across sensitive surfaces. Manufactured from temperature-resistant Nylon, it maintains dimensional stability from -40°F to 180°F, making it ideal for outdoor equipment, electrical enclosures, and automotive components where thermal cycling occurs. The sleeve design adds extra bearing surface, preventing pull-through in soft materials and extending fastener system lifespan in industrial washers applications.
