Professional Applications & Engineering Value

This M16 nylon plastic sleeve washer delivers critical engineering solutions where metal fasteners would cause galvanic corrosion or electrical short circuits. The nylon construction provides inherent insulation properties, making it ideal for electrical enclosures, automotive assemblies, and machinery where non-conductive spacing is required. With its 20.3mm OD and 23.1mm overall height, it effectively distributes load pressure and prevents surface damage. The sleeve design (17.3mm OD, 19.05mm height) ensures precise alignment and protects threaded components from abrasion. Its ability to maintain integrity across extreme temperatures (-40°F to 180°F) makes it suitable for outdoor equipment and industrial applications subject to thermal cycling, while the Rockwell R118 hardness guarantees long service life despite constant vibration and mechanical stress.
