Professional Applications & Engineering Value

This Nylon 6/6 plastic sleeve washer delivers critical engineering solutions where metal components fail. The off-white nylon construction provides essential electrical insulation in control panels, motor assemblies, and electronic enclosures, preventing short circuits and ground faults. Its corrosion-resistant properties make it ideal for chemical processing, marine, and outdoor applications where moisture and corrosive agents degrade metal washers. The sleeve design extends through the material thickness, creating superior bearing surface distribution and preventing embedment in softer materials. Engineered for 1/4" screw sizes in inch system applications, this washer maintains consistent performance across the -40°F to 180°F temperature range, ensuring reliability in both freezing and elevated temperature environments common in industrial settings.

Specification Summary & Compliance

This precision-engineered sleeve washer features exact dimensional specifications including 0.257" ID, 0.5" OD, and 0.125" thickness with Rockwell R108 hardness for consistent performance. Manufactured to inch system standards for proper fit with 1/4" screws, the component maintains dimensional stability across its operating range. The product is fully RoHS 3 (2015/863/EU) compliant and meets REACH (EC 1907/2006) requirements, ensuring adherence to international environmental and safety regulations for hazardous substance restrictions.
