S-90097A260 0.504" ID x 0.645" OD Insulating Washers

Key Features & Benefits at a Glance

• Excellent vibration resistance and electrical insulation provided by durable nylon plastic construction, preventing short circuits and loosening in dynamic applications
• Reliable performance across extreme temperature environments with an operating range from -40°F to 180°F, maintaining integrity in both freezing and moderately heated conditions
• Precise fit for 1/2" screw assemblies with 0.504" ID and 0.548" sleeve OD, ensuring secure placement and uniform load distribution
• Enhanced durability and wear resistance from Rockwell R118 hardness, reducing deformation under pressure and extending service life
• Full compliance with global environmental standards including RoHS 3 and REACH, making it suitable for regulated industries and export markets
• Corrosion-free and lightweight solution ideal for applications where metal washers could cause galvanic corrosion or add unnecessary weight
• Optimized sleeve design (0.5" height) provides superior spacing and alignment in bolted joints, minimizing assembly errors

Professional Applications & Engineering Value

This nylon sleeve washer delivers critical engineering value in industrial settings where electrical insulation, chemical resistance, and weight reduction are paramount. The off-white nylon plastic material prevents galvanic corrosion between dissimilar metals, making it ideal for electrical enclosures, automotive assemblies, and outdoor equipment. Its sleeve-type design with 0.655" overall height acts as both a spacer and insulator, solving common issues of component misalignment and electrical leakage. With a temperature range from -40°F to 180°F, it maintains dimensional stability in harsh environments where thermal expansion would compromise metal washers. The Rockwell R118 hardness ensures consistent performance under vibration without cracking or deforming, providing long-term reliability in heavy machinery, conveyor systems, and structural fastening applications.
