• Wide temperature tolerance from -40°F to 180°F, maintaining structural integrity in both freezing and elevated temperature applications
• Rockwell R108 hardness provides durable bearing surface and consistent performance under mechanical stress and vibration
• Precise No. 10 screw compatibility with 0.197" ID ensures secure fastening and proper load distribution in assembly applications
• Full regulatory compliance with RoHS 3 and REACH standards, meeting international environmental and safety requirements for industrial components
• Optimal sleeve design with 0.24" OD and 0.187" height provides enhanced stability and protection for fastener assemblies

Professional Applications & Engineering Value

This Nylon 6/6 plastic sleeve washer delivers critical engineering solutions where metal components would fail. The sleeve-type design with 0.24" sleeve OD and 0.187" sleeve height creates an effective barrier against moisture, chemicals, and electrical conductivity, making it ideal for electrical enclosures, control panels, and outdoor equipment. The off-white nylon construction maintains dimensional stability across the broad -40°F to 180°F temperature range, preventing the cracking or deformation common in inferior plastics. For No. 10 screw applications in automotive, electronics, and industrial machinery, this washer provides reliable insulation while distributing load evenly to prevent surface damage and maintain fastener integrity.

Specification Summary & Compliance
