• Optimized vibration resistance through the metal-to-rubber bonded design that prevents loosening under dynamic loads
• Precision dimensional compatibility with No. 8 screws (0.18" ID x 0.375" OD) for perfect fit and uniform sealing pressure
• Consistent sealing performance with Durometer 65A neoprene providing ideal compression and recovery characteristics
• Full regulatory compliance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These metal bonded washers deliver critical sealing solutions where standard washers fail. The 18-8 stainless steel base provides structural integrity while the permanently bonded neoprene rubber seal (Durometer 65A) creates an impermeable barrier against environmental contaminants. Engineered for No. 8 screw applications requiring reliable vibration dampening and thermal stability, these washers solve common industrial challenges in electrical enclosures, automotive assemblies, and outdoor equipment. The black neoprene seal maintains flexibility across extreme temperature cycles from -40°F to 250°F, preventing seal brittleness in cold conditions and maintaining compression at elevated temperatures. This combination of metal strength and rubber resilience ensures long-term performance in applications where both mechanical fastening and environmental protection are equally critical.
