• Secure Fit for Standard Fasteners: Precisely designed with a 0.33" ID for 5/16" screws, ensuring easy installation and a stable, vibration-resistant connection.
• Durable Bonded Construction: The permanent metal-to-rubber bond prevents seal separation under stress, offering a consistent and dependable seal throughout the product lifecycle.
• Compliance with Industry Regulations: Meets RoHS 3 and REACH compliance standards, making it a safe and responsible choice for global industrial supply chains.
• Optimal Load Distribution: With an OD of 0.625", this washer effectively distributes pressure, protecting surfaces and preventing fastener loosening.

Professional Applications & Engineering Value

This metal bonded washer is engineered to solve critical sealing and corrosion challenges in demanding industrial applications. The combination of a hot-dipped galvanized steel body and a neoprene rubber seal creates a robust barrier against environmental factors, effectively preventing leaks and thread corrosion in equipment exposed to weather, chemicals, or temperature fluctuations. Its precise 0.33" ID ensures a perfect fit for 5/16" screws, simplifying inventory and installation in machinery, electrical enclosures, automotive assemblies, and construction frameworks. By integrating a Durometer 65A seal, it maintains flexibility at low temperatures while resisting compression set, delivering reliable performance that reduces maintenance needs and downtime in weatherproof sealing systems.
