S-95395A210 0.203" ID x 0.5" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance from high-quality brass material, ideal for harsh industrial environments and extending component lifespan.
• Precise fit for No. 10 screws with a 0.203" inner diameter, ensuring secure fastening and preventing loosening under vibration.
• Optimal load distribution provided by the 0.5" outer diameter, protecting surfaces and reducing stress on assembled materials.
• Enhanced durability and deformation resistance due to the Rockwell B60 hardness, maintaining washer integrity under heavy-duty use.
• Full regulatory compliance with RoHS 3 (including exemption 6(c) for lead in copper alloy) and REACH, ensuring safe and unrestricted use in global markets.
• Reliable dimensional stability with a controlled thickness range of 0.079-0.099", guaranteeing consistent performance in precision assemblies.
• Excellent electrical and thermal conductivity inherent to brass, making it suitable for specialized electrical and plumbing applications.

Professional Applications & Engineering Value

Engineered for demanding industrial applications, this brass flat washer addresses critical challenges like galvanic corrosion and component failure. Its copper alloy composition inherently resists rust and degradation, making it a superior choice for electrical connections, marine hardware, and plumbing systems where moisture is a concern. The precise 0.203" ID and 0.5" OD ensure a perfect match for No. 10 screws, providing a stable bearing surface that prevents fastener embedment and distributes clamp load effectively. This solves common assembly issues such as surface damage, joint instability, and premature wear, thereby enhancing the long-term reliability and safety of your mechanical fastenings.
