S-92916A320 0.12" ID x 0.281" OD General Purpose Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance from high-quality brass material, ensuring long-lasting performance in humid or demanding environments.
• Enhanced load distribution with precise 0.12" ID and 0.281" OD dimensions, preventing surface damage and loosening under vibration.
• Excellent durability due to Rockwell B60 hardness, maintaining structural integrity under repeated assembly and disassembly.
• Reliable fit for No. 4 screws, reducing installation errors and improving assembly efficiency in industrial applications.
• Strict compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries.
• Consistent thickness control (0.018-0.032") for uniform pressure distribution and secure fastening in inch-system assemblies.
• Wide industrial compatibility as a flat washer, suitable for electrical, plumbing, and machinery where non-sparking properties are valued.

Professional Applications & Engineering Value

This brass flat washer is engineered to address common industrial challenges such as galvanic corrosion, frequent maintenance cycles, and regulatory compliance demands. Its brass construction inherently resists rust and oxidation, making it ideal for electrical connections, marine hardware, and plumbing systems where moisture exposure is prevalent. The precise 0.12" ID and 0.281" OD ensure a snug fit on No. 4 screws, minimizing play and distributing clamp load evenly to protect sensitive surfaces from indentation. With Rockwell B60 hardness, it withstands mechanical stress without deforming, reducing the need for replacements in high-vibration environments like automotive assemblies or machinery frames. The RoHS 3 and REACH compliance further supports its use in electronics and consumer goods, meeting global environmental standards while delivering reliable corrosion-resistant performance.
