S-90107A034 0.625" ID x 1.375" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction, ideal for marine, chemical, and outdoor applications.
• Precise dimensional fit with a 0.625" inner diameter ensures a secure and stable interface for 9/16" screws, preventing loosening and misalignment.
• Optimal load distribution is achieved with a generous 1.375" outer diameter, protecting surfaces and reducing stress on assembled components.
• Consistent performance and reliability guaranteed by a controlled thickness range of 0.071-0.085", providing uniform pressure and spacing.
• Environmental and regulatory compliance with RoHS 3 and REACH standards, ensuring safety and suitability for global markets and sensitive industries.
• Long-term durability and low maintenance due to the inherent strength and non-magnetic properties of 316 stainless steel, reducing replacement frequency and lifecycle costs.
• Versatile industrial application across various sectors, supported by the inch system of measurement for broad compatibility with standard fastening systems.

Professional Applications & Engineering Value

Engineered for demanding conditions, these 316 stainless steel flat washers provide a critical solution for corrosion resistance where exposure to chlorides, acids, or extreme weather is a concern. The precise inner diameter of 0.625" ensures a perfect match for 9/16" screw size applications, eliminating play and enhancing joint integrity in structural assemblies, machinery, and marine equipment. The large 1.375" outer diameter effectively distributes clamping force, preventing surface damage and bolt head embedment. This combination of material excellence and dimensional accuracy addresses common industrial pain points like fastener failure, galvanic corrosion, and assembly inconsistency, making them a reliable choice for industrial washers in construction, chemical processing, and offshore projects.
