S-90313A267 0.531" ID x 1.625" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
• Optimized load distribution due to the 1.625" outer diameter and 0.080-0.115" thickness range, reducing stress on fastened components.
• Precise fit for 1/2" screws with a 0.531" inner diameter, minimizing play and enhancing assembly stability.
• Environmental compliance assurance with RoHS 3 and REACH adherence, meeting strict industrial safety standards.
• Durable flat washer design for repeated use in heavy-duty applications without deformation.
• Versatile inch-system compatibility, ideal for machinery and equipment requiring standardized imperial measurements.

Professional Applications & Engineering Value

This 18-8 stainless steel flat washer is engineered to address common industrial challenges, such as galvanic corrosion and uneven load-bearing surfaces. Its corrosion-resistant material prevents rust in humid or chemical-exposed settings, extending service life in applications like marine equipment, food processing machinery, and outdoor structures. The precise 1/2" inner diameter and 1.625" outer diameter ensure a snug fit on standard screws, while the controlled 0.080-0.115" thickness provides consistent pressure distribution, reducing the risk of joint loosening or material fatigue. Ideal for heavy-duty washers in mechanical assemblies, it supports reliable performance in industrial washers systems where vibration and high loads are prevalent.

Specification Summary & Compliance

This flat washer features an inner diameter of 0.531", outer diameter of 1.625", and thickness range of 0.080-0.115", designed for use with 1/2" screws in inch measurement systems. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial components.
