S-91525A114 0.203" ID x 1" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance from 316 stainless steel construction, ideal for harsh chemical and marine environments
• Precise dimensional fit with 0.203" inner diameter specifically engineered for No. 10 screw applications
• Optimal load distribution through 1" outer diameter design, preventing surface damage and joint loosening
• Consistent performance with 0.033-0.047" thickness range ensuring reliable spacing and vibration resistance
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications
• Long-term durability maintaining structural integrity in high-moisture and temperature-variable conditions
• Interchangeable compatibility with inch-system fasteners across various industrial equipment and assemblies

Professional Applications & Engineering Value

These 316 stainless steel flat washers deliver critical engineering value in applications where corrosion resistance and chemical stability are paramount. The inch-system dimensions (1" OD × 0.203" ID) provide precise compatibility with No. 10 screw sizes commonly used in industrial machinery, marine hardware, and chemical processing equipment. The flat washer design effectively distributes clamping force across wider surfaces, preventing bolt head embedment and maintaining joint integrity under vibration and thermal cycling. This makes them particularly valuable in demanding environments where standard carbon steel washers would rapidly deteriorate, ensuring long-term reliability in wastewater treatment, offshore platforms, and food processing facilities where stainless steel construction is essential for both performance and regulatory compliance.

Specification Summary & Compliance

Manufactured to standard inch-system dimensions with 1" outer diameter, 0.203" inner diameter, and 0.033-0.047" thickness range. These flat washers are engineered for use with No. 10 screw sizes and manufactured from 316 stainless steel for optimal performance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures suitability for industrial applications with strict environmental and safety requirements.
