S-92303A101 0.219" ID x 1" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for humid or chemically aggressive environments
• Enhanced load distribution from the 1" outer diameter, preventing surface damage and fastener loosening under vibration
• Precision fit for No. 10 screws with 0.219" inner diameter, ensuring secure alignment and reduced installation errors
• Exceptional mechanical durability due to Rockwell B83 hardness, maintaining shape under high clamping pressures
• Long-term reliability in demanding applications with consistent 0.110-0.140" thickness for uniform performance
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries
• Broad industrial compatibility with inch measurement system, simplifying procurement for North American machinery and equipment

Professional Applications & Engineering Value

These 18-8 stainless steel flat washers deliver critical engineering value by addressing common failure points in industrial assemblies. The corrosion-resistant material eliminates rust-induced degradation in marine, chemical processing, and outdoor applications, while the precise inner diameter for No. 10 screws prevents misalignment that can lead to thread stripping or joint failure. With a Rockwell B83 hardness rating, they withstand repeated torque and vibration without deforming, making them ideal for heavy-duty machinery, automotive subsystems, and structural bolting. The optimized 1" outer diameter distributes clamping force effectively, protecting soft materials and reducing maintenance cycles in high-stress environments.

Specification Summary & Compliance

Manufactured to standard inch dimensions with 0.219" inner diameter and 1" outer diameter, these flat washers maintain consistent 0.110-0.140" thickness for reliable performance. The 18-8 stainless steel composition ensures mechanical integrity, while compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards confirms adherence to hazardous substance restrictions for industrial safety and environmental protection.
