- Optimal load distribution thanks to the large 1.75" outer diameter, preventing surface damage and joint loosening
- Precise fit for 7/8" screws with 0.906" inner diameter ensuring secure fastening and reduced vibration
- Enhanced durability from Rockwell B83 hardness rating, maintaining shape under heavy mechanical stress
- Regulatory compliance assurance with RoHS 3 and REACH standards for safe, environmentally responsible sourcing
- Consistent thickness control between 0.230-0.255" for reliable spacing and uniform clamping force
- Heavy-duty industrial suitability in inch measurement system for compatibility with standard North American equipment
Professional Applications & Engineering Value
This heavy-duty flat washer addresses critical engineering challenges in industrial assemblies where corrosion, vibration, and high loads compromise fastener integrity. Manufactured from 18-8 stainless steel, it provides exceptional resistance to rust and chemical exposure in marine, chemical processing, and outdoor applications. The precise 0.906" ID ensures perfect alignment with 7/8" screws, eliminating play that causes wear, while the generous 1.75" OD distributes clamping force over a wider area to prevent surface indentation on soft materials. With its Rockwell B83 hardness, this flat washer maintains dimensional stability under repeated stress cycles, making it ideal for heavy machinery, structural steel connections, and permanent installations where disassembly is impractical.
Specification Summary & Compliance
This precision flat washer features inch system dimensions with 0.906" inner diameter, 1.75" outer diameter, and controlled thickness range of 0.230-0.255". Manufactured to standard flat washer specifications for 7/8" screw applications, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability for industrial procurement.
