S-92186A870 3/4"-10 x 8 1/2" ASME B18.2.1 Super-Corrosion-Resistant 316 Stainless Steel Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments including marine and chemical applications
• Exceptional mechanical strength offering 70,000 psi tensile strength and Rockwell B70 hardness for reliable performance under heavy loads
• Optimized thread engagement with UNC coarse threads and Class 2A fit ensuring quick assembly and vibration resistance
• Enhanced installation efficiency through external hex drive design providing secure tool grip and high torque application capability
• Strategic partial threading allowing unthreaded shank section to bear shear loads while threaded portion secures components
• Regulatory compliance assurance meeting ASME B18.2.1 specifications and environmental standards including RoHS 3 and REACH
• Dimensional precision with 8½" length and controlled thread length providing consistent performance in structural applications

Professional Applications & Engineering Value

This 3/4"-10 UNC hex head screw delivers critical engineering solutions where corrosion resistance and structural integrity are paramount. The 316 stainless steel composition provides exceptional protection against chloride-induced stress corrosion cracking, making it ideal for marine equipment, chemical processing plants, and coastal infrastructure. The partially threaded design creates a strategic balance where the unthreaded shank bears shear loads while the coarse UNC threads maintain secure fastening in vibration-prone applications. With external hex drive compatibility, installers achieve high torque values without stripping, ensuring reliable connections in heavy machinery, structural steel frameworks, and industrial equipment assemblies where 70,000 psi tensile strength prevents joint failure under extreme conditions.

Specification Summary & Compliance

This industrial fastener maintains precise Class 2A thread fit per UNC standards with controlled dimensional accuracy. Manufacturing follows ASME B18.2.1 specifications governing hex head dimensions and mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) restriction of hazardous substances and REACH (EC 1907/2006) chemical safety standards. The inch system measurement ensures compatibility with North American industrial equipment and replacement part requirements.
