S-92186A978 1 1/4"-7 x 10" ASME B18.2.1 Super-Corrosion-Resistant 316 Stainless Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance thanks to 316 stainless steel construction, ideal for harsh industrial and marine environments
• High mechanical strength with 70,000 psi tensile strength and Rockwell B70 hardness for reliable performance under heavy loads
• Secure and efficient installation enabled by the external hex drive and 1 7/8" head width for high torque application
• Optimized thread engagement with coarse UNC threading and Class 2A fit, ensuring easy starting and vibration resistance
• Versatile partial threading on a 10" length provides a strong grip where needed while allowing for unthreaded shank strength
• Guaranteed dimensional consistency and interchangeability through compliance with the ASME B18.2.1 standard
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives

Professional Applications & Engineering Value

This 1 1/4"-7 UNC hex head screw in 316 stainless steel is engineered to solve critical challenges in demanding applications. Its superior corrosion resistance makes it a prime choice for chemical processing, marine, and offshore installations, where exposure to chlorides and other corrosive agents is a constant threat. The coarse thread (UNC) and Class 2A thread fit provide excellent vibration resistance and faster assembly in structural steel, heavy machinery, and large-scale construction projects. The combination of a 10" length and partial threading offers the ideal balance, allowing the unthreaded shank to bear shear loads while the threaded portion ensures secure clamping. Manufactured to ASME B18.2.1, this external hex drive fastener delivers the reliability and repeatability required for professional engineering and maintenance operations.

Specification Summary & Compliance

This fastener features a 1 1/4"-7 UNC thread with a Class 2A thread fit for consistent dimensional accuracy. It is manufactured in accordance with the ASME B18.2.1 specification and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent industry standards for performance and environmental safety.
