S-92186A152 1 1/8"-7 x 5" 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 industrial environments and chemical exposure
• Exceptional mechanical strength with 70,000 PSI tensile strength and Rockwell B70 hardness for reliable performance under heavy loads
• Optimized assembly efficiency through coarse UNC threading and Class 2A thread fit, ensuring faster installation and reduced galling risk
• Secure fastening in demanding applications with a 5" length and partial threading for controlled clamp load distribution
• Enhanced torque transmission via the external hex drive and large 1 11/16" head width, preventing tool slippage during installation
• Full regulatory compliance with ASME B18.2.1 standards and environmental directives (RoHS 3, REACH) for global project suitability
• Reduced maintenance and replacement costs due to durable material properties and corrosion-resistant design

Professional Applications & Engineering Value

This 1 1/8"-7 UNC hex head screw in 316 stainless steel addresses critical engineering challenges in heavy machinery, marine equipment, and chemical processing plants. Its coarse thread design resists vibration loosening and enables quick assembly in structural steel connections and large-diameter piping systems. The partially threaded shank concentrates clamping force precisely where needed, preventing joint failure in high-stress applications. With external hex drive compatibility, it ensures maximum torque application without stripping, while the corrosion-resistant properties eliminate premature degradation in humid or corrosive environments, significantly extending service life and reducing downtime.

Specification Summary & Compliance

This screw maintains Class 2A thread fit tolerances per UNC standards, with precise dimensions including 1.125" thread diameter and 2 1/2" minimum thread length. Manufacturing adheres to ASME B18.2.1 specifications for hex head bolts, ensuring dimensional consistency and mechanical performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and unrestricted use in international industrial markets.
