• Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B70 hardness for high-stress applications
• Precise, reliable fastening ensured by Class 3A thread fit for minimal backlash and secure assemblies
• Optimized for high-torque installation with a standard 1/4" hex drive and socket head design
• Broad industrial compatibility from coarse UNC threads and right-hand direction for common machinery
• Full-length threading provides consistent grip and adjustment along the entire 7/8" length
• Compliant with global regulations including RoHS 3 and REACH for safe, sustainable use

Professional Applications & Engineering Value

This 316 Stainless Steel Socket Head Cap Screw is engineered to solve critical challenges in demanding industrial settings. Its corrosion-resistant material and passivated finish prevent degradation from chemicals, moisture, and salt, making it ideal for marine, chemical processing, and food-grade equipment. The Class 3A thread fit and UNC coarse threads deliver vibration resistance and quick assembly in high-volume production, while the hex drive socket head allows for high-torque tightening in confined spaces. With a 70,000 psi tensile strength, it maintains integrity under dynamic loads, reducing failure risks in machinery, automotive, and structural applications.

Specification Summary & Compliance

This fastener features a 5/16"-18 UNC coarse thread with Class 3A precision fit for tight tolerances, a 7/8" length, and full threading. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial components.
