• High tensile strength of 70,000 psi ensures reliable performance under heavy loads and vibration
• Precise Class 3A thread fit provides excellent engagement and reduces the risk of cross-threading
• 1/4" hex drive design allows for high torque application and secure installation in confined spaces
• Rockwell B70 hardness rating delivers exceptional durability and resistance to wear
• Partially threaded shank enables optimal clamping force distribution for critical assemblies
• Compliance with major regulations including RoHS 3 and REACH ensures environmental and safety standards are met

Professional Applications & Engineering Value

This 18-8 stainless steel socket head cap screw with 5/16"-18 UNC coarse threads is engineered to address common industrial challenges such as vibration loosening and corrosion-induced failure. The hex drive and standard socket head profile provide reliable torque transmission in high-stress applications including machinery, automotive assemblies, and structural frameworks. Its partially threaded design concentrates clamping force where needed most, while the Class 3A thread fit maintains precision in repetitive disassembly and reassembly cycles. The combination of 70,000 psi tensile strength and Rockwell B70 hardness makes it suitable for heavy-duty applications requiring long-term reliability and minimal maintenance.

Specification Summary & Compliance

This fastener features 5/16"-18 UNC coarse threads with Class 3A thread fit for precise dimensional accuracy. It meets ASME B18.3 manufacturing specifications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial standardization.
