S-92186A707 7/16"-20 x 2 1/2" ASME B18.2.1 Super-Corrosion-Resistant 316 Stainless Steel Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction, ideal for marine, chemical, and outdoor applications.
• High tensile strength of 70,000 psi ensures reliable performance under heavy loads and vibration, reducing the risk of fastener failure.
• Fine UNF thread (7/16"-20) provides a tighter, more secure fit compared to coarse threads, minimizing loosening in precision assemblies.
• External hex drive and hex head design allows for easy installation and high torque application with standard tools, speeding up assembly processes.
• Class 2A thread fit offers consistent, free-spinning assembly with commercial nuts, ensuring smooth and efficient production line operations.
• Partial threading allows for unthreaded shank sections to bear shear loads effectively, enhancing joint stability in structural applications.
• Compliance with ASME B18.2.1, RoHS 3, and REACH guarantees adherence to industry standards and environmental regulations, providing peace of mind for global sourcing.

Professional Applications & Engineering Value

This 316 stainless steel hex head screw is engineered to address critical challenges in demanding industrial settings, such as exposure to corrosive agents, high stress, and stringent regulatory requirements. The UNF fine thread configuration ensures superior clamping force and resistance to vibrational loosening, making it ideal for precision equipment, machinery, and structural frameworks where reliability is paramount. Its partially threaded design concentrates the thread engagement on specific sections, optimizing load distribution and preventing thread damage during repeated disassembly. With a Rockwell B70 hardness and robust external hex drive, it withstands high-torque installation without stripping, reducing maintenance downtime in applications like marine hardware, chemical processing plants, and heavy-duty construction. The inherent corrosion resistance of 316 stainless steel extends service life in humid or saline environments, delivering long-term cost savings and operational safety for B2B buyers.
