S-94705A600 1"-8 x 2 1/2" ASTM A193 Steel Heavy Hex Head Screws for High-Pressure Applications

Key Features & Benefits at a Glance

• Exceptional tensile strength of 125,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Superior material durability with ASTM A193 Grade B7 steel and Rockwell C35 hardness provides excellent resistance to wear and deformation under load.
• Coarse UNC thread design offers faster installation and better performance in materials prone to stripping or where vibration is a concern.
• Class 2A thread fit guarantees consistent, precise engagement with nuts and tapped holes, facilitating smoother assembly and disassembly.
• Fully threaded shank maximizes grip length and load distribution, ideal for applications requiring uniform clamping force along the entire fastener.
• External hex drive allows for high-torque application with standard tools, speeding up installation in tight or hard-to-reach spaces.
• Corrosion-resistant steel construction enhances longevity in harsh industrial environments, minimizing maintenance and replacement costs.

Professional Applications & Engineering Value

This 1"-8 UNC Grade B7 steel hex head screw is engineered to address critical challenges in heavy-duty industrial settings, such as construction, machinery assembly, and structural applications. The coarse thread pitch and fully threaded design ensure rapid installation and superior holding power in brittle or soft materials, reducing assembly time and improving joint integrity. Made from ASTM A193 Grade B7 steel, it withstands extreme temperatures and high-pressure conditions, making it ideal for pressure vessels, valves, and flanges. The external hex drive provides a secure grip for high-torque tools, enabling efficient fastening even in confined spaces. By combining high tensile strength and Rockwell C35 hardness, this fastener minimizes the risk of stripping, shearing, or loosening under dynamic loads, ensuring long-term reliability and safety in demanding engineering projects.
