Professional Applications & Engineering Value

This 1/2"-13 UNC hex head screw is engineered to solve critical challenges in industrial assembly and construction. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for outdoor, marine, and chemical processing applications where environmental factors degrade lesser fasteners. The coarse thread design ensures quick and reliable installation in softer materials or where vibration resistance is needed, while the fully threaded shank offers consistent clamping force. With an 80,000 PSI tensile strength and external hex drive, it withstands high stress and allows for precise torque control, preventing joint failure in machinery, structural frames, and heavy-duty equipment. This combination of material properties and thread form delivers long-term reliability, reducing downtime and replacement costs.
