Professional Applications & Engineering Value

This Black-Oxide Alloy Steel Socket Head Cap Screw is engineered to address critical challenges in industrial settings, such as vibration loosening and corrosion-induced failures. The 10-24 UNC coarse thread and Class 3A fit deliver precise engagement, reducing the need for re-tightening in machinery, automotive, and heavy equipment assemblies. The partially threaded rod type allows for controlled clamping force, ideal for applications where unthreaded shank sections prevent thread damage. With a tensile strength of 170,000 psi and Rockwell C37 hardness, it withstands extreme mechanical stresses, while the black-oxide finish resists environmental degradation. These screws are perfect for high-strength fastening in construction, aerospace, and manufacturing, ensuring durability and compliance with stringent industry regulations.
