Professional Applications & Engineering Value
This 1/2"-13 UNC hex head screw is engineered to address common industrial challenges such as vibration loosening, material fatigue, and environmental degradation. The 316 Stainless Steel composition provides exceptional resistance to corrosion from chlorides and acidic conditions, making it suitable for marine, chemical processing, and offshore applications. The partial threading and defined grip length ensure that the unthreaded portion bears the shear load effectively, reducing stress concentration on the threads. Combined with a Rockwell B96 hardness and 75,000 psi tensile strength, this fastener delivers long-term reliability in heavy-duty assemblies, machinery, and structural frameworks where failure is not an option.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. It meets ASTM A193 specifications and is manufactured from ASTM Grade B8M 316 Stainless Steel, ensuring compliance with industry mechanical and material requirements. The product conforms to relevant standards for high-strength bolting applications, supporting quality assurance in demanding engineering environments.
