Professional Applications & Engineering Value
Engineered for demanding industrial applications, this 3/8"-16 UNC hex head screw addresses critical challenges in chemical processing, marine equipment, and high-temperature environments. The 316 Stainless Steel composition provides exceptional resistance to pitting and chloride stress corrosion cracking, while the ASTM A193 Grade B8M specification ensures consistent mechanical properties under sustained loads. The external hex drive facilitates high-torque installation in confined spaces, and the partially threaded design concentrates clamping force precisely where needed. With 75,000 psi tensile strength and Rockwell B96 hardness, this fastener maintains structural integrity in vibration-prone assemblies, making it ideal for pressure vessels, pump systems, and structural connections requiring heavy-duty fastening solutions.
Specification Summary & Compliance
This inch system fastener features 3/8"-16 UNC coarse threads with Class 2A thread fit tolerances for reliable mating compatibility. Manufacturing complies with ASTM A193 specification for high-temperature service, while material composition meets industry standards for 316 Stainless Steel fasteners. The right-hand thread direction and external hex drive configuration follow conventional industrial practices for consistent installation performance.
