Professional Applications & Engineering Value
This 1/2"-13 UNC hex head screw delivers critical engineering solutions where corrosion and mechanical stress are primary concerns. Manufactured from 316 Stainless Steel and meeting ASTM A193 Grade B8M specifications, it addresses failure risks in chemical processing, offshore platforms, and marine equipment by resisting pitting and chloride-induced corrosion. The coarse thread design ensures rapid assembly and vibration resistance, while the external hex drive accommodates high-torque applications. With partial threading, it provides unthreaded shank strength where shear loads are present, making it indispensable for structural connections, pump systems, and valve assemblies in aggressive environments.
Specification Summary & Compliance
This fastener adheres to Class 2A thread fit tolerances per UNC standards, ensuring consistent interchangeability. It complies with ASTM A193 for high-temperature service and is manufactured from 316 Stainless Steel for enhanced corrosion resistance. The screw meets common industry requirements for mechanical properties, including 75,000 psi tensile strength and Rockwell B96 hardness, and is suitable for applications requiring RoHS and REACH compliance due to its material composition.
