Professional Applications & Engineering Value
Engineered for demanding industrial applications, this 3/8"-16 UNC hex head screw in 316 Stainless Steel addresses critical challenges like corrosion, high stress, and assembly efficiency. The coarse thread and partial threading enhance load distribution and reduce the risk of cross-threading in machinery, structural frames, and equipment subjected to dynamic forces. Its external hex drive allows for high-torque installation, ensuring tight, secure connections in heavy-duty settings such as construction, marine hardware, and chemical processing plants. By combining 70,000 psi tensile strength with Rockwell B70 hardness, it delivers long-term reliability, minimizing maintenance and downtime in corrosive or high-vibration environments.
Specification Summary & Compliance
This screw adheres to Class 2A thread fit and UNC coarse thread standards with precise dimensions: 3/8"-16 thread size, 3 1/4" length, and 15/64" head height. It meets ASME B18.2.1 manufacturing specifications and is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring environmental safety and industry-wide acceptance for professional use.
