- Optimized torque transmission through the external hex drive and 9/16" head width, allowing for secure installation with standard tools
- Quick assembly and vibration resistance from the coarse UNC thread, maintaining grip under dynamic loads
- Precise thread engagement with Class 2A fit, ensuring consistent fastening and reducing the risk of cross-threading
- Versatile partial threading design for applications requiring unthreaded shank sections to bear against materials
- Regulatory compliance assurance meeting ASME B18.2.1, RoHS 3, and REACH standards for safe, industry-approved use
Professional Applications & Engineering Value
Engineered for demanding industrial settings, this 3/8"-16 UNC hex head screw in 316 Stainless Steel delivers critical performance where corrosion and stress are concerns. The coarse thread design ensures rapid installation and superior resistance to loosening under vibration, making it ideal for machinery, structural frameworks, and marine equipment. Its partially threaded configuration provides a smooth shank for precise clamping in assembled components, while the external hex drive allows high-torque application without slippage. With a robust 70,000 psi tensile strength, it supports heavy-duty fastening in construction, chemical processing, and offshore applications, ensuring long-term reliability and reduced maintenance.
Specification Summary & Compliance
This screw adheres to Class 2A thread fit for consistent dimensional accuracy under the ASME B18.2.1 standard. It features a 3/8"-16 UNC coarse thread in a right-hand direction, with a minimum thread length of 1" and overall length of 3 1/2". Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental safety and regulatory alignment for industrial procurement.
