• Rockwell B70 hardness provides excellent durability and resistance to wear, extending the service life of the fastener.
• Coarse UNC thread and Class 2A fit allow for faster assembly and easier alignment, improving installation efficiency.
• Partially threaded design offers enhanced grip and clamping force where needed, preventing loosening under vibration.
• External hex drive and hex head enable straightforward installation and removal with standard tools, minimizing labor time.
• Compliance with ASME B18.2.1, RoHS 3, and REACH guarantees consistent quality, safety, and environmental responsibility for industrial use.

Professional Applications & Engineering Value

This 3/8"-16 UNC Hex Head Screw is engineered to solve critical fastening challenges in industrial settings. The Black-Oxide 18-8 Stainless Steel material combats corrosion effectively, making it suitable for outdoor machinery, marine equipment, and chemical processing plants where moisture and chemicals are prevalent. Its partially threaded configuration ensures that the unthreaded shank bears shear loads efficiently, while the threaded portion provides secure tension in assemblies subject to vibration, such as heavy-duty frames, conveyor systems, and structural supports. With a coarse thread and external hex drive, it simplifies maintenance and reduces the risk of cross-threading during high-volume production. This screw delivers long-term reliability, minimizing downtime and replacement costs in industrial hex head fasteners applications.
