Professional Applications & Engineering Value
These 3/8"-16 UNC hex head screws deliver exceptional engineering value in demanding industrial applications. The Black-Oxide coated 18-8 Stainless Steel construction provides superior corrosion resistance, making them ideal for outdoor equipment, marine environments, and chemical processing facilities where moisture and corrosive elements are concerns. The coarse thread design ensures quick assembly in structural steel connections, machinery frames, and heavy equipment where vibration resistance is critical. With 80,000 PSI tensile strength and Rockwell B70 hardness, these partially threaded fasteners maintain clamping force under extreme loads, preventing joint failure in construction, automotive, and manufacturing applications. The external hex drive allows for high-torque installation using standard tools, streamlining assembly processes while maintaining secure fastening integrity.
Specification Summary & Compliance
These hex head screws feature precise Class 2A thread fit with 3/8"-16 UNC coarse threading and 1½" length with 1" minimum thread length. Manufactured to ASME B18.2.1 specifications, they ensure dimensional accuracy and interchangeability. The fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for global industrial applications with strict chemical substance restrictions.
