Professional Applications & Engineering Value

These 3/8"-16 UNC hex head screws deliver exceptional engineering value through their hot-dipped galvanized steel construction, providing superior corrosion protection that extends service life in demanding environments like construction, machinery assembly, and outdoor infrastructure. The coarse thread design ensures rapid installation and superior resistance to vibration loosening, while the partial threading optimizes clamping force distribution. With 60,000 PSI tensile strength and Rockwell B69 hardness, these external hex drive fasteners maintain structural integrity under heavy loads, making them ideal for structural steel connections, equipment frames, and heavy machinery where reliability is critical. The combination of right-hand thread orientation and standardized dimensions ensures compatibility with existing industrial systems and tooling.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit tolerance for consistent performance across UNC coarse thread applications. These hex head screws comply with ASME B18.2.1 specifications and ASTM A307 material standards, ensuring mechanical properties meet industrial requirements. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming they contain no restricted substances. The 2" length with 1" minimum thread length provides optimal engagement for various material thicknesses while maintaining the specified mechanical performance.
