Professional Applications & Engineering Value
These 2024 aluminum hex head screws deliver optimal performance in weight-sensitive applications where corrosion resistance and strength are critical. The 3/8"-16 UNC coarse thread configuration ensures rapid installation in production environments while maintaining vibration resistance in machinery, aerospace components, and transportation equipment. The fully threaded design maximizes clamping force distribution, making them ideal for structural assemblies requiring uniform load bearing. With Rockwell B40 hardness and 30,000 psi tensile strength, these fasteners withstand mechanical stresses while the external hex drive accommodates high-torque applications without stripping. The aluminum construction prevents galvanic corrosion when paired with compatible materials, extending service life in demanding industrial settings.
Specification Summary & Compliance
This 4" hex head screw features precise Class 2A thread fit per UNC standards with 3/8"-16 coarse threading and right-hand direction. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial applications worldwide. The fastener maintains dimensional accuracy with 9/16" head width and 15/64" head height for consistent tool engagement across production runs.
