Professional Applications & Engineering Value
These 2024 aluminum hex head screws deliver optimal performance in applications where weight reduction, corrosion resistance, and structural integrity are critical. The UNC coarse threading with Class 2A fit ensures reliable engagement in aluminum and other soft materials, preventing cross-threading while maintaining vibration resistance. The external hex drive configuration allows for high torque application without stripping, making them ideal for assembly line production and maintenance operations. With full threading along the entire 2½" length, these screws provide maximum grip range for variable material thicknesses in aerospace components, electronic enclosures, and transportation equipment where aluminum fasteners must withstand cyclic loading without compromising joint security.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit tolerance for consistent performance. Features UNC coarse thread (5/16"-18) with right-hand direction and external hex drive (1/2" width, 13/64" height). Mechanical properties include Rockwell B40 hardness and 30,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets.
