Professional Applications & Engineering Value

These 2024 aluminum hex head screws deliver critical engineering advantages where weight reduction and corrosion resistance are paramount. The UNC coarse thread configuration provides superior performance in soft materials and applications subject to vibration, preventing loosening while maintaining Class 2A thread fit precision for consistent assembly. The external hex drive design enables high torque application without stripping, making them ideal for structural assemblies, machinery frames, and transportation equipment where 30,000 psi tensile strength ensures joint integrity under dynamic loads. The fully threaded design maximizes grip length for enhanced load distribution, while the aluminum construction eliminates galvanic corrosion concerns when mating with similar materials.

Specification Summary & Compliance

Manufactured to precise UNC coarse thread standards with Class 2A thread fit tolerance ensuring consistent mating and reliable performance. The 1/2"-13 thread size with 4" length provides standardized dimensions for interchangeability across industrial applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming adherence to international substance restriction standards for industrial components.
