Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this 1/2"-13 UNC hex head screw combines Grade A307 steel construction with zinc plating to address common challenges in construction, machinery assembly, and structural frameworks. The coarse thread design prevents cross-threading while providing superior pull-out resistance, making it ideal for wood-to-metal connections and structural steel applications. The partial threading ensures maximum clamping force where needed, while the external hex drive accommodates high-torque installation requirements. These industrial hex bolts deliver reliable performance where vibration resistance and long-term structural integrity are critical.
Specification Summary & Compliance
This inch system fastener features Class 2A thread fit per UNC standards with precise dimensional accuracy. Manufactured in compliance with ASME B18.2.1 specifications and ASTM A307 grade requirements. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industries.
