Professional Applications & Engineering Value
This 3/4"-10 Grade A325 hex head screw is engineered to address critical challenges in structural and heavy-duty applications. The hot-dipped galvanized steel construction delivers outstanding corrosion resistance, making it suitable for bridges, construction frameworks, and industrial machinery exposed to moisture and chemicals. The partially threaded design with a 1 3/8" thread length and coarse UNC spacing ensures secure grip and reduces the risk of loosening under dynamic loads. With an external hex drive and right-hand thread, it facilitates quick installation and high torque application, while the 120,000 psi tensile strength and Rockwell C19 hardness provide reliable performance in high-stress environments, minimizing maintenance and replacement costs.
Specification Summary & Compliance
This fastener features precise Class 2A thread fit and adheres to UNC coarse thread standards with a 3/4"-10 thread size. It complies with ASME B18.2.6, ASTM A325, and ASTM F3125 manufacturing specifications, ensuring dimensional accuracy and mechanical consistency. Additionally, it is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting international environmental and safety regulations for industrial use.
