Professional Applications & Engineering Value
Engineered for structural steel connections and heavy machinery assembly, these Grade A325 hex head screws deliver critical performance where failure is not an option. The hot-dipped galvanized steel construction provides superior protection against corrosion in outdoor and industrial environments, while the UNC coarse thread design ensures rapid installation and reliable clamping force. With partial threading optimizing both grip length and unthreaded shank strength, these fasteners prevent joint slippage in dynamic load applications. The external hex drive allows for high-torque installation, making them ideal for construction projects, bridge work, and industrial equipment requiring certified structural fasteners.
Specification Summary & Compliance
These 3/4"-10 hex head screws feature Class 2A thread fit per UNC standards with precise 5" length and 3 5/8" grip length. Manufactured to ASME B18.2.6, ASTM A325, and ASTM F3125 specifications, they guarantee dimensional accuracy and mechanical properties. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) ensures environmental responsibility and workplace safety standards are met for industrial applications worldwide.
