Professional Applications & Engineering Value
This Grade 5 hex head screw delivers critical engineering solutions for industrial assembly challenges. The zinc plated steel construction combats environmental degradation in manufacturing facilities, while the 3/4"-10 UNC coarse threads prevent loosening in high-vibration machinery. With 120,000 psi tensile strength, it securely fastens structural components in construction equipment, automotive frames, and heavy machinery. The external hex drive allows high-torque installation using standard tools, reducing assembly time in production lines. These fully threaded fasteners distribute clamping force evenly across joined materials, preventing joint failure in load-bearing applications where reliability is paramount.
Specification Summary & Compliance
Manufactured to Class 2A thread fit tolerances with 3/4"-10 UNC coarse threading according to ASME B18.2.1 and SAE J429 standards. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage in regulated industries. The Grade 5 classification guarantees consistent mechanical properties including specified tensile strength and hardness values.
