Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this Grade 5 hex head screw delivers critical performance where structural integrity matters most. The zinc plated steel construction provides essential corrosion protection in manufacturing facilities, construction sites, and machinery assembly. The 3/4"-10 UNC coarse thread configuration ensures rapid installation and superior resistance to vibration loosening, while the external hex drive design accommodates high-torque applications without stripping. With full threading along the entire 6" length, this fastener maintains consistent clamping force across thick materials and structural components, making it ideal for critical joints in equipment frames, structural steel connections, and heavy machinery assemblies where failure is not an option.
Specification Summary & Compliance
This hex head screw features precision Class 2A thread fit with UNC coarse threading (3/4"-10) and right-hand thread direction. Manufactured to ASME B18.2.1 specifications meeting SAE J429 Grade 5 requirements, with material certification for 120,000 psi tensile strength and Rockwell C25 hardness. The product is fully RoHS 3 (2015/863/EU) compliant and manufactured in the inch system with dimensional accuracy per applicable industrial standards.
