Professional Applications & Engineering Value
Engineered for demanding industrial and construction applications, these Grade 5 hex head screws deliver exceptional performance where structural integrity is paramount. The partially threaded design concentrates the UNC coarse threads precisely where maximum grip is required, while the unthreaded shank provides superior shear strength. The zinc plated steel construction offers reliable corrosion resistance in environments where moisture and chemical exposure are concerns. With external hex drive compatibility and right-hand threading, installation becomes efficient using standard tools, reducing assembly time while maintaining the 120,000 psi tensile strength needed for critical connections in machinery, structural frameworks, and heavy equipment applications.
Specification Summary & Compliance
This 1/2"-13 x 12" hex head screw features Class 2A thread fit tolerance per UNC standards with partial threading extending a minimum of 1½ inches. Manufactured to ASME B18.2.1 specifications and SAE J429 Grade 5 requirements, ensuring dimensional accuracy and mechanical properties. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making these fasteners suitable for global industrial applications requiring verified material safety and performance standards.
