Professional Applications & Engineering Value
This Grade 5 carriage bolt delivers exceptional engineering value through its zinc-plated steel construction and precision UNC coarse threading. The combination of 120,000 PSI tensile strength and Rockwell C25 hardness provides optimal resistance to shear forces and vibration fatigue in heavy-duty applications. The square neck design eliminates the need for additional anti-rotation components, streamlining assembly in structural frameworks, machinery bases, and transportation equipment. The fully threaded configuration ensures maximum engagement depth while the rounded carriage head distributes clamping pressure evenly, preventing surface damage in wood-to-metal and structural steel connections commonly found in construction, agricultural equipment, and industrial manufacturing environments.
Specification Summary & Compliance
This carriage bolt maintains Class 3A thread fit tolerance for precise engagement and features 1/2"-13 UNC coarse thread specifications. Manufacturing complies with ASME B18.5 and SAE J429 Grade 5 standards, ensuring dimensional accuracy and mechanical properties. The product is certified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety regulations for industrial fastener applications.
