Professional Applications & Engineering Value
This Grade 5 carriage bolt is engineered to address common challenges in industrial fastening, such as vibration loosening and material fatigue. The zinc-plated steel material offers robust protection against rust, ideal for construction and outdoor equipment where exposure to moisture is a concern. Its knurled neck grips firmly into materials, eliminating spin-out during torque application and enhancing joint integrity. With UNC coarse threads and Class 2A fit, it ensures smooth engagement in wood, metal, or composite assemblies, reducing installation errors. Partially threaded design concentrates strength where needed, making it a reliable choice for heavy-duty frameworks, machinery, and structural connections that demand high tensile strength and long-term reliability.
Specification Summary & Compliance
This carriage bolt features precise Class 2A thread fit with UNC coarse threading (3/8"-16 size) and a minimum thread length of 1". It complies with SAE J429 specifications for dimensional accuracy and mechanical properties. Additionally, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safety and regulatory adherence for various industrial and commercial applications.
