Professional Applications & Engineering Value
This heavy-duty carriage bolt is engineered to solve critical fastening challenges in industrial and construction settings. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for outdoor structures, marine equipment, and chemical processing facilities. The square neck design effectively locks the bolt in place, eliminating rotation during torque application and ensuring stable connections in wood, metal, and composite materials. With UNC coarse threads and a fully threaded shank, it facilitates quick assembly and maintains strong holding power in high-vibration environments. Its rounded head minimizes protrusion and distributes pressure evenly, protecting surfaces in conveyor systems, machinery frames, and structural supports.
Specification Summary & Compliance
This carriage bolt features a 1/2"-13 UNC coarse thread with Class 2A fit for standard tolerance and easy installation. It meets ASME B18.5 dimensional and mechanical specifications, ensuring interchangeability and reliability. The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for industrial use.
