Professional Applications & Engineering Value
This 1/2"-13 UNC Carriage Bolt in 18-8 Stainless Steel is engineered to address common industrial challenges such as vibration loosening and corrosion-induced failure. The square neck design ensures a firm grip in pre-drilled holes, making it ideal for structural frameworks, machinery assembly, and transportation equipment where rotational stability is critical. Its partially threaded configuration allows the unthreaded portion to act as a precise dowel, minimizing shear stress and maintaining alignment in heavy-duty fastening applications. With a Rockwell B55 hardness and robust 70,000 psi tensile strength, it delivers long-term durability in construction, agricultural, and marine settings, effectively resisting wear and environmental degradation.
Specification Summary & Compliance
This carriage bolt adheres to precise dimensional tolerances, including a Class 2A thread fit and UNC coarse thread specifications for consistent performance. It is manufactured in compliance with ASME B18.5 standards, ensuring interchangeability and reliability. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) requirements, confirming its safety for use in regulated industries and commitment to environmental responsibility.
