Professional Applications & Engineering Value

This 3/4"-10 UNC carriage bolt is engineered to address critical challenges in industrial and construction applications where vibration resistance, corrosion prevention, and structural integrity are paramount. The 18-8 Stainless Steel material offers excellent resistance to rust and chemical exposure, making it suitable for outdoor or high-moisture environments. The square neck design effectively locks the bolt in place, eliminating rotation during torque application and reducing maintenance needs. With a coarse thread and Class 2A thread fit, it ensures quick installation and reliable holding power in wood, metal, and composite materials. Its partially threaded configuration provides enhanced shear strength, ideal for framing, machinery, and structural supports that demand long-term durability and safety.

Specification Summary & Compliance

This carriage bolt adheres to ASME B18.5 standards, ensuring precise dimensional accuracy and performance reliability. The UNC coarse thread with Class 2A thread fit guarantees proper engagement and tolerance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming the absence of hazardous substances and supporting sustainable procurement practices.
