Professional Applications & Engineering Value
This heavy-duty carriage bolt is engineered to solve critical fastening challenges in construction, agricultural machinery, and transportation equipment. The 18-8 Stainless Steel material provides excellent resistance to rust and chemical exposure, extending service life in corrosive environments. Its square neck and rounded head design work together to prevent rotation when tightening, eliminating the need for secondary locking mechanisms and reducing assembly time. The partially threaded configuration and UNC coarse thread ensure rapid installation and high vibration resistance, making it ideal for securing structural timber, metal frames, and heavy-duty trailers where reliability is paramount.
Specification Summary & Compliance
This carriage bolt features a 5/8"-11 UNC coarse thread with Class 2A thread fit for precise dimensional accuracy and reliable performance. It is manufactured in compliance with ASME B18.5 standards, ensuring consistent quality and interchangeability. The product is also verified as RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for industrial use.
