Professional Applications & Engineering Value
This silicon bronze carriage bolt delivers exceptional engineering value in applications where corrosion resistance is critical. The combination of marine-grade silicon bronze material and fully threaded UNC coarse thread design addresses common failure points in saltwater environments, chemical processing facilities, and outdoor structures. The integrated square neck provides reliable anti-rotation performance that eliminates the need for additional locking mechanisms, while the rounded head profile offers a finished appearance with reduced snagging hazards. Engineered to withstand prolonged exposure to moisture, chemicals, and atmospheric elements, this carriage bolt maintains structural integrity where standard steel fasteners would rapidly deteriorate, making it ideal for marine hardware, dock construction, and coastal infrastructure projects.
Specification Summary & Compliance
This carriage bolt features precise Class 2A thread fit with 3/8"-16 UNC coarse threading and right-hand direction. Manufacturing complies with ASME B18.5 dimensional standards, ensuring consistent quality and interchangeability. The product meets RoHS 3 (2015/863/EU) compliance for restricted hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, confirming environmental responsibility in its production and use.
