Key Features & Benefits at a Glance
- Superior corrosion resistance from silicon bronze construction, ideal for harsh marine and chemical environments
- Enhanced anti-rotation performance with integrated square neck that locks securely into materials during installation
- Maximum fastening versatility through fully threaded UNC coarse design for consistent engagement across entire length
- Reliable industrial-grade compliance meeting ASME B18.5 specifications for dimensional accuracy and performance
- Wide rounded head design provides larger bearing surface for improved load distribution
- Environmental regulation compliance with RoHS 3 and REACH standards for safe industrial usage
- Precision Class 2A thread fit ensures smooth assembly and consistent torque performance
Professional Applications & Engineering Value
This silicon bronze carriage bolt delivers exceptional engineering value in demanding applications where corrosion resistance is critical. The fully threaded UNC coarse design combined with the square neck feature prevents rotation during tightening, solving common installation challenges in wood, marine hardware, and structural applications. The wide rounded head distributes clamping force effectively, while the silicon bronze material maintains integrity in saltwater environments, chemical processing, and outdoor installations where steel fasteners would rapidly deteriorate. These carriage bolts provide long-term reliability in dock construction, boat building, and architectural metalwork where both strength and environmental durability are paramount.
Specification Summary & Compliance
Manufactured to ASME B18.5 standards with Class 2A thread fit for precise dimensional accuracy. Features 1/2"-13 UNC coarse threading with full thread coverage along the 2" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The square neck measures 0.28" in length and 0.52" in width, providing secure anti-rotation performance in various material applications.
