- Effective anti-rotation locking provided by the integrated square neck, which secures the bolt during tightening and use.
- Wide, rounded head design distributes clamping force evenly, reducing surface damage and improving safety.
- Coarse UNC threading allows for faster installation and better performance in wood and soft materials.
- Consistent dimensional accuracy with Class 2A thread fit, ensuring easy assembly and interchangeability.
- Compliance with industry standards including ASME B18.5, RoHS 3, and REACH, guaranteeing quality and environmental safety.
Professional Applications & Engineering Value
This Grade 5 zinc-plated steel carriage bolt is engineered to address common industrial challenges such as vibration loosening and material degradation. The square neck design locks securely into materials, preventing rotation during installation and under dynamic loads, which is critical in construction and heavy machinery. The fully threaded UNC coarse thread ensures quick, reliable fastening in wood, metal, and composite assemblies, reducing labor time. With a Rockwell C25 hardness and robust zinc plating, it resists corrosion and wear in outdoor or humid conditions, making it ideal for structural frameworks, agricultural equipment, and transportation applications where durability and compliance with ASME B18.5 standards are paramount.
Specification Summary & Compliance
This carriage bolt features precise Class 2A thread fit and adheres to UNC coarse threading standards (1/2"-13 thread size) for consistent performance. Manufactured in compliance with ASME B18.5 specifications, it ensures dimensional accuracy and reliability. The product is also RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting environmental and safety regulations for industrial use.
