• Exceptional mechanical strength offering 70,000 psi tensile strength and Rockwell B55 hardness for reliable load-bearing capacity
• Secure anti-rotation performance through integrated square neck design that prevents spinning during installation
• Optimized thread engagement with UNC coarse threading and Class 2A fit ensuring fast assembly and vibration resistance
• Full-threaded convenience allowing maximum adjustability and consistent clamping force along the entire bolt length
• Regulatory compliance assurance meeting ASME B18.5 standards and environmental regulations including RoHS 3 and REACH
• Wide-rounded head profile providing enhanced bearing surface and reduced surface pressure on connected materials

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 1/4"-20 UNC carriage bolts deliver critical performance where vibration resistance and material integrity are paramount. The 18-8 stainless steel composition provides excellent corrosion resistance for outdoor structures, marine environments, and chemical processing facilities. The square neck design mechanically locks into mounting surfaces, eliminating rotation during torque application - a crucial feature for assembly line efficiency and structural safety. With fully threaded right-hand configuration and coarse threading, these bolts offer rapid installation in wood, metal, and composite materials, making them ideal for construction, transportation equipment, and heavy machinery applications where reliability cannot be compromised.

Specification Summary & Compliance

This carriage bolt maintains precise Class 2A thread fit tolerances with UNC coarse thread specification (1/4"-20) and complies with ASME B18.5 dimensional standards. The manufacturing process adheres to environmental regulations including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) requirements, ensuring suitability for global industrial markets. The combination of controlled hardness (Rockwell B55) and tensile strength (70,000 psi) guarantees consistent performance across production batches.
