Professional Applications & Engineering Value
This 316 stainless steel carriage bolt delivers exceptional performance in demanding industrial environments where corrosion resistance and structural integrity are paramount. The square neck design provides crucial anti-rotation capability, preventing the bolt from turning during nut tightening in wood, metal, or composite materials. With its UNC coarse threading and Class 2A thread fit, installation becomes more efficient while maintaining precise tolerances. The fully threaded configuration ensures maximum engagement depth, distributing stress evenly across the entire fastener length. These engineering features make it ideal for structural applications in marine equipment, chemical processing facilities, food processing machinery, and outdoor infrastructure where exposure to moisture, chemicals, and temperature variations would compromise inferior fasteners.
Specification Summary & Compliance
This carriage bolt features precise Class 2A thread fit with 1/4"-20 UNC coarse threading and right-hand thread direction. Manufacturing adheres to ASME B18.5 standards ensuring dimensional accuracy and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental and safety requirements for industrial applications worldwide.
