Professional Applications & Engineering Value
This 5/16"-18 UNC carriage bolt delivers critical engineering solutions for industrial applications where vibration resistance and structural integrity are paramount. The 18-8 stainless steel composition provides excellent corrosion resistance for outdoor equipment, marine hardware, and food processing facilities. The square neck design mechanically locks into materials during installation, eliminating rotation and ensuring secure fastening in wood-to-metal connections and structural framing. With partial threading and coarse UNC threads, this bolt offers superior grip in soft materials while maintaining high 70,000 psi tensile strength for heavy-duty applications. The combination of Rockwell B55 hardness and ASME B18.5 compliance guarantees consistent performance in construction, agricultural machinery, and transportation equipment where reliability cannot be compromised.
Specification Summary & Compliance
This carriage bolt features precision Class 2A thread fit with 5/16"-18 UNC coarse threading and right-hand direction. Manufacturing strictly adheres to ASME B18.5 standards for dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
