Professional Applications & Engineering Value
This heavy-duty carriage bolt delivers critical engineering solutions where vibration resistance and corrosion protection are paramount. The 18-8 Stainless Steel composition provides excellent durability in outdoor, marine, and chemical processing applications, while the square neck design mechanically locks into materials to prevent rotation during torque application - eliminating common installation frustrations. The UNC coarse thread configuration ensures rapid assembly in wood, metal, and composite materials, with partial threading concentrating strength where needed most. Engineered to ASME B18.5 standards, this carriage bolt maintains precise dimensional tolerances for consistent performance in structural connections, machinery assembly, and transportation equipment where reliability cannot be compromised.
Specification Summary & Compliance
This carriage bolt features a 5/16"-18 UNC thread with Class 2A fit tolerance for precise engagement, manufactured to ASME B18.5 dimensional specifications. The product maintains compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. Mechanical properties include 70,000 psi tensile strength and Rockwell B55 hardness, ensuring consistent performance across industrial applications.
