Professional Applications & Engineering Value
This 18-inch carriage bolt is engineered to address critical challenges in structural and industrial fastening. The 18-8 stainless steel material delivers exceptional resistance to rust and corrosion, making it suitable for outdoor, marine, and high-moisture environments. The square neck securely locks into materials, eliminating rotation during tightening and ensuring stable connections in wood-to-metal applications, trailer construction, and heavy machinery. With a coarse UNC thread and partial threading, it facilitates quicker installation and provides strong grip in soft materials, reducing the risk of strip-out. Its 70,000 psi tensile strength and robust design support long-term reliability in demanding settings, from agricultural equipment to infrastructure projects.
Specification Summary & Compliance
This carriage bolt adheres to ASME B18.5 standards, ensuring dimensional accuracy and performance consistency. Thread specifications include 1/2"-13 UNC coarse thread with a Class 2A thread fit for precise engagement. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in regulated industries without hazardous substances.
