- Full-thread engagement providing maximum grip length and uniform stress distribution
- Regulatory compliance meeting major industry standards for quality assurance and environmental safety
Professional Applications & Engineering Value
These Grade 2 carriage bolts deliver exceptional engineering value through their zinc-plated steel construction and square neck design, specifically engineered to solve critical fastening challenges in industrial applications. The combination of 60,000 PSI tensile strength and Rockwell B70 hardness ensures reliable performance in structural assemblies, machinery frames, and equipment mounting where vibration resistance and load-bearing capacity are paramount. The fully threaded UNC coarse threading (10-24) allows for rapid installation in wood, metal, and composite materials, while the square neck prevents rotation during torque application, eliminating the need for secondary locking mechanisms. This makes them ideal for construction equipment, agricultural machinery, and transportation applications where secure, permanent fastening is essential.
Specification Summary & Compliance
This 1 1/2" carriage bolt features precise Class 2A thread fit with UNC 10-24 coarse threading and right-hand thread direction. Manufacturing complies with ASTM A307, SAE J429, and ASME B18.5 specifications for dimensional accuracy and performance reliability. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting current environmental regulations for industrial fastener applications.
