Professional Applications & Engineering Value

This Grade 5 carriage bolt delivers critical engineering solutions for heavy-duty industrial applications where vibration resistance and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection for outdoor equipment, agricultural machinery, and construction assemblies exposed to harsh environments. The knurled neck design effectively prevents rotation in wood-to-metal and structural steel connections, eliminating the need for additional locking mechanisms. With UNC coarse threading and Class 2A fit, these bolts ensure rapid installation in production environments while maintaining precise alignment in construction fasteners and industrial frameworks. The combination of 120,000 psi tensile strength and Rockwell C25 hardness guarantees reliable performance in high-stress applications without compromising durability.

Specification Summary & Compliance

This carriage bolt features 1/4"-20 UNC coarse threading with Class 2A fit for standard industrial applications, manufactured to SAE J429 specifications for Grade 5 fasteners. The product maintains dimensional accuracy with a 2" length and partially threaded design with minimum thread length of 3/4". Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe use across various industries and applications.
