- Reliable Grade 2 strength with 60,000 PSI tensile strength and Rockwell B70 hardness for demanding applications
- Optimized load distribution from the wide, rounded carriage head, reducing surface damage
- Easy installation and removal with UNC coarse threading and Class 2A thread fit for smooth engagement
- Versatile partial threading allowing flexibility in clamping various material thicknesses
- Compliance with major standards ensuring consistent quality and safety in industrial use
Professional Applications & Engineering Value
This hot-dipped galvanized steel carriage bolt is engineered to address common challenges in heavy-duty construction and outdoor applications, where corrosion resistance and structural integrity are critical. The square neck design effectively counters rotation during tightening, eliminating the need for additional locking mechanisms and speeding up assembly in wood-to-metal or timber framing projects. With a Grade 2 strength rating and UNC coarse threading, it provides reliable performance in high-vibration environments, such as agricultural equipment, fencing, and structural supports. The partial threading allows for secure fastening across varying material depths, while the galvanized coating ensures long-term durability against moisture and chemicals, reducing maintenance costs and downtime.
Specification Summary & Compliance
This carriage bolt features a 3/8"-16 UNC coarse thread with Class 2A thread fit for standard tolerance and ease of use. It complies with ASTM A307 for low-carbon steel bolts, ASME B18.5 for dimensional standards, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safety and sustainability in industrial applications.
