Professional Applications & Engineering Value
This black-oxide steel carriage bolt delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The fully threaded UNC coarse pattern combined with Class 2A thread fit ensures rapid installation in wood-to-metal applications, agricultural equipment, and structural framing. The integrated square neck mechanically locks into materials, eliminating rotation during torque application - a crucial advantage in assembly line operations. With Grade 5 strength rating and 120,000 psi tensile strength, it withstands dynamic loads in trailer manufacturing, machinery mounting, and construction projects where failure isn't an option.
Specification Summary & Compliance
Manufactured to ASME B18.5 standards with UNC coarse threads and Class 2A thread fit for consistent dimensional accuracy. The 7/16"-14 thread size and 1-1/4" length provide standardized compatibility across industrial applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility, while SAE J429 specifications guarantee mechanical performance consistency.
