Professional Applications & Engineering Value
This Grade 5 carriage bolt delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection for outdoor and industrial environments, while the square neck design eliminates the need for additional anti-rotation components, streamlining installation in wood-to-metal and structural steel applications. The UNC coarse threading ensures rapid assembly in construction equipment, trailer manufacturing, and agricultural machinery, where the 120,000 PSI tensile strength withstands dynamic loads and stress cycles. The fully threaded configuration accommodates varying material thicknesses in assembly line production, making it ideal for OEM manufacturing and MRO operations requiring reliable, high-strength fastening solutions.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread fit for superior tolerance control and UNC 1/2"-13 coarse thread spacing. Complies with ASME B18.5 specifications SAE J429, ensuring interchangeability and performance reliability. Meets environmental compliance standards including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) for restricted substance control, making it suitable for global industrial applications and regulated markets.
