Professional Applications & Engineering Value
This Grade 2 zinc-plated steel carriage bolt delivers exceptional value in construction and industrial fastening applications where vibration resistance and security are paramount. The square neck design eliminates the need for additional locking mechanisms by positively engaging with materials during tightening, preventing rotation that compromises joint integrity. The fully threaded UNC coarse thread configuration ensures rapid installation in wood, metal, and structural assemblies while maintaining 60,000 PSI tensile strength under dynamic loads. The zinc plating provides essential corrosion protection for outdoor equipment, agricultural machinery, and building frameworks exposed to environmental elements.
Specification Summary & Compliance
Manufactured to precise dimensional standards including 3/8"-16 UNC coarse threads with Class 2A thread fit for consistent mating performance. Complies with ASTM A307, SAE J429, and ASME B18.5 specifications ensuring interchangeability and reliability. Meets RoHS 3 (2015/863/EU) compliance for environmental safety and restricted substance management.
