- Environmental regulation compliance meeting RoHS 3 and REACH requirements for safe, sustainable usage
Professional Applications & Engineering Value
This 1/2"-13 UNC carriage bolt delivers critical engineering value through its 18-8 stainless steel composition and specialized design. The square neck securely locks into materials during tightening, eliminating rotation in wood-to-metal and structural steel applications. With partial threading and coarse UNC threads, it provides superior grip in soft materials while allowing unthreaded sections to bear shear loads. The rounded head profile offers a finished appearance while minimizing snag hazards. These features make it ideal for construction, agricultural equipment, trailer manufacturing, and industrial machinery where vibration resistance and long-term corrosion protection are essential.
Specification Summary & Compliance
This carriage bolt maintains Class 2A thread fit tolerances per UNC standards with precise dimensional control per ASME B18.5 specifications. The manufacturing process ensures consistent 7-1/2" length, 1/2" diameter, and 1" minimum thread length. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and restricted substance adherence for global industrial applications.
