Professional Applications & Engineering Value

This 3/8"-16 UNC carriage bolt delivers critical engineering solutions for industrial applications where vibration resistance and corrosion protection are paramount. The 18-8 stainless steel composition provides excellent resistance to rust and chemical exposure, making it ideal for construction, marine, and food processing equipment. The square neck design mechanically locks into materials during installation, eliminating rotation in wood-to-metal and structural connections. With fully threaded right-hand coarse spacing, installation time is reduced while maintaining superior pull-out strength. These heavy-duty carriage bolts are engineered to withstand extreme conditions while meeting strict industry standards for reliability and safety in demanding environments.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit tolerance and UNC coarse thread specifications. Complies with ASME B18.5 manufacturing standards for carriage bolts. Meets environmental regulations including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) requirements. The 4" length with 0.375" diameter and square neck configuration ensures proper fit and anti-rotation performance in various industrial applications.
