Value Collection R52001708 Carriage Bolt 5/8-11 4 in

Product Description

The VALUE COLLECTION R52001708 is a 5/8-11 UNC carriage bolt with a 4-inch length under head and a fully threaded square neck design. Manufactured from Grade 1006/1050 steel with a galvanized zinc finish, this fastener meets ASME B18.5 dimensional standards. The square neck beneath the dome head locks into wood or structural members to prevent rotation during tightening, eliminating the need for a backup wrench on the bolt side. Installers in HVAC, plumbing, electrical, and general construction trades use carriage bolts like this one when securing equipment frames, structural supports, and panel assemblies.

This carriage bolt is suited for through-bolt connections in wood-to-wood, wood-to-metal, and light structural applications. Common install scenarios include mounting equipment bases, securing strut channel assemblies, and fastening access panels or support frames in mechanical rooms. The galvanized zinc finish provides baseline corrosion resistance for indoor and sheltered outdoor environments. The fully threaded shank allows a nut to be run the full length of the bolt, giving flexibility in material stack thickness.

Key Features

• 5/8-11 UNC thread for compatibility with standard hex nuts and coupling nuts
• Fully threaded shank accommodates variable material stack thicknesses
• Square neck locks against substrate to prevent bolt rotation during installation
• Galvanized zinc finish for corrosion resistance in sheltered environments
• Meets ASME B18.5 fastener standard
• Grade 1006/1050 carbon steel construction

Compatibility

Designed as a standard inch-series carriage bolt for use with 5/8-11 UNC hex nuts, washers, and coupling nuts in wood, metal, and structural fastening applications.

Installation Notes

Installation is performed with a standard wrench or socket applied to the mating nut while the square neck seats into the substrate to hold the bolt stationary. Ensure the through-hole is sized to allow the square neck to pull fully flush before applying final torque to the nut. De-energize and lock out any electrical equipment before working in proximity to live panels or energized components. Follow applicable structural or mechanical codes for fastener selection and torque requirements on the nut side.
