Value Collection R52001244 Carriage Bolt 5/8-11 Unc 8 in

Product Description

The VALUE COLLECTION R52001244 is a 5/8-11 UNC partially threaded carriage bolt with a standard square neck and an 8-inch length under head. Manufactured from 1006-1050 steel with a galvanized zinc-plated finish, this bolt is built for structural fastening applications where corrosion resistance and reliable clamping strength are required. The square neck seats into a matching hole to prevent rotation during installation, eliminating the need for a wrench on the bolt head. Compliance with ASME B18.5 confirms dimensional accuracy for consistent fit across standard hardware and structural assemblies.

This carriage bolt is suited for wood-to-wood, wood-to-metal, and light structural connections commonly found in construction framing, dock and deck assembly, agricultural equipment, and general fabrication work. The galvanized zinc-plated finish provides a baseline level of corrosion protection for outdoor and semi-exposed environments. Installation requires only a nut and washer on the threaded end, making it straightforward for carpenters, ironworkers, and general contractors working in the field or shop.

Key Features

• 5/8-11 UNC thread form with partial threading per ASME B18.5
• 8-inch length under head for deep material stack applications
• Standard square neck prevents bolt rotation during nut tightening
• 1006-1050 steel construction for reliable tensile strength
• Galvanized zinc-plated finish for corrosion resistance in outdoor use

Compatibility

Designed as a standard ASME B18.5 carriage bolt compatible with 5/8-inch through-holes in wood, metal, and composite structural members where a 5/8-11 UNC nut and washer are used on the threaded end.

Installation Notes

Installation is typically performed by carpenters, ironworkers, or general contractors using standard hand tools. Insert the bolt through a pre-drilled 5/8-inch hole so the square neck seats fully and flush, preventing spin. Apply a hardened washer and nut to the threaded end and tighten to the structural specification for the assembly. Follow applicable building codes and load tables when used in load-bearing connections.
