Value Collection R52001263 Carriage Bolt 5/8-11 4in

Product Description

The VALUE COLLECTION R52001263 is a 5/8-11 carriage bolt with a 4-inch length under the head, manufactured from Grade 2 steel with a zinc-plated finish. The square neck design locks the bolt in place against the material during installation, preventing rotation without requiring a wrench on the bolt head. Fully threaded along the shank, this fastener conforms to ASME B18.5 standards. It is suited for general-purpose structural and mechanical fastening applications where corrosion resistance and ease of assembly are required. Licensed tradespeople and experienced DIYers install this type of fastener in a wide range of wood and light structural connections.

This carriage bolt is used in residential and light commercial construction, woodworking, deck building, and equipment assembly. The zinc-plated finish provides basic corrosion protection in dry to mildly humid environments. The UNC thread standard ensures compatibility with standard hex nuts and coupling nuts. It is a practical choice for through-bolt connections in lumber framing, fence assembly, and similar structural fastening tasks where a smooth, rounded head is required on the face side of the work.

Key Features

• 5/8-11 UNC thread size for use with standard nuts and hardware
• 4-inch length under head for through-bolt applications in thick stock
• Square neck design resists rotation during nut tightening
• Fully threaded shank per ASME B18.5 fastener standard
• Grade 2 steel construction suitable for general-purpose structural use
• Zinc-plated finish provides basic corrosion resistance in dry environments

Compatibility

Designed for use with standard 5/8-11 UNC hex nuts and washers in general-purpose wood and light structural fastening applications.

Installation Notes

Installation is performed by inserting the bolt through a pre-drilled hole sized to allow the square neck to seat flush and prevent rotation, then threading a nut and washer from the opposite side. Use the correct drill bit size to ensure the square neck seats properly without excessive play. Tighten the nut with a standard wrench or socket set. Do not use an impact driver directly on the bolt head, as this fastener is designed to be driven by the nut side only.
