Value Collection 489101PR Carriage Bolt 7/16-14 2 in Square Neck

Product Description

The VALUE COLLECTION 489101PR is a 7/16-14 carriage bolt with a 2-inch length under the head, designed for general-purpose fastening applications in wood, metal, and structural assemblies. The square neck below the domed head pulls into the substrate to prevent rotation during installation, allowing the nut to be tightened from one side without holding the bolt head. Manufactured from Grade 2 steel with a zinc-plated finish, this bolt meets ASTM A307 standards. It is a standard inch-series fastener with UNC (Unified National Coarse) threading and is suited for light- to medium-duty structural connections.

This carriage bolt is appropriate for residential and light commercial construction, woodworking, fencing, deck building, and general maintenance work. Trades including carpentry, general contracting, and facilities maintenance routinely use this bolt size to connect wood members to wood or metal framing. The 7/16-14 UNC thread is a widely stocked size compatible with standard hex nuts, washers, and coupling nuts of the same thread designation. This SKU is sold individually but requires a minimum order quantity of 50 units per order.

Compatibility

Designed as a standard inch-series UNC carriage bolt compatible with 7/16-14 hex nuts, flat washers, and lock washers in general structural and woodworking fastener assemblies.

Installation Notes

Installation is typically performed by carpenters, general contractors, or maintenance technicians using a standard wrench or socket on the nut side. Before installation, drill a clean through-hole sized to allow the square neck to seat flush and grip the substrate. Drive the bolt through the material so the square neck pulls in fully, then thread the nut by hand before applying final torque. Follow applicable building codes and structural load requirements for the specific assembly.
