Value Collection 489116PS Carriage Bolt 1/2-13 2.5 in Square Neck

Product Description

The VALUE COLLECTION 489116PS is a 1/2-13 carriage bolt with a 2.5-inch length under head, manufactured from Grade 2 steel with a zinc-plated finish. The square neck beneath the domed head resists rotation during installation, eliminating the need for a backup wrench on the bolt end. Conforming to ASTM A307 standards, this fastener is suited for general structural and mechanical assemblies where a clean, low-profile head is required. Licensed contractors, millwrights, ironworkers, and maintenance technicians use this bolt type across a wide range of light-to-moderate structural connections.

This carriage bolt is used in wood-to-wood, wood-to-metal, and light structural steel applications in both residential and commercial construction and maintenance settings. Common installation scenarios include deck framing, fence construction, equipment mounting, and general fabrication work. The zinc plating provides basic corrosion resistance suitable for dry interior or sheltered exterior environments. This bolt is sold individually but subject to a minimum order quantity of 50 pieces per order.

Key Features

• Square neck locks into material to prevent spinning during nut tightening
• Grade 2 steel construction meets ASTM A307 fastener standard
• Zinc-plated finish provides basic corrosion resistance for general use
• 1/2-13 UNC thread for broad nut and hardware compatibility
• 2.5-inch length under head suits medium-depth structural connections

Compatibility

Designed as a standard UNC-thread carriage bolt for use with 1/2-13 hex nuts, washers, and compatible hardware in general structural and mechanical fastening applications.

Installation Notes

Installation is performed by trades including carpenters, ironworkers, and general maintenance technicians. Before installation, confirm the receiving material is drilled to the correct clearance diameter for a 1/2-inch bolt so the square neck seats properly and prevents rotation. Tighten the mating nut with a wrench while the dome head is held flush against the work surface. Follow applicable building codes and torque guidelines for the specific joint type and load requirements.
