Value Collection CAI505005000-025BX Carriage Bolt 1/2-13 5in

Product Description

The VALUE COLLECTION CAI505005000-025BX is a 1/2-13 carriage bolt with a 5-inch length under head, manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance. The square neck design locks the bolt in place against the mounting surface during installation, preventing rotation without the need for a wrench on the bolt head. This fastener follows Unified National Coarse (UNC) thread standards and is measured by length under head per standard fastener convention. It is commonly installed by electricians, plumbers, HVAC technicians, structural contractors, and general trade professionals requiring a reliable through-bolt solution.

This carriage bolt is suited for a wide range of structural and mechanical fastening applications across residential and commercial jobsites. Typical uses include securing wood-to-wood connections, attaching equipment mounting rails, anchoring brackets, and general through-bolting where a smooth, rounded head profile is required on the finished face. The zinc plating provides added protection in mildly corrosive environments. This item is sold in a minimum order quantity of 25 pieces per order.

Key Features

• Grade 5 steel construction for dependable tensile and yield strength in structural fastening applications
• Zinc-plated finish provides corrosion resistance in general-service environments
• Square neck under the domed head prevents bolt rotation during nut tightening
• 1/2-13 UNC thread for broad compatibility with standard nuts and hardware
• 5-inch length under head suits medium-depth through-bolting applications
• Minimum order quantity of 25 pieces supports job-lot purchasing

Compatibility

Designed for use with standard 1/2-13 UNC nuts and washers in general structural and mechanical fastening applications where a carriage bolt profile is specified.

Installation Notes

Install using a standard wrench or socket on the nut side only — the square neck seats into the work material to hold the bolt stationary. Ensure the mounting hole is sized to allow the square neck to draw flush and lock before applying torque to the nut. De-energize any nearby electrical circuits and isolate fluid systems before beginning fastener work in trade mechanical installations. Follow applicable building, mechanical, and electrical codes for the jurisdiction where the fastener is being installed.
