Value Collection CAI505001750-100BX Carriage Bolt 1/2-13

Product Description

The VALUE COLLECTION CAI505001750-100BX is a 1/2-13 UNC carriage bolt with a 1-3/4 inch length under head and a square neck drive style. Made from Grade 5 steel with a zinc-plated finish, this bolt is built for general-purpose fastening where moderate tensile strength and basic corrosion resistance are required. The square neck seats flush into wood or soft material to prevent rotation during installation without requiring a wrench on the bolt head. Electricians, plumbers, HVAC technicians, and general contractors use carriage bolts in equipment mounting, structural connections, and bracket fabrication across residential and light commercial jobsites.

This carriage bolt is suited for through-bolting applications in wood framing, equipment pads, support brackets, and utility strut assemblies. The zinc plating provides a baseline level of corrosion resistance appropriate for dry indoor or lightly protected outdoor environments. The 1/2-13 UNC thread is one of the most common coarse-thread fastener sizes in North American trade work, making replacement hardware and matching nuts widely available. This bolt is sold in minimum order quantities of 10 units per order.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard hex nuts and hardware
• 1-3/4 inch length under head suits medium-depth through-bolt applications
• Square neck prevents rotation during tightening without a tool on the bolt head
• Grade 5 steel provides reliable tensile strength for general structural fastening
• Zinc-plated finish offers basic corrosion resistance in indoor and sheltered environments

Compatibility

Designed as a standard 1/2-13 UNC carriage bolt for general fastening applications in wood, metal channel, and structural assemblies where a round-head, square-neck bolt is specified.

Installation Notes

Install using a standard wrench or socket on the nut side only — the square neck locks the bolt against rotation when properly seated in a matching square hole or soft substrate. Ensure the mating nut and washer are rated for Grade 5 or higher. De-energize and lock out any equipment before fastening in electrical or mechanical enclosures. Follow applicable NEC or building code requirements for structural fastener sizing and torque where specified by the authority having jurisdiction.
