Value Collection CAI503700750-100BX Carriage Bolt 3/8-16 3/4in

Product Description

The VALUE COLLECTION CAI503700750-100BX is a 3/8-16 UNC carriage bolt with a 3/4-inch length under the head, manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance. The square neck beneath the domed head locks into wood or fabricated metal panels to prevent rotation during fastening, eliminating the need for a wrench on the bolt side. This fastener is suitable for structural assembly, equipment mounting, and general maintenance applications across mechanical, plumbing, and electrical trade work. Sold in a minimum order quantity of 100 pieces per box.

This carriage bolt is sized for standard 3/8-inch clearance holes and works with matching 3/8-16 nuts and flat or lock washers. It is commonly used in wood-to-metal connections, equipment frames, brackets, and utility panels in both residential and light commercial settings. The zinc coating provides moderate environmental protection for indoor and sheltered outdoor installations. Licensed tradespeople and maintenance professionals will find this fastener appropriate for a wide range of routine structural fastening tasks.

Installation Notes

Install using standard hand tools; insert the bolt through a pre-drilled clearance hole and seat the square neck firmly into the material before applying a nut and washer from the opposite side. Torque the nut with an appropriate wrench while the head is held stationary by the square neck. Power down or de-energize any adjacent electrical panels or equipment before working in proximity to live components. Follow applicable code requirements, including NEC guidelines where fasteners are used in electrical enclosure or panel work.
