Generally speaking, the bolts used to connect two objects, usually by light hole, need and nut (the nut), can't afford to a single connection.Tool using a wrench in general.The head of the hexagonal top, generally larger.Four square neck carriage bolts used in slot, in the process of installation card in the slot, turn can prevent bolt, carriage bolt can be parallel move in the slot.Due to the carriage bolt head is round, there is no cross slot or hex power tool design are available, and in the process of actual connection can also play the role of anti-theft.

Carriage bolts were developed for use through iron strengthening plates both side of a wood beam. It is commonplace though to use them to bare timber, the squared section givie enough grip to prevent rotation.They are used in many wood connections utilizing the square neck under the round head which will sit into the hole to prevent the head from turning.

Do not drill the holes bigger in the wood parts. The idea with carriage bolts is that you pound them in with a hammer so that the square neck part under the head of the bolt is forced down into the tight hole in the wood. This provides the hold to a) keep the bolt in place during assembly and b) to keep the bolt from turning while using a wrench or socket to tighten the nut from the end of the bolt.

Our business philosophy consists in “ integrity and pragmatic view, quality first, customer first, continuous improvement” and, as such , our company tends to provide you with products with the best price and high-class quality.

When join pieces of wood together using a carriage bolt, the square head on the bolt can change stripped in the hole, making them hard to tighten. To solve this problem, insert a few finishing nails in the hole beside the bolt before hammering the bolt into place. The nails will fill the gaps between the hole and bolt to remain it from spinning.
