Carbon steel HDG plated Round head carriage bolts Custom Fasteners
Carriage Bolts also called mushroom bolts, round head square neck bolts,it has din standard and customed,they have a square shoulder under a round head and are used with a nut and washer.Carriage bolt have a smooth, round head that has a small square section underneath.And it is up to your requirement about the threaded type ,that full threaded and half threaded also ok to product.
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.
A carriage bolt, coach bolt or round head square neck bolt is a form of bolt used to fasten metal to wood.
It is distinguished from other bolts by its shallow mushroom head and that the shank cross-section of the bolt is circular for most of its length, as usual, but the portion immediately beneath the head is formed into a square section. This makes the bolt self-locking when placed through a square hole in a metal strap, or a round hole in most wood. This allows the fastener to be installed with only a single tool, a spanner or wrench, working from one side. The head of a carriage bolt is usually a shallow dome. The squared section is of the same size as the diameter of the bolt shank, with a plain unthreaded shank.
Carriage bolts were developed for use through iron strengthening plates on either side of a wooden beam. It is commonplace though to use them to bare timber, the squared section giving enough grip to prevent rotation.
Carriage bolts are extensively used in security fixings, such as the Brenton Bolt where the bolt must only be removable from one side. The smooth domed head and square nut below prevent the carriage bolt from being unlocked from the insecure side.

1, the processing cost is low: the cost of hot-dip galvanized anti-rust paint coating than other low cost;
2, durable: in suburban environments, the standard hot-dip galvanized thickness can be maintained for more than 50 years without repair; in urban areas or offshore areas, the standard hot-dip galvanized layer can be maintained for 20 years without repair ;
3, good reliability: between steel and zinc coating is metallurgically bonded to become a part of the surface of the steel, and therefore durability of the coating is more reliable;
4, coating toughness: galvanizing a special layer metallurgical structure which can withstand use in transport and mechanical damage;
5, comprehensive protection: each part of the plating can be plated with zinc, even in depression, sharp corners and hiding places can be fully protected
6, saving time and effort: galvanized coating process than other construction method is more efficient, and to avoid the installation time on site brushing required.
