What is Carriage bolts?<\/h2>\n

Carriage bolts are divided into large round head carriage bolts (corresponding to standards GB\/T14 and DIN603) and small round head carriage bolts (corresponding to standard GB\/T12-85) according to the size of the head. Carriage bolt, a type of fastener consisting of two parts, a head and a screw (cylinder with external threads), needs to be matched with a nut to fasten and connect two parts with through holes.<\/p>\n

Basic Information of Carriage bolts<\/h2>\n

A bolt is used to connect two objects, usually through a light hole, and needs to be used in conjunction with a nut. A single bolt cannot connect. A wrench is generally used as a tool. The heads are mostly hexagonal heads, etc., generally larger. The carriage bolt is applied in the groove, and the square neck is stuck in the groove during the installation process, which can prevent the bolt from rotating, and the carriage bolt can move in parallel in the groove. Since the heads of the carriage bolts are round, there is no design of useful power tools such as cross recesses or hexagon sockets, and they can also play a role in preventing theft during the actual connection process.
