    Product Tags


    Stainless steel carriage bolts are divided into large semicircular head carriage bolts (corresponding to standard GB/T14 and DIN603) and small semicircular head carriage bolts (corresponding to standard GB/T12-85) according to the head size. The carriage bolt is a type of fastener consisting of a head and a screw (a cylinder with an external thread), which needs to be matched with a nut to fasten and connect two parts with through holes. Generally speaking, bolts are used to connect two objects, usually through a light hole, and need to be used in conjunction with a nut. Tools generally use wrenches. The head is mostly hexagonal and generally larger. The carriage bolt is used 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 head of the carriage bolt is round, there is no design of available power tools such as cross grooves or hexagon sockets, which can also play a role in preventing theft in the actual connection process.

    Carriage bolts are widely used in electronic manufacturing, machinery and equipment industry, chemical industry, valve industry, medical equipment industry, automobile industry, aviation industry, etc.
