Product Description

Carriage bolts, a type of fastener consisting of a head and a threaded rod (externally threaded cylinder), intended to mate with nuts for the secure attachment of two parts with through holes.

Generally speaking, a bolt is used to connect two objects, usually through a light hole, and needs to be used with a nut, which can not be connected individually. Tools generally wrench. The head is mostly hexagonal, generally larger. Carriage bolts used in the slot, the square neck in the process of installation card stuck in the slot, can prevent the bolt rotation, carriage bolts can be parallel movement in the tank. Because the head of the carriage bolt is round, there is no design of the available power tools such as a cross slot or a hexagon, which can also act as an anti-theft function in the actual connection process.
