Product Description:

 

For Bolts: Mechanical parts, cylindrical fasteners with threads with nuts. A type of fastener consisting of a head and a screw (a cylinder with external threads) is required to be fitted with a nut to fasten and connect two parts with through holes. This connection form is called bolt connection. If the nut is screwed off from the bolt, the two parts can be separated, so the bolt connection belongs to the removable connection.

 

 

The carriage bolts are divided into large half round head carriage bolts (corresponding to standard GB/T14 and DIN603) and small half round head carriage bolts (corresponding to standard GB/T12-85). A carriage bolt is a fastener consisting of a head and a screw (a cylinder with external threads). It 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 light holes. They need to be used in conjunction with nuts. A single bolt does not serve as a connection. Tools are usually wrenched. The head is mostly hexagonal head, 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 turning, and the carriage bolt can move parallel in the groove. Because the head of the carriage bolt is round, there is no design of the cross groove or the inner hexagon, which can also play an anti-theft role in the actual connection process.
