Product Description

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

The carriage bolts are used in the grooves, and the square neck is stuck in the grooves during installation, which can prevent the bolts from rotating, and the carriage bolts can move in parallel in the grooves. Since the head of the carriage bolt is round, there is no design of available power tools such as cross recesses or inner hexagons, which can also play a role in preventing theft during the actual connection process.
