what is it called a carriage bolt

The carriage bolt can also be called a square neck bolt. From the outside, it is a square neck connected to a round head, so it is also called a square neck bolt. The carriage bolt is composed of a head and a screw. It needs to be used in conjunction with a nut to fasten and connect two parts with through holes. Another feature of carriage bolts is that the screw rod is a cylinder with external threads. Shenzhen Shenzhen Heat Hardware Co,Ltd stainless steel screw manufacturer specializes in producing carriage bolts.


According to its standards, it can be divided into GB12, GB14, GB801 and DIN603. According to the size of the head, it can be divided into large half round head carriage bolts and small half round head carriage bolts. The corresponding standards for large half round head carriage bolts are GB/T14 and DIN693, and the corresponding standard for small half round head carriage bolts is GB/T12-85. GB801 is a low square neck, choose different types according to actual use

Carriage bolts are rarely used in our daily lives, so where are they generally used? The bolt rod does not rotate because of the square neck, which is easy to fix and install. It is mainly used in some places where countersunk screws are needed. The materials used by screw manufacturers in Shenzhen are generally grade 2 and 5 steel and stainless steel, which are also the most common types of carriage bolts.
