System introduction
Bolt is a kind of fastener consisting of head and screw(cylinder with external thread),which shall be matched with nut to fasten and connect two parts with through hole.This type of connection is called bolt connection.If the nut is unscrewed from the bolt,the two parts can be separated,so the bolted connection is a removable connection.

The thread is divided into coarse thread and fine thread according to the thread type.The coarse thread type is not shown in the bolt mark.

According to the stress mode of connection,it can be divided into ordinary ones and those with reamed holes.Ordinary bolts mainly bear axial force,but also can bear lateral force with low requirements.The bolts used for reaming holes should match the size of the holes and be used when bearing lateral force.
