Detailed explanation of screw connection drawing method

The screw connection drawing method generally adopts the proportional drawing method, and the screw connection is mostly used for the connection of parts with little force. To help you master the drawing method of screw connection, summarize the following content, and use pictures and texts to introduce the drawing method of screw connection in detail.

　　 Use the proportional drawing method to draw the screw connection, the screw-in end is the same as the stud, and the hole of the connected plate is drawn in the same way as the bolt.
