How to use expansion bolts

The use method and principle of expansion bolts:
When using, you must first drill holes of the corresponding size in the fixed body with an electric impact drill (hammer) (this is very important, first ask the size of the bolt when purchasing, and then use the drill of the corresponding size to drill), Then put the bolt and the expansion tube into the hole, and tighten the nut to make the bolt, the expansion tube, the mounting part and the fixed body expand into one body.
