If the hole is not big enough when anchor bolts are pre-embedded, we need to expand the hole to make up for it. At this time, the tool we need to use is a pistol drill to expand it. For the drill bit, we need a bit larger than the thread.

Since Pre-burying anchor bolt is the foundation for the installation of the upper steel structure project, it directly affects the installation quality of the steel structure. Therefore, the accuracy of the pre-burying requirements are very high, so should do a good job of preparing the site work before pre-burying, so that there will be no possibility of deviation.
