What is the installation method of the expansion screw? In fact, as long as the correct operating procedures are mastered, the installation method of the expansion screw is not difficult. In order to help you master the essentials, after my practical experience, I have compiled a complete expansion screw installation method for reference learning.

1. Select an alloy drill bit of the same diameter as the expansion screw (tube) of the expansion screw, install it on the electric drill and then punch the wall. The depth of the hole is preferably the same as the length of the bolt. Then, the expansion screw kit is lowered into the hole together. Remember, do not screw off the screw, to prevent the bolt from falling into the hole when the hole is drilled, and not to take it out.

2. After tightening the screw 2-3 buckle, feel that the expansion bolt is tight and not loose, then unscrew the screw, then attach the fixing piece with holes in the fixed object to the bolt, and install the outer pad. The piece or spring washer can be used to tighten the screw.

3, as shown in the figure, 6MM hit 10MM hole; 8MM hit 12MM hole, according to the outer diameter of the expansion tube wall hole. If the brick wall is soft, choose the smaller drill bit. The expansion tube part should all enter the wall. As long as the threaded part is long enough, the sleeve part is deeper and firmer.

4, for the more convenient installation of expansion screws, expansion screw installer application.

The expansion screw mounter structure is specifically designed for mounting an expansion screw in a special environment, and includes a hexagonal cylinder whose inner interface is adapted to an expansion screw, and is characterized in that it further comprises at least one pipe body, and the upper end of the pipe body is fixedly mounted to the hexagonal cylinder The impact drill mounting position is set on the upper part of the pipe body. It can be used to attach impact drills to the air and quickly and quickly tighten the mounting expansion screws or expansion booms 3-6 meters above the ground.

Precautions

The expansion screw must be installed on a relatively hard foundation, and the place where the soft and easy to fall off is unstable, such as the gray joint of the wall.

Remember; do not screw off the screw to prevent the bolt from falling into the hole when the hole is drilled, so that it is not easy to take it out.
