Can the property be driven by expansion screws?

Different communities or properties have their own plans, but whether the expansion screw is a service measure for the community should be considered.

What should we pay attention to when driving expansion screws? First, we should make clear the specific position of screw holes, and secondly, we should pay attention to the depth of drilling holes. If the depth is not enough, there may be sundries in the hole, and the depth of the screw hole is preferably about 5 mm deeper than that of the expansion pipe.

In addition, the expansion bolt has certain requirements for the ground or wall. The higher the hardness, the stronger the bearing capacity, and the appropriate drill bit should be selected according to the size of the screw.
