What is the use method of plastic expansion screw?

The use method of plastic expansion screw is: the drilling depth needs to be slightly deeper than the length of the expansion pipe, because it is afraid that when installing the expansion pipe in the later stage, the expansion pipe cannot be completely inserted into the hole due to some impurities in the pores.

For the installation of expansion pipe, improper installation will affect the installation effect of the product. When installing the expansion tube, it is necessary to know the weight of the item to be installed and the hardness of the installation base, and then choose the appropriate expansion tube. If the installation project is a heavy-duty project, large-size expansion pipe should be selected.

In addition, according to different installation base materials (installation wall materials), products of various lengths, such as concrete, conversion bricks, perforated bricks, etc. More and longer expansion tubes are needed to install fixed objects, and the bearing capacity is determined by the focal length and focal length.

Extended data:

Plastic expansion screws are introduced as follows:

When installing the expansion pipe, first understand the size of the plastic expansion pipe. According to the size, the opening size of prefabricated holes (wall holes with power tools) should correspond to the outer diameter of the expansion pipe one by one, and the length should be 5mm-7mm longer than the total length of the expansion pipe. Then use the inner diameter to match the corresponding screw.

For example, the inner diameter inlet of M8 expansion tube is 6, which becomes smaller and smaller because it depends on the substrate. If it is installed in concrete, it can be installed firmly with 5mm expansion pipe. If it is used in the hard wall base such as transfer bricks, it should be installed with 6mm self-tapping screws.
