Drill-tail screws are not only used in some engineering projects, but also in home decoration. Compared with other screws, drill-tail screws have the characteristics of direct drilling, tapping and locking, which greatly saves construction time and improves work efficiency. However, the use of drill-tail screws is also to pay attention to certain ways and means to achieve the most ideal fastening effect. Especially for their own renovation of the family, the following to give you an introduction to the future of some small renovations in the home can be their own hands to solve.

Before that, we will introduce the scope of application of drill-tail screws: drill-tail screws are mainly used in the steel structure of the color steel tile fixing on the majority, can also be used for simple construction of thin plates fixed. And different materials of drill-tail screws for different objects, for example: the use of wood is generally iron drill-tail screws, used in steel plates are iron, stainless steel two. The specific use of what material what specifications of the drill-tail screws, or according to the use of the object of the material, thickness and other specific circumstances to choose. The following, to introduce you to the correct use of drill-tail screws.

1、 First need to prepare a power of about 600W special electric drill, check whether there is a problem with the speed of the drill. Adjust the locator of the drill to the right position to ensure that the drill tail screw can be drilled to the correct position.

2、Choose a suitable batch or sleeve (different head type sleeve used for the drill tail screw is different) to install on the electric drill, and then connect the screw well.

3、Be sure to pay attention to: the drill tail screw and the drill must be perpendicular to the surface of the pressed steel plate during installation.

4、Add a force of about 13 Newton (i.e. 13 kg) to the electric drill by hand to make sure the force is on the same vertical line as the center point.

5、Turn on the power switch, the electric drill begins to work, can not stop in the middle, the screw in place should quickly stop down the drill (be careful not to drill down not in place or excessive down the drill).
