Screw on concrete - what it is and what it is for

Screw on concrete is aA variety of screws made of very high quality steel. This is a rod-shaped screw, which is carved with a variable method. This method of threading provides maximum fixation and a high level of adhesion to the concrete wall. The screw has a pointed pointed shaped structure and a head for screwing in a predominantly cruciform shape. Its surface is covered with an anti-corrosive compound, which ensures its long-term resistance to moisture and dampness.

This type of self-tapping screws, depending on thepurpose, has a different length, but in thickness they remain unchanged. They are very convenient to operate, since they assume the containment of large masses, without deforming. In some cases, when it is necessary to install a self-tapping screw on concrete, special dowels are not required for this, but experts recommend using them for greater reliability. It happens that during the installation the screws break.

Self-tapping screws for concrete without drilling

It happens, when there is a need to baitself-tapping into a concrete wall, and there is no suitable tool at hand. In this case, the installation of screws will be significantly complicated, because the concrete wall is difficult to make a hole without a drill. In this case, the "people's" advice will help: you just need to hammer a screw into the wall with a hammer. But it should be borne in mind that this method is applicable only when the used self-tapping is intended to hold paintings or other objects of low weight. For kitchen cabinets, for example, this method does not work, because under the force of weight, the screws will fall out.

In this case, it is better to get a drill and to make the screws in the dowels.

How to screw the screw into concrete

To carry out this manipulation you needdrill or perforator, directly self-tapping screws and a conventional screwdriver. First, a hole drilled to the depth in the wall is equal to or slightly larger than the length of the body of the samorez. In the resulting hole with the help of a screwdriver, the self-tapping screw is inserted directly. For the durability of the operation, it is recommended to insert a small piece of a match or a toothpick into the hole, in this case, the screw is densely wedged into the wall and does not fall out. It should be noted that when screwing the screw on concrete, it is better to use a screwdriver instead of a perforator, since at high speeds the screw can make a hole thicker, which can subsequently lead to its fallout. It is also necessary to pay attention to the head of the screw, if it is a crosshead, then the screwdriver needs to be matched, otherwise the screwing will be delayed.

Application of the screw

So, from all of the above, to becomeIt is understandable that in order for a self-tapper for concrete to stay in the wall for a long time, while restraining certain loads, it is better to use a drill for its installation, and to wall or dowel (if it is intended to contain large masses) or by placing any wooden substrate (suitable for shelves, paintings, etc.).
