When performing many repairs, it is often necessary to use dowels. When this part is driven into the wall surface, a reliable fixing unit arises that is able to withstand heavy loads. Properly hammered dowel is almost impossible to remove from the body of the material in which it is fixed. Let's figure out how to hammer dowels into the wall correctly.
Dowels There are many species. For each case, different ones are selected - it all depends on the task. All dowels are divided into two large groups: universal and expansion.
Spacer dowels include fasteners, the housing of which is expanded during installation. The upper part of the part is usually made of dense plastic, while the core, which is screwed into the sleeve, is made of plastic or metal. Such dowels are mainly hammered into solid walls with solid filler.
The universal plugs can be fixed in the wall, which is hollow. The material of the upper part of the dowel under the action of the rotating force of the core twists and forms a nylon surface that fits snugly to the surface of the hole made in the wall. For fixing insulation used dowels with wide caps.
The dowel length varies widely - from 20 to 120 mm. The same applies to the diameter of parts - from 4 to 20 mm.
One of the most popular fasteners are plastic expansion plugs. The body in such parts is made of nylon, polypropylene or other identical materials. The plug of such an anchor looks figural - there are a lot of sharp protrusions and antennae visible on it, thanks to which the part firmly “sits” in the wall. The expansion plastic dowel is equipped with a metal core that is longer than the outer base. The core is threaded or there are conical formations. Thanks to them, the inside of the dowel, when screwed in, is firmly held in a plastic sleeve and, accordingly, in the wall.
During construction and repair, a dowel with a self-tapping screw or a dowel-nail is most in demand, they can be fixed in different materials. To properly fix them in the wall, providing a quality mount, you must comply with certain conditions. Only at first glance it seems that it is very easy to hammer dowels into the wall. In order not to damage the material, you must follow the rule that the dowel body should not protrude beyond the edge of the wall surface.

It should be noted that the core must be twisted, rather than hammering. Otherwise, the sleeve may burst and lose its fastening properties. This statement is only suitable for the dowel, the core of which is a screw. The nail must be hammered to the stop.
