Fasteners are an integral part of all construction, repair or finishing work. For fastening and fixing soft materials - linoleum, drywall, wood, you can use self-tapping screws or ordinary nails. But if you need to fasten or fix harder materials, such as brick, concrete or stone, then these fasteners will not work here.
Here you will certainly need some kind of stable support that can provide the necessary degree of fixation and the desired level of rigidity, as well as high resistance to various loads. In such cases, the use of fastening materials such as driven anchors is a viable solution.
The drive-in anchor is a cylindrical expansion sleeve with a thread cut inside and an external expansion zone consisting of four segments. After installation in a pre-drilled hole, the driven anchor is unclenched due to screwingfastening part, which ensures the reliability of fixation.
The use of such a fastener as a drive-in anchor is relevant for sheer installation of heavy structures and massive interior elements, as well as when installing window frames, false ceilings and door frames. As a rule, the outer side of the spacer sleeve is knurled, which increases the adhesion to the hole surface. But it can also be smooth. To secure heavy objects, it is more advisable to use the first option.
Drive-in anchor, made of high-strength steel, is designed to withstand significant mechanical loads. It is appropriate to use it for fixing heavy gate consoles, brackets and other massive metal structures. In everyday life (for example, when repairing or decorating the interior), it is more logical to use a driven anchor made of brass. Since brass, being a fairly soft alloy, is more susceptible to deformation than steel. Due to this, a driven anchor made of such material will not create microcracks near the expansion zone.
Although the drive-in anchor is the simplest and most popular fastener, there are other modifications of this kind of fasteners. Each of them has its own characteristics and purpose. Therefore, one or another type of anchor should be chosen in accordance with the specifics of the work being done. Their only common feature is the presence of a sleeve that acts as a kind of anchor, which led to the name of this group of fasteners.elements ("anchor" in German means "anchor").
In addition to the drive-in anchor, there are also such types of fasteners as wedge and frame. The first type of anchor technique is often used where it is required to install heavy structures on a base with a high material density. For example, in industrial plants or warehouses. The frame anchor is indispensable when it is necessary to fasten wooden structures to a brick or stone surface.
And such a modification as a chemical (adhesive) anchor can be used even in hollow structures. In general, there are no restrictions on the use of these multifunctional fasteners. The main thing is to choose the right type of anchor for certain jobs.
