Mounting dowels are a type of expansion plugs. These are basic fasteners, commonly used in the construction and installation industries. They enable attachment to any type of surface: from concrete and wood, through plasterboards, to solid brick or hollow brick walls. Modern products available on the market are characterized by high load-bearing capacity. They can withstand even heavy loads. Expansion pins are most often made of plastic or metal. Are you wondering which dowel to choose for a given mounting case? Read the guide prepared by Onninen wholesale experts.

Types of anchoring dowels in the surface
A dowel is a type of expansion plug. It is a connecting element. It is used in the installation and embedding of screws, bolts or bolts in the wall, floor or ceiling - regardless of the material the substrate is made of. The dowel (pin) is placed in a previously drilled hole. As you screw in the screw/screw or press in the pin, the expansion plug increases in size and fits snugly into the hole. The resulting connection is characterized by very good strength.
There are several types of anchoring dowels in the surface.
- The first anchoring method is friction fastening. The expansion element of the dowel or anchor is pressed against the wall of the hole. As a result, it transfers external loads by friction.
- The second type of anchoring is form-fitting. The dowel has a special form that allows it to be inserted into a given surface or hole. There it twists, taking on a characteristic shape and ensuring a stable attachment. A universal expansion plug designed for various surfaces is often attached in this way.
- The third type of anchoring - material, requires the use of mortar or synthetic resin. These materials are used to bind the dowel to the ground. The resulting connection is highly resistant to loads and damage.
Easier and more efficient installation of windows with metal dowels
Metal dowels are commonly used to install windows and doors in concrete, brick and many other substrates. They are probably used by every company that installs window and door joinery. They influence the quality, comfort, speed and economy of work performed. A metal dowel with an appropriately long expansion zone, made of high-quality galvanized steel, ensures strong, durable and stable mounting. When it comes to the process of installing door frames using dowels, start by drilling holes using a drill of appropriate thickness (adequate to the size of the dowel), taking care not to damage the edges. Then you need to thoroughly clean the holes. For the safety and durability of the entire project, it is recommended to use dowels and screws from proven manufacturers only.
Durable and solid connections with a concrete dowel
Concrete dowel , as the name suggests, is intended for mounting various objects in concrete substrates. It is mainly used in construction works. It guarantees extremely solid, durable and immobile connections. Dowels differ from concrete anchors in that they are more stiff. This means that the object mounted on the dowels cannot move freely. When buying concrete dowels, you must pay attention to the material.
They must be resistant to the destructive effects of external factors, especially moisture. The optimal choice will be stainless steel, and in special cases - acid-resistant steel. The so-called Acid acid is resistant not only to corrosion, but also to aggressive chemicals such as acids and brine. In the case of walls made of currently popular aerated concrete, you can use universal dowels or specialized elements dedicated to this type of substrate.
