How to recognize concrete nails?
Concrete nails are characterized by a specific structure of the shaft, which is intended to facilitate the penetration of the nail into the structure of the material and prevent the formation of resistance during assembly work. The market offers standard, knurled, rolled or backed concrete nails.
The second, no less important factor is the material from which the nails are made. It should be taken into account that construction materials are largely exposed to atmospheric, physical and mechanical factors that increase the degree of wear of the elements used, which in the case of concrete nails is of great importance in the context of the durability of the entire structure.
For these reasons, alloys are used to produce nails:
- carbon steel;
- stainless steel;
- protective coatings (galvanizing).
Thanks to these treatments, concrete nails are characterized by high strength, which allows them to penetrate concrete, bricks, steel and hardwood.
Concrete Nails - Application
Despite the names, concrete nails are also used for other types of materials where durability of the connection, great depth of penetration, and safety considerations are required. Concrete nails can be found in formwork structures (formwork), in fastenings of external wall coverings of buildings, as well as holders for conducting technical installations.
There is no need to drill holes in the work surface before driving a nail, a perfect example of which is the use of concrete nailers. Nails should only be purchased from a reputable wholesaler that can boast cooperation with the best manufacturers. Thanks to this, customers gain certainty that the products comply with national and European standards.
How to choose the right length of concrete nails?
The length of a nail selected for specific tasks is closely related to its anchoring depth, which ultimately determines the quality of the fixing. As a rule, a nail that can be inserted deeper into the material structure is able to carry greater loads. However, it should be remembered that in the case of a deep nail embedding, undesirable side effects may occur.
For example, the number of correctly performed installations may decrease due to damage to the nail. As a result, more energy would have to be applied to the installation to achieve the expected effect. This problem does not occur in the case of nailers, because most of them are equipped with automatic adjustment of the application force.

The choice of nail depends on the expected holding value. Its value is influenced by the nail diameter and the depth of embedding. Therefore, these should be the main criteria, predisposing given nails for planned applications.
Concrete Nails Rawlplug SC40II 25mm
Rawlplug SC40II 25 mm concrete nails are equipped with smooth shafts, which is to ensure low resistance during installation. Additional protection against loss or destruction of nails, e.g. due to moisture, is the connection of products with plastic.
The shape of the nail increases the ease of attachment. Additionally, the nails can be used in most leading brand devices.
