Various fasteners play an important role in construction work. Such elements allow you to reliably fasten individual parts to each other, to make strong frame structures. Currently, there is a wide variety of such retainers. Today we will talk about the features of the self-tapping screws produced by Spax.

Peculiarities

A self-tapping screw is a special fastening element that looks like a thin metal rod with a sharp triangular thread. Such parts have a small head.

Self-tapping screws are increasingly beginning to replace nails . They are more convenient to use. In addition, they provide a more secure and durable fit. With the help of such parts, you can hold together wood, metal objects and many other materials.

Self-tapping screws can be made from different metals . Most often, special high-quality carbon steel, stainless steel, brass are used for them. From above, these parts are covered with additional protective compounds. Phosphated and oxidized components are often used as such substances.

Self-tapping screws can vary significantly in some design features . So, the tip of such metal parts can be sharp and drilled. The first type is used for soft surfaces, the second option is better for working with metal products.

Self-tapping screws made by Spax also have some important features that allow you to make the fixation of the material as strong and reliable as possible.

So, these elements in most cases are created in a four-sided design, which makes it possible to accurately remove wood fibers without damaging the surface or spoiling its appearance.

The products of this manufacturer have a slightly wavy screw part . This design allows for a smoother screwing of the element into the material. In this case, you will need to use a minimum of effort for this.

These self-tapping screws are most often produced with a bit equipped with a cutter . Such fasteners make it possible to fix parts without pre-drilling recesses.

In addition, in the assortment of products of this company, you can find self-tapping screws with a head located at a slight slope. These metal elements will be completely in the material without protruding from the surfaces.

Assortment overview

Currently, the manufacturer Spax produces a large number of different types of self-tapping screws. The most popular among buyers include the following options.

Self-tapping screw for A2 Torx decking . This model is made of high quality stainless steel, the head of the element has a cylindrical shape, without material splitting. The tip of the self-tapping screw is sharpened as much as possible, the external thread runs over the entire surface, except for the middle part. Such samples are used for fastening wooden boards, lining. The fixing thread of the parts allows you to tightly press the top sheets. They allow you to minimize the creaking of the structure after fixing, while ensuring a beautiful appearance - such devices do not spoil the overall design of the wooden structure.

Front self-tapping screw Cut . This variant is equipped with a special lens head. A self-tapping screw is made of stainless steel. It will be an excellent option for fixing facade boards, planken. These elements can significantly reduce the delamination of the wood. They quickly and easily enter wood surfaces without forming small sawdust and other debris, which is achieved thanks to special milling ribs. The parts are coated during creation with anti-corrosion protective solutions, so in the future they will not rust and spoil the overall design of the structure.

Universal self-tapping screw A2, full Torx thread . This lock is also made from durable stainless steel. The head of the part is countersunk. The model is able to significantly reduce delamination and splitting of the wood surface. It is inserted cleanly into the wood using a milling thread. Most often, the universal type is used for wood, but it can work for other materials as well.

Self-tapping screw for floor slabs and eaves cladding . This model is available with double sharpened threads. When created, they are all coated with a special Wirox composition. It provides maximum resistance to corrosion of the device. In addition, this application provides high strength and hardness of the parts. Often such samples are used to fix fences, wind boards. The fixing thread of the self-tapping screws holds the material in such a way that the effect of a vice is created. Creaking of the structure held together by these clamps is minimized. The head is equipped with milling ribs, which greatly simplify the process of deepening the self-tapping screw in the material. They allow the boards to fit as tightly and firmly as possible to each other. The model is also equipped with a special 4Cut tip. It prevents the surfaces from delaminating during the installation of the fasteners.

Self-tapping screw for solid wood floors . The model is used for parquet, lining, timber imitation. Like the previous version, it is coated with Wirox, which provides additional protection against corrosion. This solution is environmentally friendly and safe for humans and their health. It contains no chromium. The self-tapping screw has an unusual geometry and a special Cut tip, such design features help to avoid wood delamination.

How to choose?

Before purchasing such items, you should pay special attention to some selection criteria. Be sure to look at the type of head. It can be hidden - in such options, the head, after installation, is completely buried in the material, it will not protrude above the boards . There is also a semi-countersunk head, it has a smooth transition from the central rod to the thread. Such models, after fixing, completely sink both from the outside and from the inside.

Specimens with a semicircular head have a fairly large pressing surface of the material . This allows the part to be fixed to the surface as firmly and reliably as possible. Semicircular heads with a press washer will be the best option for joining sheet materials. They are distinguished by a slightly increased surface and reduced height.

Truncated cone screws are used for metal structures or drywall. As a rule, such models are coated with a special phosphate protective agent. The hexagonal heads of the self-tapping screws can be fixed only with powerful electric devices with attachments . Cylindrical products can only be screwed into a slightly drilled recess. Be sure to look at the thread type before buying. It can be rare, such models are used for softer materials. Most often, these screws are used for wood, asbestos, plastic. The middle thread is considered a universal option, which is taken to fix concrete pavements, in this case, the elements are hammered into the dowels.

Models of self-tapping screws with frequent threads can also be used to fasten metal thin sheets, while dowels are not needed . Samples with an asymmetric thread type are best used when assembling furniture. However, it will be necessary to pre-drill the hole.

Remember that different models of these screws are designed for different loads. So, in specialized stores you can see individual samples for fixing parquet floors, terrace structures, for solid boards, for tongue-and-groove boards.
