If you decide to set DIN 7991 at an excellent price, you will get a few advantages. In general, bolts are one of the most common and main types of fastening in the world and can be effectively used in various fields. They are available in different sizes and from different materials and therefore are ideal for combining various types of devices. Self -tapping screws have obvious advantages over the nails. Here are some of the biggest advantages that you will see when choosing a screw.
Choosing self -tapping screws, you can achieve mechanical advantages. Compared to clogging a nail in the same material, scoring a screw requires less energy. Thus, for those who use manual tools, the use of screws instantly simplifies the project. The same applies to power tools that require less effort and exert less pressure on the engine engine.
Additional force and prolonged fixation
The screws are very durable and have a long service life. This contrasts sharply with the nails, which over time shake. This happens when the materials that are combined with them expand over time and compressed. The screws are designed to eliminate this problem. Your holding time is longer and stronger. And since the screws are very durable, their strength and durability are not a problem. Thus, when the material is ready, he will give him more confidence.
Corrosion protection
Since the screws provide a strong and dense connection with neighboring materials, they are less prone to corrosion. Dense landing prevents moisture and dirt in the worm shaft and holds the worm shaft in place for a long time. Even if the screw head begins to rust, the shaft remains whole and reliable thanks to this protection. This advantage makes screws the best choice for long -term storage than nails.
The advantages of screws are many different sizes and shapes.
Screws are of different sizes and shapes with different thread patterns. So it turns out a product for wood, drywall, metal -plastic, concrete or other materials. The use of a screw of the right type will increase the service life.
Shurups also use different types of heads, which makes them suitable for different types of tools. This will simplify the work because you can use more tools.
