What is the structural screws? whether alternative corner with black screws?

Greetings to you friends, comrades, experts, builders, carpenters and joiners, and all those good people who are interested in my channel!
Today I want to make out an interesting, in my opinion, the topic - What is the structural screws and what they eat! And also we will look at a "favorite" all fastening element - corner (Reinforced in the best case) on black self-tapping screws.

You agree that it is one of the most popular fasteners, when building a house, are screws for wood. And how nails? - Many ask me. In most cases, various compounds nails gave way more reliable fastening elements - screws, despite the fact that until recently without them can not do many masters. But also self-tapping screws are not standing still and develops. With relatively recently, appeared on the market and already densely applied all experienced builders (you may correct me in the comments) construction screws.

construction screws

largely outperform universal screws and ordinary screws for wood. Purpose of construction screws - to work with all types and grades of wood. Unique structural screws lies not only in their geometric differences that can be seen visually, but also their mechanical properties. Ability maximum deformation during bending without fracture, is caused by the perfect balance of strength and ductility of the steel.

In simple words, structural self-tapping screws It is also an important feature as that of the ordinary nailThat it is impossible to break down at a bend! And this is an important quality allows the data to self-tapping screws power structures. A thread geometry and a special coating, as well as tech milling machine, Directed smoothly along the screw wood fibers, reducing the resistance during tightening. This ensures minimal effort and less wear of the screwdriver.

The main advantages of structural self-tapping screws:
1. The versatility when working with different materials;
2. Ensure maximum safety and reliability of connections during installation of wooden structures;
3. Stabilizing double angle, which is located under the cap screws, provides a tight screwing;
4. Slot Torx retain and protect bit from rotating;
5. unique thread form revolutionary mill;
6. Not crack the wood for the boundary screwing.
7. Sönke notches under the head of the screw head allows perfect drown in wood;
8. Groove on the tip of the screw reams timber, not allowing it to split, which is especially important when working close to the edge!

Now briefly about corner (Possibly reinforced) planted on black self-tapping screws. Why briefly? - but because the topic has long been all moth and discussed hundreds of times. On the internet you can easily find hundreds of articles and reviews about that Do not use the black screws in the frame structure and the attachment of the support structures, and roof system or farms.
Below are just a few of horrific pictures of a survey of homes built by amateurs "black screws".

But before that I want to tell you, if anything at all, in this article, such a fastening element as area with black screws. Myth walks among builders and customers that construction screws more expensive many times than the compound using corner bolted to the usual black screws on wood.

I will try to dispel this myth in my next article with a detailed calculation of these two fasteners.
