One of the things that most DIY oriented people use a lot is screws. For those of you who do not do DIY very often, there are a few things that you might not know about Self Tapping Screws that could put a real damper on things if you get the wrong screws for the job.

Thickness

If you take a look at screws in your local hardware store you will see that they have different diameters. This means that you have to make sure you have the right size drill bit if you are going to be making holes for the screws. You also need to make sure that the thickness of the screws that you get is right for the material you are going to be driving them into. If you get ones that are too large you are going to stand a good chance of splitting the material.

Heads

There are three different kinds of heads on screws. Some of them are star shaped. This means you will need a Philips screw driver to insert them. Others have a single slit in the head for the screw driver. You will need a flat headed screw driver to insert this kind of screw. The last kind of screw had a square hole in the head. You will need an Allen key to be able to use this kind of screw and you will need the right sized Allen key as they come in different sizes too.

Thread

The different sizes of screw will have different sized threads. You can even get different threads on screws of the same size. Make sure that you correctly match thread size and screw size to the hole you have to make sure that the screw will actually go in.

Coatings and composition

You can also get screws that are made of different materials and are coated with different materials. This is so that they can be used in different environments. Some kinds of materials, wood for example, will react with the screw and cause it to erode faster and some will even cause some dreadful looking staining. So you have to make sure that you get the right screw for the job.

As you can see, screws are not just one shape and form. They come in a variety of variations. Each one will fit into only one kind of hole and will be just right for one use. You will also need to make sure that you have the right tools for the job. If you do not have the right drill bit to make the hole then your screws are useless. If you do not have the right screw driver or Allen key then you may as well give up and go home. Screws are a very specialised fastener and you have to be absolutely sure that you have the right kind of Concrete Screws for the job at hand or you are going to have to go back and find the right ones or give up.More information, please visit: http://www.din571.com/
