Self tapping screws from the name itself can be able to make a hole of themselves once they are screwed into a wood, metal or plastic. A screw driver is the only tool you need to drive these small instruments. These can be use to attach two different stuff made of varied materials. These are usually used to finish doors and wooden windows.
These screws are very important for highly maintained engines and machines. Like refrigerators, in order to maintain the coolness of its freezer, the freon and other parts must be checked at least twice a year. And to do this, the technician have to unscrew the covers. Things that can still be repaired are using these, but those disposable and company sealed gadgets in which only the companies can open have customized ones.
Now there are sub types for these, the thread cutting and the thread forming. The thread forming is made to make the attachment easier for plastics and other malleable materials. It will just create a very small deformation in order to acquire a hole. But using this unmanageably would make you ruin your product.
While the thread cutting in which it already explained its work by its name. While it is screwed, it will cut everything that covers its path to create a hole. The bad thing about this is that once you are reassembling a thing, it would strip its one pathway to the point that it can hold no more. And so you need to purchase a bigger one in order to get the same tightness as before.
Both screws are prone from stripping, to prevent this, you have to purchase a metal insert and put it under the head of the screw. In this way there is no need to buy for another larger one if you will do the assembling. They are made to minimize stress from the material and from the screw. This insert is very important especially when installing wheels for cabinets.
If you are to buy screws, be mindful with the head. They also vary with there head, let us start with the form, there are bulged circular head and flat circular head available in the market. These head are the most used by people, the flat usually used for things which needs to be flat like the door hinges and the surface of the tables. The bulged one is made to make and easier disassembling for this cannot be too tight unlike the flat.
Then if you notice, you can see lines where you can drive the screws with the driver. There is one which has an x symbol and the other one is just a line. The one with x needs a philip screw driver and the other need a flat driver. Sometime people buy the one with x because it can be driven by both. Unlike the flat, if you accidentally left your flat driver then you cannot do the work.
Do not be too careless on not looking with the length of the tips. You do not want to buy a very long one with your thin plywood. Length will always vary on how deep or thick you want the effectiveness.
Self tapping screws are made for assurance and safety. If this is not used with proper guidance, then this might be dangerous to anyone. A simple mistake would enlarge especially if left unnoticed.
