Things To Know About Self Tapping Screws

By Cornelia White


Self tapping screws are made to make a hole of themselves in things made of plastic, wood and metal. But this does not mean that it is automated, it still needs and instrument to fulfill its purpose and that instrument is called the screwdriver. To attach two separate materials, these tools are usually used. In households, they are used to attach doors and windows to the frame and sometimes used for roofing.

Equipments which require maintenance are attached by these type of screws in order to make the maintenance a lot easier. Just like the wall type air conditioner, most of its parts are attached by these and once the company will do a yearly maintenance, they will just remove it from the wall by detaching the screws. Disposable materials such as disposable cameras does not have such.

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 will loosen after years and this will make you buy another set of it which should be bigger than the previous size. This is worst to hear that you will be holing your stuff again for a bigger hole. So to avoid this, you need to put a metal insert above the hole and before you screw it.this is to relieve the burden of the screw.

Upon buying, also bare attention with the heads of the screws. There are two commonly available in the stores, the bulge and the flat. The bulge is made to establish a quick and easy access to the attachments. The flat on the other hand is there to establish flatness, this is very important especially for the hinges, using bulged will just block the frame.

As you notice, there are line holes on the head of the screw. These vary depending on what type of screwdriver you got. The one with an x need a philip drive that has a corresponding x shape tips. This is most people are buying because it can just be ran by a flat driver in emergency cases. The flat screw is usually used for thing which need to be very tight and difficult to be opened or detached.

The length of the tips would depend on the thickness of the material. A thin material only needs a short tipped screw while the thick needs longer. If the tip exceeds, this could cause damage.

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.
