What is a Torx Screw?

With fasteners, it is often the case that they do not secure things to the maximum extent. Over time they become loose and require replacement. For this reason, Torx were invented that are more durable and can manage torques better than their alternatives. 

This type has a characteristic feature of a star-shaped head that requires a suitable screwdriver. It is often used in vehicles, computers, motorcycles, and bicycles because of its higher level of security. Those screws firmly fasten mechanical parts and make them unmovable. The screwdrivers used for them also last longer than the regular ones because of a lower friction point while unscrewing. 

Because of being that advantageous, these fastening items are gaining more popularity with time. Internal Torx screws are the most commonly used, but external ones are equally popular for the same security reasons.

What are security Torx screws?

One of the things we expect screws to do is to keep things attached for a long period of time. Regular cross-head and slot-head are commonly used. In the long run, they often fail to meet your expectations. On the other hand, security Torx screws are perfect fasteners because of their tamper-proof design. 

Unlike the regular one, a security Torx screw has a pin in the center that provides additional security. It is impossible to remove this fastener without a specific screwdriver. It is a good and relatively cheap way to protect your vehicle or other valuable things from theft.

What is a T15, T20, T25, & T30 Torx screw?

Torx screws have different sizes. You will need a special, suitable screwdriver to install or remove them. T15, T20, T25, and T30 are some of the star sizes. The letter T in front of the numbers signifies the internal trx. T15 is 0.128 inches or 3.25 mm in point-to-point measurements, and M3.5-M4 is the diameter of the screw.

 The point-to-point size of T20 is 0.151 inches (3.83 mm), and the diameter is M4-M5. Regarding T25, this one is 0.173 inches, 44 mm, and M4.5-M5 in diameter. Finally, T30 is 0.216 inches or 5.48 mm. It also has an M6-M7 screw diameter. 

If you have one of those fasteners or all of them, you can buy a 5-piece AKTOO set. Each piece in this set is made of durable steel with magnetic heads. They are easy and comfortable to use because of their anti-slip handles.

Stripped Torx screw removal

If you were making some repairs and accidentally stripped the head of a screw, there is no need to worry. Even when it feels impossible to get a damaged screw out, there are some useful tips and tools you can use to make it happen.

First of all, you should stop doing whatever made your fastener strip. It will prevent further irreversible damage and give you more chances to get a screw out with less effort. Using power tools to remove the star fastener is often not the best choice. It’s because it does not allow you to control the pressure. That technique can do you more harm than good. 

Instead of power tools, use hand tools that give you more control over your movements. If the screwdriver you’re applying does not manage to get the stripped screw out, try to use the one with a bigger head. There is no need to rush, so move the screwdriver slowly and carefully so as not to worsen the state of the stripped Torx.

One of the useful tricks you can try is using a rubber band. You can place it between the screwdriver head and the Torx and hope it will fill in the stripped parts. It is also better to change the current size of screwdrivers to a bigger size for better effectiveness. Suppose you cannot remove the fastener completely. In that case, you can use pliers and turn them slowly in the right direction until it comes out completely. 

The other methods that can help you to remove stripped fasteners involve using a magnet, a hammer, or even heat. Magnets can help you to retrieve the piece if it is stuck deeply in the hole. A popular tip is to use a hammer and screwdriver. For this one, you should hit the screwdriver with a hammer once it is attached to the head. That should make it more loose and easy to retrieve. The heat is also used to loosen the star.

The previous methods require a lot of effort and do not always lead to successful results. For that reason, you can invest in items designed to remove stripped tees. They guarantee an efficient outcome for as little effort as possible.

Damaged Screw Extractor Kit

The RWYMQWT extractor kit for stripped and damaged screws consists of six pieces suitable for any drill and damaged screws of different sizes. It is easy to use. All you need to do is follow two simple steps. First, insert the remover head into the drill and make a hole inside a stripped fastener. For this task, you should use a smaller drill than the damaged head of a screw. 

The second step is to change the drill tip to an extraction head and use it to remove the fastener. You should do this at low speed, slightly pressing the drill to get a desirable result. The extractors in this kit are made of high-speed steel with 63 HRC of hardness. Simply put, this kit is durable and will serve to remove any other stripped fasteners in the future.

Screw Grab

The rubber band method is cheap, but it does not guarantee 100% success. Instead of using rubber bands, you can buy Solder-It screw grabs that are easy and effective to use. Keep in mind that this method will not work with extremely stripped screws. Before applying it to fasteners with damaged heads, you should shake it. 

You may wonder how GRAB works. It simply fills in the stripped parts of the metal surface and makes it easier for a screwdriver to fit. Then it becomes easy and effortless to get the fastener out. If you have no intention of playing with a rubber band and screwdriver, Solder-It Grab is an effective way to save your time and energy.

FAQ

Torx bit socket
Are Torx and Star the same?

Yes, those two words signify the same item. The Torx screw is in the shape of a 6-point star. People often name it “star” for convenience.

What can I use if I don’t have a Torx screwdriver?

Maybe you don’t have a special Torx screwdriver and want to use an alternative method to get the fastener out. Be aware that Torx can be easily damaged without proper tools. However, it is possible to do without them. 

For example, you can try to unscrew Torx screws using a flathead screwdriver. If you have a security type of star, you should place a flat head in the center and turn clockwise. If it does not work and you have a regular Torx driver, you can try to drill a hole in its center. That will make it fit for a security type of Torx. 

One of the alternative methods that might work is to remove stains by using a plastic toothbrush. You need to meld the plastic edge and insert it into the center of the star head. Then you should wait a bit till it hardens. The next step is to move the toothbrush in the right direction and see if it works. However, those alternative methods do not guarantee successful outcomes. That is why a much more secure way is to have professional tools that will remove fasteners without much struggle from your side.

What is the point of the security Torx screw?

Security Torx screws differ from regular ones in their design. They have a hole inside their head, making removing them more challenging without special equipment. Moreover, those fasteners have a 6-point star shape that is more torque-resistant. 

These types of Torx are often used in vehicles, computers, and other machinery because of their ability to fasten joints at a high-security level. They are also much more durable than regular screws. Moreover, this fastener can protect your car or motorcycle from theft.

How do I know what size Torx screws I need?

The simplest way to find out what size of stars you need is to use a ruler, pencil, and sheet of paper. Measure the screw head from one point to another and write down the results. Then look at the Torx size chart and find the measurements you have. This chart will also help you find a suitable screwdriver.
