Have you ever tried to find the right screwdriver for the security screws used on computers, iPods and other electronic equipment? It can be confusing to try to understand how to call these tools, even before you start choosing the electronic tool that you are looking for.

Here are some terms that you may have heard or need to familiarize yourself with that should help you in your search for the proper safety screwdriver.

  • Torx driver: Torx is a brand name used to identify screwdrivers that are neither a Phillips head nor a flat blade. In most cases, Torx screwdrivers have six sides and look like a star.
  • keys: The keys are screwdrivers that look like a flat-blade screwdriver, but with the center of the blade cut, leaving only the two outer edges.
  • Star Bits The star tips are another example of a Torx screwdriver and look like a star at the tip of the screwdriver.
  • Security screwdriver The safety screwdrivers refer to all the items mentioned above. They are specially designed for tamper or security screws used in the electronics industry as well as in certain automotive applications.

    • Now that you have an idea of ​​what these special screwdrivers are called, let's look at the different types. For ease of understanding, I will refer to all safety screwdrivers as Torx drivers.

    Torx drivers use a numbering system that is usually quite easy to understand. The larger the number, the bigger the driver's head. A T8 Torx driver would therefore have a smaller head size than a T9. Torx screwdrivers can also be called hollow trees or solid trees. The numbering system works the same way, but Torx drivers with a hollow central shaft will have the designation "H" at the end. For example, a solid shaft Torx screwdriver will be called T8, while the same hollow shaft Torx screwdriver will be called T8H, where the "H" designates the hollow shaft.

    You can now find these special types of Torx drivers in so-called security bit sets. In many cases, the security bit sets offer you the same comfort as the drivers, but only contain the bits that can be interchanged using a conventional screwdriver handle with a hollow rod allowing the insertion of the bits. bits. The advantage of security bit sets is that they can be purchased cheaply. The disadvantage is their size, as they may not fit into the cramped areas of electronic equipment.

    The keys on the other hand are a little different from the Torx drivers. The name of this safety screwdriver explains how this driver works. This is a two-pin driver that covers a central end of the security screw. Although this type of security screw is not as popular as traditional star screw, it is becoming more common in new electronic equipment.

    Do not forget that manufacturers have put these types of security screws in their equipment for a reason. If you remove these security screws, your equipment warranty will be void. They are also used to ensure that this type of equipment is repaired by trained electronic technicians.
