Thus, while Torx offers tremendous advantages over traditional fasteners hex, the Torx Plus is a better option for assemblies that need a tighter grip. Advantages of Torx Plus

For example, if you have a screw with TX size, then you have to use a Torx Screwdriver or drive bit of TX size only. While it’s common to use the terms Torx and star interchangeably, there’s actually a bit of a difference between the two. Much like the Allen wrench, Torx is a trademarked name and refers to a specific brand, whereas star is the generic name (much like hex keys). However, there is a difference beyond just licensing. a b c d e "Chart of Torx fasteners and tools". Wiha Tools USA. Archived from the original on 2015-12-26 . Retrieved 2012-01-14.

Unsourced material may be challenged and removed.The Torx Ttap drive is compatible with the standard Torx drive. However, if you’d like the advantages the Torx Ttap offers, you have to use it with the Ttap drive. The geometries of these drives are exactly the same, except for the additional recess in the screw head’s center. Uses of Torx Ttap Torx and Torx Plus are similar fasteners, but Torx Plus optimizes the design of the original Torx. While both have a six-point connection with the drive head, the Torx fastener allows for a 15° drive angle, while the Torx Plus has a 0° drive angle. This increases the available torque and minimizes wear on the fastener and drive head. Pavlis, Egon (16 March 2010). "When a Phillips is not a Phillips Plus So Much More!". Instructables. Examples include vehicles, motorcycles, computer systems, bicycles, consumer electronics, and hard disc drives. Tamper Proof Torx What is Tamper Proof Torx?

Spanner screws feature a distinctive double indentation in the head. These earned this model its common alternative names – snake eye screw and pig nose screw. The standard Torx driver bit or the key will work on the Torx Plus, but it’s not a perfect fit and can lead to wear or damage. Have you noticed that the effective cross-sectional size of Torx Plus is larger than the regular Torx profile? Compatibility The Torx Plus drive system is another variation of the Torx. It is also known as External Plus. The lobes are more square than the original design. This design allowed for higher torque on the head. The Torx Plus also has five-lobed tamper-resistant variants. This design requires the right tools. The Torx Plus screw is ideal for high torque transfer and low head height applications. In short, applications where the screws must be tightly fastened but also fit in a small space.Another advantage over other types is that star bits are much more efficient when hand-tightening. You can apply a large amount of torque without camming out. Whether you are buying a new set of Torx tools or replacing a broken one, you will need to make sure you buy the right size. There are three standard sizes of Torx, and each one can be distinguished by the T before a number. In addition to these, there are also specialized sizes that are designed for specific uses. You can browse the chart below to find the right tool for your project.

If you need to know which size of Torx is the right one for a specific project, take a look at the Torx bit sizes chart. It will tell you which Torx bits are compatible with which screws. KC Tool Torx screws are commonly found on automobiles, motorcycles, bicycle brake systems ( disc brakes), hard disk drives, computer systems and consumer electronics. Initially, they were sometimes used in applications requiring tamper resistance, since the drive systems and screwdrivers were not widely available; as drivers became more common, tamper-resistant variants, as described below, were developed. [4] Torx screws are also becoming increasingly popular in construction industries. Another advantage is that the Ttap drive doesn’t wobble since the geometry stabilizes the drive. Torx Ttap vs. Torx screws The following is a Torx Bit Sizes Chart for Internal Torx. Two dimensions are important with respect to Torx screws.
