It\u2019s designed to reduce slippage and wear compared to more traditional types like Philips or flat-head screws. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Torx?utm_source=openai))  \n- Developed in **1967** by Camcar Textron (later part of Acument Global Technologies), it\u2019s now standardized internationally under **ISO 10664**, known in technical terms as a \u201chexalobular internal\u201d drive. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Torx?utm_source=openai))  \n\n---\n\n### How Torx Works\n\n- Unlike Phillips or flat screws, Torx drives allow the tool to apply torque **without cam-out**\u2014that means the driver is much less likely to slip out of the screw head when force is applied. This helps preserve both tool and workpiece. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Torx?utm_source=openai))  \n- Torx geometrically transfers torque more efficiently: its star-shape allows for force to be distributed evenly along its walls rather than concentrating it on corners. This makes Torx screws more durable, especially under high torque. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Torx?utm_source=openai))  \n\n---\n\n### Variants of Torx\n\n- **Standard/Internal Torx**: Identified with \u201cT\u201d (or \u201cTX\u201d) plus a number (T1 through T100). Higher numbers = larger star heads. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Torx?utm_source=openai))  \n- **External Torx**: Here, the fastener head itself is star-shaped, and you use a socket to engage it. Marked with \u201cE\u201d plus a number, like E4\u2013E44. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Torx?utm_source=openai))  \n- **Security / Tamper-Resistant Torx (Tr)**: These have a small pin in the center of the star so regular Torx bits can\u2019t be used. Used to discourage tampering or unauthorized access. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Torx?utm_source=openai))  \n- **Torx Plus**: An updated profile introduced in the early \u201990s (patents now expired) featuring more square walls to allow higher torque and better fit especially for high-use & precision applications. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Torx?utm_source=openai))  \n- **Torx ttap, Paralobe**, and others: specialized variants built for even higher performance (longer lobes, added stability, improved contact, etc.). ([en.wikipedia.org](https://en.wikipedia.org/wiki/Torx?utm_source=openai))  \n\n---\n\n### Where You\u2019ll See Torx\n\n- Common in: **cars, motorcycles, bicycles**, especially on disk brakes, engine components. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Torx?utm_source=openai))  \n- Electronics: hard disk drives, laptops, consumer gadgets. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Torx?utm_source=openai))  \n- In industrial and automated settings, because Torx screws are stronger, more reliable and less likely to strip or wear during machine assembly. ([de.wikipedia.org](https://de.wikipedia.org/wiki/Torx?utm_source=openai))  \n\n---\n\nIf you want, I can also pull up a comparison chart (Torx vs Phillips vs hex vs security types) or show you what tools you need to deal with Torx in everyday DIY or repair tasks\u2014just say the word."
