It’s abbreviated as TR and has a solid post in the center of the screw socket that prevents a standard driver from entering and requires a specialist hollow-headed driver.Īnother security screw design inspired by Torx is the five-lobed star pattern, known as the pentalobe security screw. One design features a “center pin reject,” known as Security Torx, Tamper-Resistant Torx, or pin-in Torx. However, as the drive gained popularity, other drives were invented to fill this role.
In 2017, the latest Torx successor, Torx Paralobe, was released, offering 20% greater torsional strength and 20% greater drive life than Torx Plus.Įarly uses of Torx included as security screw heads, reliant solely on being an uncommon driver type. Its squarer lobes promised to increase drive bit life by 12. Successors to Torx include Torx Plus, which was introduced in the early ’90s. The external drive Torx is less common, however, it has gained some popularity in machine screws and lag screws as an alternative drive head type to hex.
An external drive Torx is marked by a capital letter “E,” followed by numbers 4 to 40 (the numbers do not correspond with internal Torx). Typical sizes are T10, T15, and T25, with inch and metric sized fasteners sharing the same sized drive tools. The internal head sizes are marked by a capital letter ‘T’ followed by numbers 1 to 100, with smaller numbers representing smaller head sizes. They’re also increasingly used in other sectors, such as in building and construction.
Torx internal drive screws are typically used within automotive, IT, and consumer electronics manufacturers. This force distribution allows a higher torque to be transmitted with little likelihood of reaming of failure - either of the driver or the driven screw. With a perpendicular drive angle to the axis of the fastener, Torx drive produces minimal radial force. It’s also less likely to damage the driver or driven screw. Vertical sidewalls maximize tool engagement and produce no cam-out forces to push the driver out of the screw head, resulting in less fatigue as no end load is required. Torx does not cam-out and can withstand higher torques than internal hex at a given head size. It aimed to replace Phillips, which was prone to cam-out, and the internal hex drive, which tended to fail during high torque by rounding off. Torx screws were invented in 1967, by Camcar Textron, as an improvement on contemporary drive types. Torx is available as an internal and external drive although it is most commonly used as a socket within the head (internal). Torx drive is a trademark commonly referred to as star drive or, simply, a six-lobe. Micro-Clamp: 2-piece metal fastener used to secure reinforced silicone tube connections to thermoblocks, outlet valves, membrane regulators, etc.A Torx screw is a six-lobed, star-drive socket or external head.Ī Torx screw is a type of screw characterized by a six-lobed, star-patterned screw drive.The hair pin clip used to secure thermoblock connectors is 5mm. Hair Pin Clips: Metal fasteners used to secure pressure hose connections.The T20 Torx screw is used to secure the Gear Motor to the drive shaft of the brew group. The J-Z-ENA-GIGA use a longer T20 Torx screw with finer threading to secure the brew group drive shaft to the housing however, the drain valve screw is the standard T15. Torx Screws: The T15 Torx screw is used in various locations in every Jura coffee machine, such as the external housing and brew group.These screws need to be removed to open your machine.
