Range of access – Allen™ wrenches that feature a hex ball end can allow fasteners to be accessed from angles other than directly in the same plane as the fastener. This can simplify assembly & disassembly in close quarter conditions. Torx screws are typically used in vehicles, motorcycles, bicycles, computer systems, hard disk drives and consumer electronics. The unusual star-shaped head makes them far more secure than regular flat-head or cross-head screws and allows higher torque transmission so screws and bolts can be tightened more securely. Torx Screwdrivers Torx is the trademark for a type of screw head, developed by Camcar Textron in 1967. It’s characterised by a distinct, 6-point star-shaped pattern and is often called a ‘star screw’ that requires a ‘star screwdriver’ with a ‘star bit’ to tighten and untighten them.

This design made improvements on the original which enabled higher torque to be applied while minimising wear.

AudiTorx is a tamper-proof fastener where a convex and smooth fastener head is topped with a break-away Torx drive that snaps off when the engineered torque is reached, leaving a rivet-like bolt head that cannot be easily removed. The main application for these fasteners is in the railroad industry. [29] External (inverted) Torx [ edit ] External Torx driver By design, Torx head screws resist cam out better than Phillips head or slot head screws. [1] Whereas the tendency of Phillips drivers to cam out under excessive torque has been listed as a feature preventing damage to the screw-head or driver, [5] Torx heads were designed to prevent cam-out. The development of better torque-limiting automatic screwdrivers for use in factories allowed this change. Rather than rely on the tool to slip out of the screw head when a desired torque level is reached (which risks damage to the driver tip, screw head, or workpiece), torque-limiting driver designs achieve a desired torque consistently.

But there are many additional, specialised screw-types including Torx screws. What is a Torx Screw? Tether-ready designs – These Allen™ wrenches include an opening on the handle which can be used to attach a tether that can secure the wrench to the user or to a fixed object such as a scaffold. This feature helps prevent the wrench from accidentally falling into a work area and causing injuries or equipment damage. This feature is useful when the tool user is working on an elevated platform. This article needs additional citations for verification.

AW drive is a hexalobular-type screw head similar to Torx, with a tapered profile to aid in centering, developed by the Würth Group in Germany. [30] It is available in five sizes: AW10, AW20, AW25, AW30 and AW40. [31] Gallery [ edit ] 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.Pressure points – the hex design of the Allen™ screw distributes force from the tool against 6 surfaces compared with 4 for the Phillips head screw and 2 for the slotted screw. This makes it easier to loosen or tighten these fasteners and can make it less likely to strip or damage a fastener while loosening or tightening.

Allen™ screws and wrenches are not the be-all-end-all in the world of fasteners and tools. Some complaints focus on the tool size being too small to allow for one to apply sufficient torque in all cases. Also, inferior materials used in the manufacturing of either the wrench or the screw can render them easy to damage in spite of the increased number of pressure points. But they are still popular more than 100 years after William G. Allen™ filed for his patent and will likely be here to stay for the foreseeable future. Summary Besides the common types described earlier, Allen™ wrenches are available with other features that improve safety or increase convenience for using the tool. Size and weight – Allen™ keys tend to be smaller and lighter than the equivalent tools used to apply other fastener types, making them easier to carry. This can be an advantage for applications where mobility is important such as with cyclists that might want to carry a bike tool kit along on a ride. Torx screwdrivers have distinctive 6-point star shaped head which mate perfectly with appropriately sized screw heads. The unique Torx design means that there is less likelihood that the screw head will be stripped or the screwdriver damaged. Torx screwdrivers can last up to ten times longer than regular screwdrivers due to the resilience of the design.
