The most obvious SAE vs metric equivalent is the size of the Torx bit. These bits come in a variety of sizes and are typically not interchangeable. The smallest of the lot is the T10, which is about the size of a 1/8" hex. The largest is the T47, which is about the size of a quarter. These bits are designed to work in many thread systems. Examples include vehicles, motorcycles, computer systems, bicycles, consumer electronics, and hard disc drives. Tamper Proof Torx What is Tamper Proof Torx?These fasteners also don’t wobble, so they’re suitable for applications that require high accuracy, like electronics and automobile industries. Polydrive (RIBE) What is a Polydrive Screw? The metric system is a good fit for larger distances. It is not as accurate for smaller distances. Tamper-Proof 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 ] Having a good understanding of the difference between an External Torx and an Inverted Torx will ensure that you get the right bit for your project. Both types of screws have similar characteristics, but you'll want to use the type that best matches your needs. The Polydrive fasteners are similar to the Torx system, but the geometry differs sufficiently that the drives are not interchangeable. So, a Polydrive bit can’t be used on a Torx screw, and vice versa. They do the same job, though, and their performance is comparable. Uses of Polydrive (RIBE)

A spline-shaped geometry refers to a series of ridges or teeth on a drive surface, ensuring a non-slipping grip. Unlike the Torx’s star shape, splines offer a continuous, wave-like profile between the tool and fastener. Both the Torx and Torx Plus have a six-point profile design. The difference lies in the geometry: The Torx fastener has a hexalobular or star-headed design. Using a Torx Bit Sizes Chart is a great way to know which size to buy for a specific fastener. The chart can help you understand the difference between metric and SAE, and can also tell you what size is a good fit for the job at hand. It can also help you choose between an external Torx and an inverted Torx. Torx Bit Sizes ChartTorx Plus offers a range of advantages over the Torx tool, which is already far better than other fasteners on the market.

Pozi – versatile Pozidriv screws feature no less than eight points of leverage, providing significantly better grip than the more familiar Phillips head

Like all other fasteners, even Torx screws are available in different sizes. They follow a special ‘T’ sizing for the internal Torx an ‘E’ sizing for the external Torx. The size of the screwdriver or the drive bit must match with the size of the Torx screw. Torx is an innovative fastener system designed to overcome the shortcomings of traditional screw fasteners.

Both Torx and Torx Plus are available on the market. What’s the difference between these two, and where are they used? 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. Hex – hex heads extend beyond the surface of the screw and feature a hexagonal pattern, with a corresponding screwdriver The 15° drive angle of the Torx makes it less effective for high-speed applications and assemblies. If used in high-speed assemblies, the fastener head might strip, delaying assemblies and potentially damaging the assembly and tools used. The improved design enables the Torx plus driver bits to deliver nearly double the amount of drive cycles and bit life.

Slotted Screws – this is the oldest, most traditional form of screw head; a simple, indented line. They will become unusable if the slot burrs over TORX PLUS Long arm L-Keys". Wiha Tools USA. Archived from the original on 7 October 2015 . Retrieved 14 July 2016.
