Is Torx same as hex?
No, they are two very different tools. The Allen wrench or hex key, as it is sometimes called, is a hexagon shape, that is why many refer to them as hex keys. The Torx key has a star shape. So if you are trying to use an Allen wrench on a Torx screw, it won't work, and vise versa.

Socket Wrench or Ratchet Wrench If you have one that will fit in the hex screw hole or hexagonal socket you are working with, a socket wrench may come in handy in place of an Allen wrench. What is this?
What is the advantage of Torx over hex?
A Torx head can... actually accept more torque for a given size bolt than a hex head as long as the proper torx bit is used in conjunction with the bolt! It's the same principle as a philips head screw as opposed to a slot head. The torx pattern has more bearing surface area to spread the torque force over.
Is hex the same as Allen?
Nowadays, there are many instruments to choose from. This article is aimed to help you figure out the difference between an Allen wrench and a hex key. The short answer is “there is no difference”. Really, these two names can be used interchangeably.

Is Torx stronger than hex?
The Torx design allows for a higher torque to be exerted than a similarly sized conventional hex socket head without damaging the head and/or the tool.
Why do Torx screws exist?
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.
What are Torx sockets used for?
It is widely used in the automotive and electronics industries, as well as in motorcycles, bicycle brake systems, and in 3C products, including the iPhone. The popularity of Torx socket screws and Torx socket sets has increased over the years and will likely continue to grow.
Who invented the Torx bolt?
The Torx bolt design was invented and patented by Camcar Textron in 1967. So we know Torx is newer, had the hindsight to see the pitfalls of the hex design, but why is it specifically better?
What is the drive angle of a Torx bolt?
The drive angle is the primary driving force behind why a Torx bolt is able to handle more torque before stripping. A hex bolt relies on a 60 degree angle while the Torx bit relies on a 15 degree angle.
When were hex bolts invented?
The Torx bolt design was invented and patented by Camcar Textron in 1967.
What size Torx fits SAE?
With that being said, torx size, T9, won’t doesn’t really work with any of the SAE hex sizes. However, it’s actually a perfect match for metric size, 2.5 mm.
What size wrench fits T27?
In regards to torx size, T27, it fits closely inside of hex size 5 mm. Unlike it’s preceding size, T27 doesn’t really have an SAE substitute. With the larger torx sizes, the hex counterparts become less straight forward. Since the torx wrenches start increasing in size a large increments, they often fall between to hex sizes.
Do Torx tips bend in the opposite direction?
Given that the inside of a hex screw only provides a single contact point for each branch in the star, the torx tips will likely bend in the opposite direction. Also, it’s no secreft that using an inappropriate bit will increase the the possible of of stripping the screw.
Does T8 have a metric counterpart?
Moving on to T8, this torx size doesn’t have a metric counterpart. This isn’t uncommon at the smaller torx sizes as they are offer more precise than similarly sized hex keys. In the situation with T8, it will work in place of hex size, 7/32″. Similarly, T9 doesn’ t have a counterpart on the imperial side. But for metric, it’s a perfect match ...
Is T40 hex too large?
However, it is a bit too large for 5.5 mm hex (still recommend that you try). For T40, you’re only option on the hex side is 9/32″.

When was Torx Ttap developed?
An improved version of Torx called Torx ttap was developed in 2005, which features a second recess to create a "stick-fit" engagement (named Frixion Fit), designed to minimize wobbling (named Stable Drive) without pressing and the need for magnetic bits, a feature that can be important to certain industrial users.
Can Torx drivers drive SAE?
Only the proper driver can drive a specific head size without risk of damaging the driver or screw. The same series of Torx drivers is used to drive SAE, metric and other thread system fasteners, reducing the number of bit sizes required.
Can Torx drivers fit into Torx screws?

Why do Torx sockets have straight sides?
The straight sides of the Torx six sided star shaped socket helps prevent camout and require lower end-load than cruciform systems. But wide tolerances can present a loose fit between the driver tool and the screw head socket and the 15 degree drive angle can reduce the tool bit life.
What is a hexagonal socket?
Hex drive fastenings are very well known. A hexagonal socket in the head of a screw mates with a hexagonal tool (Allen wrench) to tighten or undo the screw.
