Can You Use Torx Instead of Hex

Torx keys feature a six-pointed star-like design instead of having six flat sides of a hex key. Unlike hex keys, which typically have a hexagonal cross-section throughout their length, Torx keys often have a circular cross-section, with the Torx form appearing only at the tool’s ends.

The question is, can you use Torx instead of using hex? Continue reading this article if you want to know more.

Can You Use Torx Instead of Hex?

It is not recommended to replace a hex key or Allen wrench with your Torx screw. On the other hand, Rogue DIYers appear to believe it’s a great idea. Check out the table chart conversion of Torx to hex.

This article includes the hex sizes that match the standard and most popular Torx sizes, ranging from T7 to T40. The Torx are also converted to Allen key sizes in imperial measurements. With that in mind, the T9 Torx size will not work with any of the SAE hex sizes. It is, however, a perfect fit for the metric dimension of 2.5 mm. (Read Can I Use Impact Sockets With A Ratchet)

Why Torx Wrenches Aren’t a Good Allen Wrench Substitute

The quick answer is that a hex screw head will destroy your Torx wrenches. A Torx is prone to bending and snapping if they don’t fit firmly inside the screw head. Because each branch in the star only has a single contact point inside a hex screw, the Torx points will bend oppositely.

Furthermore, it’s no secret that using the wrong bit increases the risk of the screw getting stripped. So it is advisable to use the appropriate type and size of the bit when attaching a screw into place. You’ll notice that by doing so, your tools will last longer. Furthermore, your gear will be less likely to fail.

But if you still want to take the risk and use Torx instead of hex, check out the conversion below:

Each Torx to Hex Conversion

  • T7 = 5/64″
  • T8 = 3/32″
  • T9 = 2.5 mm
  • T10 = 7/64″
  • T15 = 1/8″
  • T20 = 5/32″
  • T25 = 3/16″
  • T27 = 5 mm
  • T30 = 7/32″

T7 is the smallest Torx socket size, and it fits a 2mm hex. T7 is just shy of 5/64′′ in the imperial measurement system. T8 is the only Torx size that does not have a metric equivalent. This is frequent with smaller Torx sizes, as they are more exact than hex keys of the same size. In the case of T8, it will function in place of 7/32′′ hex size.

T9, likewise, has no analog on the other side. In metric, though, 2.5 mm is an exact match. T10 reduces perfection to a hex size of 7/64′′. It does, however, join the ranks of Torx wrenches that lack a hex size.

When you get to T15, it has the same size as 1/8′′ hex. T20, on the other hand, is about equivalent to 5/32′′. T25 is the first Torx size that has both SAE and metric equivalents. T25 can be inserted into 3/16′′ or 4.5 mm holes. T27 is a Torx size that fits snugly inside a hex size of 5 mm. T27, unlike its predecessors, does not have an SAE equivalent.

The hex counterparts become less fit as the Torx sizes increase. Torx wrenches frequently lie between hex sizes because their size increases in significant increments. T30, for example, is a good fit for 7/32′′ and even 1/4′′.

It is, however, a little too big for a 5.5 mm hex. On the hex side, the only option for T40 is 9/32′′. T40 is a bit too big to substitute for 1/4′′ or 6.5 mm hex sizes.

Torx or Hex? Which Is the Better Option?

When it comes to Torx screwdrivers, hex nut, and bits, star sockets, and screwdrivers, better is probably not appropriate. However, each one has its benefits, even though there is a minor difference between the star and Torx screws, otherwise identical. (Read Split Beam Torque Wrench How It Works)

1. Convenience

Hex sockets are the most common among them, making Allen wrenches easier to come by. Replace Torx bits, star screwdriver, or bolts with hex sockets if star screws on a device. This makes it easier to find the correct Allen wrench and remove it as needed. This is even though screwdrivers and Torx wrenches are growing more popular.

2. Security

However, switching to security Torx sockets provides superior protection if you want to make it more difficult to disassemble your gadget or item. Due to the pin configuration, this screw is riskier to remove without the correct tool. Of course, if your device has such sockets, someone who takes it may find other alternative ways to get inside.

3. Type

As previously stated, the distinctions between Torx and Star are pretty tricky to spot because they perform the same functions. Star sockets and bits, on the other hand, may have a slight advantage because of how they use non-Torx designs. This means they may employ advanced technology to assist you in manipulating Torx sockets for easier removal.

What are the Benefits of Torx Versus Hex?

The Torx design enables more torque to be applied than a standard hex socket head of comparable size without destroying the head or the tool. If the right Torx bit is used with the bolt, a Torx head can accept more torque for a specific size bolt than a hex head.

It works on the same tool as a Philips head screw versus a slot head screw. The Torx pattern provides a larger bearing surface area, which allows the torque force to be distributed more evenly.

So, what’s the difference between the two? Torx is a licensed product, so manufacturers must adhere to their part printing. (Read Three Point Screwdriver Guide)

What’s the Difference Between a Torx and a Torx Plus Screwdriver?

Torx Autosert correctly guides the driver bit into the recess, resulting in a self-centered engagement action. Torx Plus is a high-torque transmission system. This implies that higher torques in sizes can tighten fasteners securely without causing additional tool wear and tear.

Remember that each design has sub-types, the most notable of which is the twelve-point hex socket, which has a larger surface area and a tighter grip than the conventional six-point version. You’ll want to double-check if you have the right tool for inserting or withdrawing design subset screws or bolts. (Read What Can I Use Instead Of A Screwdriver)

Again, using Torx as a substitute for hex is not recommended, but you can still take the risk.
