What is a tap wrench?

A tap wrench is a special wrench that you can use to create fastener threading. It helps in creating internal threading for screws and bolts of different kinds. The tool’s unique design lets you get the job done without any problems whatsoever.

You get to see two types of tap wrenches in general. They can either be a T-handle tap wrench or double-end wrench. Double-end wrenches are also popularly known as bar wrenches. I will go through the double-end wrenches later on in this article.

For now, let’s stick with the T-wrench. Now, this is the most common of both these wrenches. It’s well known for the capability of creating those internal threading on any fasteners, nuts, or bolts. Let’s check out the working process of this tool; this will clear everything out for you.

How does a tap wrench work?

Well, the working mechanism of a tap wrench is pretty straightforward. You don’t need to do a whole lot to use the tool. This is the easiest way you can find to create inner threading on fasteners, nuts, and bolts.

After inserting it into the fastener, you have to turn the tap wrench to create the threading. I will go through the whole process of doing the job in a bit.

There is another way of creating inner threading on screws or fasteners, which is using a machine. But that’s only suitable for factories or companies doing such a kind of job. There is simply no alternative to using this tool for any DIYer or hobbyist.

So, if you are planning to make something that requires custom screws or nuts and bolts, you should check out a tap wrench. Now, let’s get on with how you can use a tap wrench.

How to use a tap wrench?

Using a tap wrench is very easy to follow along. You have to know some basic steps, and you are good to go. You don’t need any experience or training to do the job. Let’s check out the steps very quickly.

  • First of all, you have to drill a hole in the material to use a fastener. You can use any form of drilling; make sure the hole isn’t too large. You have to drill a hole based on the size of the screws you will use on them later.
  • Then, you have to take your tap wrench and find the right bit for the job. This depends on your needs most and what diameter of screws you will use. Based on that, choose the bit accordingly and put it inside the tap wrench.
  • Now, insert the bit into the hole you created on your material. After that, you have to keep twisting the tool as if you were using a screwdriver. You have to use it just like a screwdriver in this case to create that inner threading pattern on the material.
  • Once you are done, you can use the ratcheting feature of the wrench and start rotating the wrench in reverse to get it out of the material.
  • After the wrench is out of the material, you should have a thread pattern inside the material, which you can use for screwing.

As you can see, there aren’t many steps to follow in using the tool. Also, they are very easy to follow along as well. You don’t need any additional tools to get the job done either.

Things to consider while using the tap wrench:

It would help if you considered several things while using the tap wrench to create inner threading. Let’s check them out very quickly here.

  • Make sure you are using the proper drill bit for the project. Without the proper hole size, everything goes to waste in this process.
  • You can’t use the tap wrench for heavier projects. These are suitable with wooden or plastic materials. For heavier projects, you may need to lean towards automatic machines.
  • You will need to consider the size of the tap wrench before using it for a particular project.

Use of double end tap wrench:

Here’s the tap wrench that will meet your inner threading needs for much larger projects. They are suitable when you need larger taps. Unlike the regular tap wrenches, there is no horizontal handle on a double-end tap wrench. They have an interconnected shaft where you see two different taps on each end. That’s where the double-end tap name comes from.

Using a double-end tap wrench is more complicated than using the T-wrench. Also, it’s not that important for DIYers or hobbyists to have this wrench either. You can make do with a regular tap wrench for the most part.


In short, knowing how to use a tap wrench can help you out a lot. Sure, you can get screws and fasteners all prepared. But when you have to work on personalized projects, you may require some custom screws and fasteners. In that case, there is no exception for you rather than using a tap wrench or T-wrench.

Ensure that whenever you buy a tap wrench, it’s the proper size you want to get in your projects. Also, you have to pay attention to the fact that they have the ratcheting function, making the job much easier and more efficient.
