Here, we’ll show you how to properly attach and use a crowfoot attachment with your torque wrench, so you can achieve accurate tightening results and take your tool game to the next level.

We’ve covered you, from understanding the different types of crowfoot attachments to tips for achieving accurate tightening results. So, let’s unlock the full potential of your torque wrench and tackle those tough jobs with ease.

How to use crowfoot with torque wrench

Different Types of Crowfoot Attachments

Three main types of crowfoot attachments can be used with a torque wrench: open-end crowfoot, closed-end crowfoot, and swivel crowfoot.

Open-end crowfoot

This attachment is handy for tight spaces and awkward angles where a traditional socket or wrench may not fit. The open-end design allows you to apply torque to fasteners without removing other components or parts.

It’s commonly used for automotive and machinery applications. It’s essential to match the right size of the open-end crowfoot to the fastener to ensure accurate tightening results.

Closed-end crowfoot

It has a closed end and is typically used for industrial applications such as pipe fitting and plumbing. The closed-end design allows for a secure grip on the fastener, preventing slippage and ensuring accurate tightening results.

It’s an ideal tool for professional mechanics, construction workers, and other industry professionals who need to work on pipes, fittings, and other tight spaces.

Swivel crowfoot

This type of crowfoot has a swivel joint that allows for greater movement and flexibility when tightening fasteners in hard-to-reach places. It is commonly used in aerospace, construction, and other heavy-duty applications.

It’s important to note that these crowfoot attachments have specific applications and should be used accordingly.

Can you use a crowfoot on a torque wrench?

Yes, a crowfoot can be used with a torque wrench to help you reach tight spaces and hard-to-reach areas to get the job done easily and accurately. This is a great tool that can help you achieve precise torque measurements even in hard-to-reach places.

How to properly attach and use the crowfoot to the torque wrench?

Attaching and using a crowfoot wrench with a torque wrench may seem daunting, but with the right approach, it can be a simple and efficient process. Here is a step-by-step guide for properly attaching and using a crowfoot wrench with a torque wrench:

Step: 01

First, ensure that you use the correct size crowfoot for the fastener you will be working on. A mismatch in size can lead to inaccurate tightening results or even damage to the tool or fastener.

Always ensure that all the tools are in good working condition and clean before use.

Step: 02

Next, align the crowfoot’s square drive with the torque wrench’s square drive. Make sure that the crowfoot is fully seated and locked into place on the torque wrench.

Step: 03

Rotate the crowfoot clockwise for closed-end and open-end crowfoot to lock it into place. For the swivel, turn the swivel joint to lock it in place, and the crowfoot wrench is securely attached to the torque wrench.

Step: 04

Before using the tool, check to ensure the crowfoot is securely attached to the torque wrench. A loose or unstable attachment can lead to inaccurate tightening results and even damage the tool or fastener.

Step: 05

Adjust the torque wrench settings according to the manufacturer’s recommendations or the job’s specifications.

Step: 06

Place the crowfoot on the fastener and apply pressure until you reach the desired torque setting.

Step: 07

Always check torque readings with a torque-checking tool and repeat the process if necessary.

Step: 08

Carefully remove the crowfoot wrench and the torque wrench from the bolt or nut.

Always consult the torque wrench and crowfoot wrench’s manual before using it, as each one may have different instructions.

By following these steps and tips, you can ensure a secure and stable attachment of the crowfoot to the torque wrench and achieve accurate tightening results.

Tips for achieving accurate results when using this combination

Achieving accurate tightening results when using a crowfoot with a torque wrench requires following some best practices and tips. Here are some suggestions for achieving the best results:

Use the correct size wrench

Use the correct size crowfoot wrench for the bolt or nut you are working on. A crowfoot that is too large or small can affect the accuracy of the torque measurement.

Keep tools clean

Keep the both tools clean and free of debris. Any dirt or debris on the contact points can affect the accuracy of the torque measurement.

Adjust the torque wrench settings properly

Ensure the torque wrench is set to the correct torque value for the specific fastener you are working on. Consult the manufacturer’s specifications or refer to a torque specification chart to determine the proper torque value. Different applications may have different torque requirements.

Use the right extension

When working in hard-to-reach places, use the correct extension to reach the fastener. The extension should be the same size and length as the crowfoot.

Use the right technique

When using this combination, it is crucial to apply force to the handle evenly and with a consistent motion.

Check the torque readings

Always check the torque readings on the torque wrench to ensure that the correct amount of torque is being applied to the fastener. If the torque readings are not within the specified range, adjust the torque wrench settings or re-tighten the fastener.

Wear safety gear

Always wear safety gear when using torque wrenches and crowfoot wrenches.

Properly calibrate the torque wrench

A torque wrench that is not properly calibrated can lead to inaccurate tightening results. It is essential to calibrate the torque wrench according to the manufacturer’s instructions and at regular intervals.

Choose right direction

Always use the torque wrench in the direction that it is designed to be used. Some torque wrenches are only intended to be used in one direction, such as right or left.

Take care when tightening fasteners in tight spaces

When working with a crowfoot in tight spaces, it is crucial to use the correct size crowfoot and be mindful of the angle of the torque wrench to ensure accurate tightening results.

Following these tips and best practices, you can ensure accurate tightening results when using a crowfoot with a torque wrench. Remember that safety always comes first, so wear the appropriate protective gear when working with tools.

Does a crow’s foot change torque?

A crowfoot attachment does not change the torque setting on a torque wrench. It simply allows you to access fasteners in tight spaces or hard-to-reach areas that would be difficult to access with a traditional torque wrench socket.

The torque setting on the wrench should still be adjusted to the desired level for tightening, and the crowfoot attachment will transfer that torque to the fastener. So, in short, a crowfoot attachment does not change the torque. It only changes the way you apply the torque.


Finally, using a crowfoot with a torque wrench is an essential step in achieving accurate tightening results. With the proper knowledge and tools, anyone can master the art of using a crowfoot attachment to take their torque wrench to the next level.

Always refer to the manufacturer’s instructions, follow safety guidelines, and calibrate your torque wrench regularly to ensure the best results. With this guide, you’re well on your way to mastering the use of a crowfoot with a torque wrench.
