Crowfoot Adapters

Belknap’s Crowfoot Adapters are all made to fit your application. They are intended to be used with Electronic Dial Torque Wrenches, Dial Indicating Torque Wrenches, and Micro-Adjustable Torque Wrenches.

While there are four (4) main styles to choose from, we can also custom-make crowfoot adapters in a variety of configurations. If you are in need of a specially designed adapter, give us a call at (248) 348-7800 to discuss your specific requirements. In addition, our Specialty Tools Gallery displays a small sampling of what we’ve produced for our customers over the years.

Crowfoot Adapters
Torque Extension Calculator

Adapters or extensions should only be used in line with the wrench, as opposed to being at an angle, and the actual torque applied (TA) will be greater than the torque reading shown.

Torque capacity of crowfoot will be limited by its hex size and/or the square drive size.
 Most sizes can be made, but safety precautions must always be taken when designing a crowfoot.

Determine the actual torque applied by using the formula to the left.

* Our online Extensions Calculator does all the calculating for you with real-time updates.
