I beg the Case forum to forgive me for this intrusion. I feel this important enough to bring the question here. Can crows foot wrenches be used with a torque wrench and achieve proper torque. Enjoy the weekend!

I see lots of nice looking flare nut wrenches but not a crowsfoot in the bunch. To answer your question if using a crowsfoot i would very seriously doubt it. All the extra beef in a flare nut would give a lot better chance of some accuracy, but then maybe not since your going to add a four foot cheater bar! (ha ha).

Yes and no. They will be able to deliver a consistent and repeatable torque, but it will not be the same value shown on the torque wrench. The torque calculation on the wrench is measured from the center of the nut. The crowfoot socket would increase that distance and the applied torque accordingly.
If you need to use one in that manner, find another nut/bolt the same size and torque it down with a normal socket. Then change to the crowfoot and gradually work up torque setting on the same nut until it turns. This will get you pretty close.
Good luck.

You need to compensate for leverage. Here is a link to a website that calculate the offset for you.

I am a mechanic for my day job and about every two weeks end up using a crows foot or a torque adapter socket on a torque wrench and if you keep the socket 90 degrees from the handle it will torque to what you set the wrench to. If it is in line with the handle in front of the head you will over torque, if behind the head under torqued. Hope it makes sense, and it's kind of a pain with a ratcheting torque wrench to keep it at 90 degrees and not use the ratchet.

I found the article informative Joe. I recall making a wrench several years ago for the late model Harley Electraglides rear axle that allows the proper value as long as you torque @90 degrees.Thanks Fellows
