| crowfoot sockets
Anyone know where to get a good reputable set in metrics? They are extremely useful when used with torque wrenches for open-end tasks.  |

Snap-On sure looks nice, but way too expensive.

So how does this affect the accuracy of the torque reading?
Edit: Never mind. Found the answer. Just measure the distance of pivot points.........

If what your torquing calls for a certain amount i.e. 90 in-lbs. place your crowfoot socket 90 degrees to what you are torquing. This way you don't have to recalculate your torque.

But the pivot points are in different places. Plus, as soon as you do any kind of motion, the measurement is off.
This is all moot as there are cheat sheets out there and the math is pretty simple.
Time to ask a physics teacher, LOL.

What are you guys fussing about?
First you tighten by hand, then use the torque wrench as the final blow.
what pivot point? 90deg?
It torques just like a normal socket.

Many many years ago, i ordered metric crows foot from the Sears catalog. They didn't carry them in store, and i think they still don't. They are made in USA, and never had a problem with them. Don't know if Sears up here still carry's them. they probably would carry them in the Sears in the states.
Honda currently has a recall on 06-07 civics to replace the water pump and/or pulley. The bulletin says to torque the pulley bolts to 10 lbs. They also say its ok to use a crows on the torque wrench.
Not sure if using a crows with a torque wrench will change torqu-ie-ness. Whether it's the original pivot point or the pivot point has been extended a few inches, its still going to need 10 lbs of pull to make the wrench "click", when you set it at 10 lbs.
Its a question for engineers and physics people.

Apparently, we have lots of master mechanics, LOL.

if you are using it to extend the torque wrench, you are increasing the length of the "arm" which is going to multiple the force more. If you install the crowsfoot 90 degrees to the torque wrench, you are not increasing the length of the arm thus no additional torque is added. http://www.belknaptools.com/extcalc.asp http://www.finishing.com/118/94.shtml | |

the difference a crow-foot places on the torque is mostlikely less than the inaccuracy of a prince-auto torque wrench in the first place.
