Torque Wrench Question

[matt burnett]

I was wondering if it is possible to use a torque wrench with crowfoot wrenches? Or will it give a inaccurate reading because the fastener is not centered underneath the square drive of the torque wrench? Also does a U-joint and extension combination adversely effect the torque reading? Thanks.

You’ll be fine using a torque wrench with a crowsfoot. The only time it becomes a problem and you should start worrying is say you put a 10 inch or big extension between the crowsfoot and the torque wrench. But even then you might be off a hair but usually its not a big deal.

You wont be off by much, and most torque wrenches are not 100% accurate anyways.

When torquing with a crowfoot wrench put the crowfoot on the wrench at a ninety degree angle. That way you’ll be reading more of the torque transmitted to the bolt, and not just the torque transmitted to the crowfoot drive.
