General Tech Torque Question

[KVH]

I've seen discussion before, but what's the advice for trying to use a torque wrench in a cramped space with one of those short angle socket extensions, the ones that move or swivel? My guess is that everything becomes completely inaccurate?

On the other hand, straight, rigid ratchet extension pieces that keep the arm of the wrench parallel to the nut or bolt head surface should make no difference?

Extensions are fine. U-joints are not.

It's all approximation anyway; even the torque value is only an approximation to actual fastener load (which is the important bit). A rigid extension has relatively little impact, but you need to support it so it doesn't twist off at an angle.

IMO a swivel socket or U-joint is OK too, as long as you keep the axis of the torque wrench close to the same as the fastener being tightened. 1 or 2 degrees off won't make enough difference to argue about. But any larger deviation is going to reduce the torque applied.

I use a 6" extension on my torque wrench when tightening dead bolts. In theory if I can keep the centerline of the extension on the centerline of the stud, there is no foul. Gets a little shaky at 105 ft-lb

It's a bit of a moot point. I don't know of anyone who uses the universal unless you can't reach the bolt without it. So, if you can't reach it without the universal, you wouldn't be able to torque it without it anyway...!

Now you're just being logical ...
