Thread: Continuously variable torque wrench

What are the differences between torque wrenches which click off (torque limiter) and one that show the applied torque on a scale ?

Do they give equivalent readings ?
Are there any tricks or requirements to using them ?

I've just bought a "Fix It Sticks" set.
You carefully line your eye up for the zero measurement then turn it until the indicator line shows the torque you want on the scale.
I found it gives a nicer more natural feel as you turn the screw and I can see the screw turning a little as it tightens, which I can't with my Wheeler F.A.T. wrench.

I’ll be interested in your experience.

In reality the difference is as good as the combination of the limits of the unit and the accuracy of the user.

Most 'users' prefer some sort of indicating wrench that signals it is at the right setting as it still works out of position, at night or when you can't see the scale or are in a situation where you are looking for movement of everything else rather than the wrench (like trying to tighten up scope rings without the scope pissing off out of level). You as the user really define the accuracy of the torque you achieve on the screw, and things like cleaning and lubrication of the threads, amount of downward pressure and rate of turning of the wrench, angle off, driver type and size, stretch in the screws and parts all combine to create error. For the average firearms application actual torque is less important that achieving the same torque every time within a suitable range (start the argument now haha).

Couldn’t agree more. Using a torque wrench is as much about technique as it is accuracy of applied force. You are looking for a tension limit but more importantly consistency is key.
Nice bit of kit though, also interested in your experiences with it as it’s on my hit list for future purchase.
