Size: 2.5-11.5"/lbs Variable Torque Adjustment Range Verified Purchase
This is a wonderful tool. So well designed. Bits are easy to put in/out, and when it's "in", it cannot be removed without a simple & easy push of the collet. When torque is reached, the feel and "click" is very noticeable; it seems impossible to over-torque. The only weakness is that it's not 100% clear which torque setting is currently selected. For example, when I think I've set it for 3 inch-pounds, it might really be 3.5. I sent a request for clarification to the manufacturer but haven't received a reply, yet (5 days).

Size: 2.5-11.5"/lbs Pre-Set Adjustable Torque Range Verified Purchase
Expensive, but incredibly nice. Dial in your desired torque limit and you're all set. The Wera handle is very comfortable, easy to grip, and turns smoothly in the collar bearing. It's worth getting the Wera bits to go with it--they just don't slip. Look for sets that come with both Philips and Pozidrive. The difference is subtle but performance is dramatically improved with the right bit.

Be careful to read the specifications for the driver and get the right one for your application. Wera makes several adjustable range drivers and many fixed torque drivers...they all look the same in pictures.

I purchased this torque driver to double-torque the DC breakers in my solar system. The manufacturer recommended torquing once, waiting and hour, then torquing again (to prevent copper cold flow). This driver fits comfortable in your hand. It has a very solid click when you reach the set torque rating. The 7446 has a torque range with 22 in-lbs near the middle of the adjustable torque range. The driver head holds the bits firmly in place; I never had one slip out. A friend who works in QA said most local calibration places will calibrate these for a cheap fee.

The description of the item could be better. I'm sure it is a precision device, but it did not meet my needs. There is no direct read between the torque you select in that there no scale. You take the cover off of the end of the handle and turn the screw x number of times for x inlbs of increase in torque. I prefer a direct read.

I'm giving it 2 stars only because it works but this is a very poorly designed product.

Cons:
- The adjustment screw is located underneath a cap that is REALLY difficult to remove. If this is an adjustable tool, I shouldn't need to pry the cap off every time. There is no insertion hole to help either. So you end up damaging the cap while inserting something to pry if off. Better take if off once and never replace it but you'll have a permanent hole at the end of your brand new screw driver.

- The description clearly states that "Torque can easily be set to the required scale value by hand without special tools". THIS IS A LIE! You need an hex driver long enough to reach the adjustment screw and thin enough to pass through the end access port (that is, if you were able to remove the impossible cap in the first place)

- When adjusting the torque, tightening the adjustment screw, it goes deeper down the handle (toward the front of the driver). There doesn't seem to be a limit to this travel so you can end up with a screw that is too deep for your hex driver to reach. That means that you may end up with an adjustable driver that is simply not adjustable anymore. At least not without some special tools to be able to reach such a recessed screw.

- Oh, have I mentioned that while the hex screw travels downward, there's an axis that keeps you from getting to it? I know... this is unbelievable but it's the sad truth.

I'm gonna post a few photos of what I'm saying tonight so it's clearer.

One thing about buying quality tools.....you'll never regret it.
Superb design ,ease of use . Everything I have come to expect from Wera.
Was it cheap? NO! Quality never is.
If you're on the fence about spending this kind of money on a tool---buy it.
You'll thank yourself every time you use it.

Needed for tightening small screws to a specified torque. The torque calibration was accurate, the tool comfortable, and the price very reasonable. Delivery was as promised.
