Gearwrench Torque Screwdriver Takes the Guesswork out of Setting Small Fasteners
Over-torquing fasteners, at best, risks damaging the fastener. At worst, you get to replace a part that wasn’t part of your cost equation. When it comes to smaller fasteners, Gearwrench aims to take the guesswork out with its torque screwdriver set.

Pros

Cons
- A Newton-meter scale would be nice
Using the Gearwrench Torque Screwdriver
Torque Range and Accuracy
One of the things we love about Gearwrench’s design is the single-digit torque settings from 10 – 50 in-lbs. To set the torque you’re looking for, pull down the release and twist the handle left or right.
The shaft has a “tree” of measurements hitting every 10 in-lbs and a ring below that has measurements from 0 – 9. Let’s say you’re shooting for 25 in-lbs of torque. Twist the handle until it gets to the base of the 20 branch and then keep turning clockwise until you see the 5 on the ring.
The accuracy is ±6%. Compared to some of the tools we use, that sounds like a lot. Even at the very top of the scale, 6% puts you in a range from 47 – 53 in-lbs, and that’s not so bad. On the small end of the range, it’s 9.4 – 10.6 in-lbs.
The only thing we’d like to see is a Newton-meter scale in addition to the in-lbs for parts that spec Nm instead. With the way the shaft and ring measurements work, that’s not practical, so we’ll have to do the math or look it up for now.
Installing Bits
Installing bits is super simple. The torque screwdriver’s collet has a one-hand entry design. Just push the bit in place and the collet secures it. To release the bit, push the collet back up.
The nice thing is that it’s a 1/4-inch hex receiver, so you can use any 1/4-inch hex bit you have on hand if there’s something that’s not in the kit. We found a couple of bits from other brands that we were able to pull out with some effort, but they held more than well enough to work with.
