Description
A tool crib that issues dozens of 3/8-inch wrenches needs a fast, fair way to check them on return. The Snap-on QC2ETT1000 torque tester fills that role. It covers 100 to 1000 in-lb, or 113 to 1,130 dN·m, and accepts tools through a 3/8-inch drive.

Built for the busy crib
Snap-on made its ETT testers sturdy and simple, so anyone on the team can use them. You mount the unit, fit the wrench and pull to the click. Then the display holds the peak value until you reset it. As a result, each tool check stays quick and consistent.
Specs that matter
- Accuracy better than ±1% of the indicated value, across 10-100% of the range.
- Reads in both directions, which helps with left-hand thread tools.
- Track and Peak modes, with auto or manual reset.
- English and metric scale on the same display.
- Neck design that keeps the display in sight with long wrenches.
Where the Snap-on QC2ETT1000 torque tester works best
Machine shops use this range for fixtures, couplings and motor mounts. Similarly, engine and compressor assembly lines rely on 3/8-inch wrenches in the upper inch-pound band. Maintenance teams in plastics, packaging and food plants also check their wrenches here before a planned shutdown.
Reading the accuracy spec
The ±1% figure applies from 10% to 100% of the transducer range. In other words, tests from about 100 in-lb upward fall inside the rated band. Still, aim for test points well above the bottom of the scale, because that is where the reading is most useful.
Keeping it reliable
Bolt the tester to a rigid wall or bench, since flex adds error. Also keep the square drive clean and check it for wear now and then. Most important, have the tester itself recalibrated at regular intervals by an independent lab.

Will it test counterclockwise wrenches?
Yes. The ETT series reads both clockwise and counterclockwise.
Can I mount it on a wall?
Yes. Snap-on designed the series for wall or bench mounting near the work area.
