Description
Some fasteners need so little torque that inch-pounds are too coarse a unit. The Snap-on QC1ETT10 torque tester works in inch-ounces instead. It reads 10 to 100 in-oz, or 7.0 to 70.6 cN·m, through a 1/4-inch drive, so it suits the lightest tools on a precision line.
Why inch-ounces matter
One inch-pound equals 16 inch-ounces. So a scale in in-oz gives far finer steps for tiny screws in phones, cameras, watches and optical parts. When a driver over-tightens a micro screw, the thread or the plastic boss fails first. A tester at this level shows the error before it reaches a product.
Features from the Snap-on brochure
- Accuracy better than ±1% of the indicated value, from 10% to 100% of the transducer range.
- Track and Peak modes, plus auto or manual display reset.
- Reads in both directions, clockwise and counterclockwise.
- Dual scale display, with an English unit and a metric unit.
- Integral transducer and sturdy housing that mounts in almost any position.
In addition, Snap-on shaped the neck so the operator can still see the display while testing a long tool.
Where the Snap-on QC1ETT10 torque tester fits
Electronics plants use it at the start of a shift to check preset and adjustable torque screwdrivers. Likewise, medical and optical device makers use this class of tester for their audit trail. R&D labs also find it handy when they set a new torque spec for a prototype.
Checking screwdrivers
Fit the driver to the 1/4-inch drive with a suitable bit adapter. Then turn it slowly until it slips or clicks, and read the peak value. Repeat a few times, because a single reading hides scatter. Finally, log each tool against its ID so you can trace any drift.
Care and recalibration
Keep the tester on a stable bench or wall bracket, away from vibration and air guns. Also wipe off dust before each shift. Snap-on notes that every torque tool needs periodic recalibration, and that rule covers the tester too. So plan a yearly check with an independent lab.

QC1ETT10 questions
What range does the QC1ETT10 cover?
It covers 10-100 in-oz, which is 7.0-70.6 cN·m, through a 1/4-inch drive.
Can it test power screwdrivers?
Snap-on says these testers work with non-impacting power tools, but a joint rate simulator is required. Ask Lost in HCM which simulator suits your tool.
Which tester do I need for higher values?
Pick a model with an in-lb range, such as another tester from the same Snap-on series.
