Description
Repair benches that restore pressure gauges, panel meters and dial indicators deal with screws that barely resist a turn. A movement plate or pointer hub can shift if one screw ends up tighter than its neighbor. The Snap-on TQSSI.11A torque driver gives the technician a live dial for that work, with a full scale of only 0.110 N·m.
What 0.110 N·m means at the bench
The TQSSI.11A full scale equals 11 N·cm, or just under 1 in-lb. Meanwhile, each step on the dial adds 0.005 N·m. So the scale splits a very small load into 22 readable parts. As a result, the tech can bring a row of screws to the same mark instead of trusting finger feel.

Gauge and meter jobs for the Snap-on TQSSI.11A torque driver
- Movement mounting screws inside pressure gauges.
- Dial plate and bezel screws on analog panel meters.
- Small cover screws on dial indicators and test gauges.
Of course, instrument makers set the values. Therefore, check the repair manual and keep this driver for screws that sit in the upper part of its scale.
Basic dial or follow-up?
The basic model shows one needle, which returns as soon as you ease off. So it works when the tech watches the dial on every screw. However, the follow-up version uses two needles, so the reading stays put for logging. Pick the basic TQSSI.11A for steady hands and live reading.
Storing a very light driver
First, keep the TQSSI.11A in its PB47 case and away from cleaning solvents. Also hold it upright on the screw, because side load can skew a reading this small. Snap-on says not to break fasteners loose with these tools or exceed rated torque. Then book periodic recalibration at an outside lab.

Instrument bench FAQ
Does the TQSSI.11A come in a longer body?
No. Instead, the CAT1500i row lists this range only as a 5-1/4 inch stubby, in basic and follow-up versions.
What is 0.110 N·m in inch-ounces?
About 15.6 in-oz. The catalog prints only the N·m figure for this size, so ask Lost in HCM about the US markings on the dial.
Can I order a Precise 1% version?
Snap-on notes that Precise 1% models are available on special order. Lost in HCM can check whether that applies to the TQSSI.11A.
