Description
Drone builders in Vietnam fix motors, arms and gimbal plates with small screws into aluminum and carbon parts. Too little torque lets a motor work loose in flight. On the other hand, too much can crush a carbon plate. The Snap-on TQS2FUAC torque driver lets a technician measure each of those screws on a dial. It is a U.S.-reading Torqometer with a follow-up needle, and Lost in HCM lists it with a chart.
Drone airframes and the Snap-on TQS2FUAC torque driver
A multirotor shakes hard on every flight, so motor screws face constant vibration. Builders often add thread locker and then set each screw to the value on the drawing. With this driver, the second needle stays at the peak after each turn. So the technician can lift the tool, read the dial and log the value against the airframe serial. That record also helps when a customer returns a drone after a hard landing.
Catalog data for the TQS2FUA
| Item | TQS2FUA |
|---|---|
| Model type | Standard follow-up (2 needles) |
| Range | 384 in-oz / 24 in-lb |
| Increments | 8 in-oz / 1/2 in-lb |
| Length | 7-3/4 in |
| Drive group | Torqometer drivers, 1/4 in drive |

Snap-on prints these values in the U.S. driver table of its CAT1500i catalog. The same table notes that a C at the end of a stock number orders the version with a certificate of calibration. Therefore the TQS2FUAC is the C form of the TQS2FUA. Lost in HCM calls it the chart version, so confirm the papers in your quote.
Where the TQS2FUAC range fits a drone
Snap-on rates the standard grade within 2% of reading from 20% of full scale to full scale. On a 24 in-lb dial, that band starts at 4.8 in-lb. As a result, the TQS2FUAC suits screws from there up to 24 in-lb, or about 2.7 N·m. That covers many motor mount and arm clamp screws on mid-size frames. However, tiny camera and flight controller screws may sit below the band. For those, the 12 in-lb TQS1FUA gives finer steps.
Shop habits for the TQS2FUAC
- Zero the follow-up needle before every screw.
- Audit thread-locked screws the same way each time, so readings stay comparable.
- Hold the driver in line with the screw and push only as hard as the bit needs.
- Replace worn hex bits, because cam-out spoils the peak.
Also keep the Snap-on TQS2FUAC torque driver in its PB47 case between builds, and send it for calibration on your shop’s cycle.

Drone bench FAQ
Which bits fit the TQS2FUAC?
Snap-on places it in its 1/4-inch drive driver group. Confirm the bit holder you need with Lost in HCM before you order.
Can the dial show newton meters?
No. Snap-on lists the range in in-oz and in-lb only. Multiply an in-lb value by about 0.113 to get N·m.
Why pick a follow-up model over a basic one?
A basic model has one needle that drops back when you stop. The follow-up adds a second needle that holds the peak, so you can read it after the tool leaves the screw.
