Description
Motorcycle and scooter plants in Vietnam assemble handlebar switches, headlamps, tail lamps and meter clusters at high volume. Those parts use small screws in plastic shells, and many Japanese service sheets state torque in kgf·cm. The Snap-on TQSC2.5FUAC torque driver reads kg·cm and in-lb on one face, so an inspector can check either unit directly. A follow-up needle also holds the peak after each turn.
Switches, lamps and meters with the Snap-on TQSC2.5FUAC torque driver
A switch housing that sits too loose rattles, while one that sits too tight cracks at the boss. So line quality teams pull bikes from the end of the line and check a sample of these screws. With the TQSC2.5FUAC, the inspector turns until the screw just moves on, then reads the held needle. That value then goes onto the audit sheet next to the frame number.
TQSC2.5FUA in the U.S./metric driver chart
| Item | TQSC2.5FUA |
|---|---|
| Model type | Standard follow-up (2 needles) |
| Length | 7-3/4 in |
| Range | 35 kg·cm / 30 in-lb |
| Increments | 1 kg·cm / 1 in-lb |
| Stubby twin | TQSSC2.5FUA, 5-1/4 in |
| Case | PB47 storage case |
These numbers appear in the Combination US/Metric driver chart of Snap-on catalog CAT1500i, and the 2005 Torqometer notice agrees. Per the catalog, the chart models carry no certificate, while a trailing C orders the certificate version. The TQSC2.5FUAC therefore matches the TQSC2.5FUA plus that C. Since the listing title also says it comes with a chart, confirm the paperwork with Lost in HCM.
Two scales, one reading on the TQSC2.5FUAC
Snap-on guarantees this grade within 2% of reading from 20% of full scale to the top. For this dial, the band opens at 7 kg·cm, or 6 in-lb. The full scale of 30 in-lb equals about 3.4 N·m. To turn kg·cm into N·m, multiply by about 0.098. For example, a 20 kg·cm target works out to about 2 N·m.
Line-side habits for the Snap-on TQSC2.5FUAC torque driver
- Clear the follow-up needle before every screw in the sample.
- Keep the bit square, because a tilted tip cams out of small cross-head screws.
- Write the unit beside each value, since two scales invite mix-ups.
- Store the driver in its PB47 case away from paint and grease.
In addition, plan a calibration date for the TQSC2.5FUAC just as you would for any gauge.

TQSC2.5FUAC motorcycle plant FAQ
Can the TQSC2.5FUAC audit screws that a power driver ran?
Yes. Turn slowly until the screw just starts to move, then read the held needle. Use the audit method your plant has approved for these checks.
Is kg·cm the same as kgf·cm?
Yes. Both mean kilogram-force centimeter. One kg·cm equals about 0.098 N·m, or about 0.87 in-lb.
Should I pick the full-length or the stubby version?
The TQSC2.5FUAC gives a 7-3/4 inch grip for open benches. For tight spots inside lamp or meter housings, Snap-on lists the 5-1/4 inch TQSSC2.5FUA with the same range.
