Description
Japanese and Korean drawings often give screw torque in kgf·cm, while US parts lists use inch-pounds. The Snap-on TQSSC2.5FUAC torque driver reads both on one dial. It is a short Torqometer dial driver, and Lost in HCM lists it with a chart. So it suits electronics and appliance plants in Vietnam that build to specs from several countries.
Two scales on the Snap-on TQSSC2.5FUAC torque driver
Snap-on’s industrial catalog lists the TQSSC2.5FUA at 35 kg·cm / 30 in-lb full scale. The dial steps are 1 kg·cm and 1 in-lb. As a result, an inspector can read a kgf·cm spec straight off the face. However, the metric side shows kilogram-force centimeters, not newton meters. If a drawing gives N·m, convert it first, because full scale works out close to 3.4 N·m.
Why a stubby body helps in tight housings
The same catalog page gives the TQSSC2.5FUA stubby a length of 5-1/4 inches. The shorter body slips between PCB stand-offs, into meter cases and behind small brackets. It also keeps your hand near the screw, so side load stays low. Lost in HCM files it with its 1/4-inch drive Torqometer drivers, so plan the bit holder you will use.
Research logs and screw audits with the TQSSC2.5FUAC
- Log the peak torque each screw took during a joint trial on a new plastic boss.
- Audit screws that automatic drivers ran on the line, one sample per hour.
- Compare thread-forming and machine screws before a design freeze.
Snap-on’s table places this code in its stubby follow-up group, which means two needles. One needle moves with the load, while the follow-up needle stays at the highest value. Therefore the engineer can lift the driver and write the number down calmly, then reset it for the next screw.
Accuracy band of the Snap-on TQSSC2.5FUAC torque driver
Lost in HCM lists this driver under Combination US/Metric Reading/Standard 2% Accuracy. Snap-on’s Torqometer tables define that grade as within 2% of reading, from 20% of full scale to full scale, in both directions. On a 30 in-lb dial, the band starts at about 6 in-lb. So pick this size when your targets sit between roughly 6 and 30 in-lb.
Keeping a small dial driver honest
Zero both needles on the Snap-on TQSSC2.5FUAC torque driver before each session, since one stray reading spoils a log. Keep it in the PB47 case that Snap-on lists with this driver. Also replace worn bits early, because a slipping tip gives a false peak. Snap-on’s catalog adds that a C at the end of a stock number marks the version sold with a certificate of calibration. Lost in HCM names this one with Chart, so ask which paperwork comes in the box.

TQSSC2.5FUAC questions from the QA bench
Does the metric scale read in newton meters?
No. It reads kilogram-force centimeters. Multiply a kg·cm value by about 0.098 to get N·m.
How does the stubby differ from the TQSC2.5FUA?
Snap-on lists the same 30 in-lb / 35 kg·cm range for both. However, the stubby is 5-1/4 inches long, while the standard driver is 7-3/4 inches.
Why does the listing say Basic if it has a follow-up needle?
The title says Basic, but Snap-on’s table lists this code as a stubby follow-up model. So confirm the dial with Lost in HCM.
