Description
Medical device plants in Vietnam assemble catheters, pumps, meters and surgical handpieces for export. Their work instructions often list screw torque in ounce-inches or pound-inches, taken from U.S. design data. The Snap-on TQS050A torque driver reads those values straight off a U.S. basic dial, up to 96 in-oz. With a 7-3/4 inch body, it sits comfortably on an assembly bench.
Why a 6 in-lb dial fits device assembly
Plastic housings, thin metal brackets and fine threads share one weak point: they strip long before a person feels resistance. A 6 in-lb scale puts those joints in the middle of the dial. Moreover, the 2 in-oz graduations let an operator see small changes as the screw seats. As a result, a line can confirm torque without guesswork.
TQS050A key figures
| Parameter | U.S. units | Metric (calculated) |
|---|---|---|
| Full scale | 96 in-oz / 6 in-lb | about 68 N·cm |
| Graduation | 2 in-oz / 1/8 in-lb | about 1.4 N·cm |
| 2% band start (20%) | 1.2 in-lb | about 14 N·cm |
| Length | 7-3/4 in | about 197 mm |
Snap-on ships the driver in a PB47 storage case. In addition, the basic model has one needle, so it shows torque only while you turn.
A QA bench routine with the Snap-on TQS050A torque driver
- Confirm the target and unit on the current work instruction.
- Check that the needle rests on zero before the first screw.
- Seat the bit, then turn slowly and stop at the value.
- Record the reading by hand, since the basic dial does not hold it.
- Wipe the tool and return it to the PB47 case at the end of the shift.
For audits that need a held peak, consider the follow-up TQS050FUA instead.
Standard TQS050A or stubby TQSS050A?
Both read the same 96 in-oz scale. However, the stubby TQSS050A is 5-1/4 inches long for deep housings. The standard TQS050A gives a fuller grip and a steadier hand on open benches, which most device lines have. Therefore it is often the first choice for a fixed station.
Medical device line FAQ
Does the Snap-on TQS050A torque driver read both clockwise and counterclockwise?
Yes. Snap-on states its Torqometer accuracy for both directions, which also covers left-hand threads.
Which size comes next if our value is above 6 in-lb?
The TQS1A doubles the scale to 12 in-lb with 1/4 in-lb steps.
Can SMK Vietnam calibrate the TQS050A?
No. SMK Vietnam lists the product only, so arrange checks with a calibration lab of your choice.
