Description
Eight inch-ounces is only half an inch-pound. The Snap-on TQSS004FUAC torque driver works at that delicate level. It is a Torqometer stubby driver with a US scale, a follow-up dial and, according to its name, a chart.
Measuring tiny torque with the Snap-on TQSS004FUAC torque driver
Many torque screwdrivers only stop at a setting. This one shows a reading on a dial instead. So a technician can see how much torque a small screw actually took. The follow-up pointer then holds the peak value, and the reading stays visible after the turn ends.
Why the stubby body helps
A short body fits inside cramped housings and close to panels. It also keeps the hand near the screw, which gives better control at very low torque. For example, it suits work inside an instrument case or behind a small bracket.
Converting 8 in-oz
One in-oz equals about 0.706 N·cm. Therefore 8 in-oz is roughly 5.6 N·cm, or 0.056 N·m. The name rates the TQSS004FUAC at 8 in-oz, while Lost in HCM can confirm the low end of the dial and its divisions. Choose it only when your spec sits inside that small band.
Jobs that suit a dial torque driver
- Checking the torque that small screws in meters and relays took.
- Measuring the turning torque of trimmers, small knobs and adjusters.
- Audit checks on screws in optics, watches and sensors.
- Comparing assembly methods during a process trial.
In each case, the operator wants a number rather than a simple stop. That is why the TQSS004FUAC earns a place on the QA bench.
Drive and bits
The supplier lists the TQSS004FUAC among its 1/4-inch drive Torqometer torque drivers. So plan the bit holder or adapter that links the drive to your screw. Also use fresh bits, since a worn tip can slip and spoil a reading at such low torque.
Care tips
Store the driver in its case, away from shock and dust. In addition, return the pointer to zero before each check. Then have the TQSS004FUAC calibrated on your plant’s cycle, because small instruments drift too.

It has a pointer that stays at the highest reading. So you can read the peak after you lift the driver off the screw.
How much is 8 in-oz in metric units?
It is about 5.6 N·cm, which is roughly half an inch-pound.
Does it read in metric units?
The name lists a US reading. Ask Lost in HCM about other models if your specs use N·cm.
