Description
Electricity meter plants in Vietnam build thousands of smart meters each shift. Inside each case, small screws hold the circuit board, the display and the cover. If those screws run too tight, a plastic boss can crack and spoil the case seal. The Snap-on TQSSI.70FUA torque driver gives meter engineers a clear newton-meter reading for that work. It is a stubby Torqometer driver with a follow-up needle that keeps the peak.
Meter assembly checks with the Snap-on TQSSI.70FUA torque driver
- Board screws that hold the metering PCB to the base.
- Display and optical port fixings near the front window.
- Cover screws that press on the case gasket.
- Spot checks on automatic screw feeders at line start.
For each one, the inspector drives the screw, lifts the driver away and reads the second needle. So the value waits on the dial while the inspector types it into the batch record.
What CAT1500i lists for the TQSSI.70FUA
Snap-on’s US/Newton Meter driver table puts this model in the stubby follow-up column. It reads to 0.70 N·m in 0.02 N·m steps, while its body is 5-1/4 inches long. In addition, the table says each driver in it comes with a PB47 storage case. Lost in HCM groups the TQSSI.70FUA with its 1/4-inch drive Torqometer drivers.
Sizing the TQSSI.70FUA for meter screws
Snap-on holds its standard grade within 2% of reading from 20% of full scale to full scale. For this size, that band opens at 0.14 N·m and runs to 0.70 N·m, or about 6.2 in-lb. Therefore it suits light board and display screws. For heavier cover screws, the TQSSI1.35FUA reaches 1.35 N·m. Meanwhile, lighter jobs may suit the TQSSI.11FUA at 0.110 N·m. The same table also notes that Precise 1% models are a special order.
No certificate in the TQSSI.70FUA base code
This stock number ends in FUA, without a C. Snap-on’s table says the drivers in it do not include a certificate of calibration. Instead, you add a C to the stock number to order one. So if your meter customer wants a certificate on arrival, ask Lost in HCM whether the C version is available. Otherwise, your own calibration provider can certify the TQSSI.70FUA after delivery.
Line care for the TQSSI.70FUA
Zero the follow-up needle before every screw, and hold the driver upright. Also follow your plant’s ESD rules, because the source does not describe the handle material. Swap worn bits early, since a slipping bit spoils the peak. Then return the Snap-on TQSSI.70FUA torque driver to its case at the end of the shift.

Smart meter line FAQ
Does the TQSSI.70FUA show inch-pounds as well?
Lost in HCM calls it a US/newton meter driver. However, the Snap-on row we checked prints only N·m, so confirm the second scale in your quote.
Can it check the meter terminal screws?
Only if the terminal value sits at or below 0.70 N·m. Many terminal screws need more, so check the drawing before you pick this size.
Is a 1% version available?
Snap-on’s table says Precise 1% models come on special order. Ask Lost in HCM whether they can source one for this size.
