Description
Electronics contract makers in Bac Ninh, Bac Giang and Dong Nai mount boards, connectors and heat sinks with small machine screws. Each screw needs enough clamp to hold, but not so much that it cracks a board or strips a standoff. The Snap-on TQSSI1.35FUA torque driver gives their process teams a clear dial reading in newton meters. It is a stubby Torqometer driver with a follow-up needle that holds the peak.
Board-level jobs for the Snap-on TQSSI1.35FUA torque driver
- PCB mounting screws into metal or plastic standoffs.
- Jack screws on D-sub and other locking connectors.
- Heat sink and power module screws, where clamp affects cooling.
- Checks on screw feeders and smart drivers at line start.
In each case, the operator drives the screw, lifts the tool and reads the second needle. So nobody has to judge the value while the bit is still turning.
Catalog values for the TQSSI1.35FUA
Snap-on’s US/Newton Meter driver table in catalog CAT1500i lists this stubby model with a 1.35 N·m full scale. It reads in 0.05 N·m steps and has a 5-1/4 inch body. In addition, the table says every driver in it comes with a PB47 storage case. Lost in HCM files the tool under its 1/4-inch drive Torqometer group.
Base model, no certificate
This code ends in FUA, not FUAC. Snap-on’s table states that the models in it do not include a certificate of calibration. Instead, buyers add a C to the stock number to order one. Therefore, if your customer audit asks for a certificate on arrival, ask Lost in HCM about the TQSSI1.35FUAC. Otherwise, the base Snap-on TQSSI1.35FUA torque driver can go straight to your own calibration provider.
Choosing this size
Snap-on’s standard grade holds within 2% of reading from 20% of full scale to full scale. For the TQSSI1.35FUA, that window opens at 0.27 N·m. As a result, the tool fits screw targets from there up to 1.35 N·m, or about 12 in-lb. For lighter screws, Snap-on also lists stubby follow-up sizes at 0.70 and 0.110 N·m. Meanwhile, the same table notes that Precise 1% versions are a special order.
ESD and bench practice
Electronics lines often require ESD control at each bench. The source does not describe the handle material, so follow your plant’s ESD rules. Also hold the driver upright, zero the needle before each screw and replace worn bits early. Then store the tool in its case when the shift ends.

EMS line FAQ
Is the TQSSI1.35FUA safe for ESD-sensitive boards?
The listing makes no ESD claim. Ask Lost in HCM, and use your normal grounding steps at the bench.
Can it check a powered screwdriver?
Yes, as a spot check. Drive a screw with the powered tool, then turn it slightly further with the dial driver and note where it moves.
Does the dial also show inch-pounds?
Lost in HCM calls it a US/newton meter driver, but the Snap-on row we checked prints only N·m. Confirm the second scale in your quote.
