Description
Eyewear plants in Vietnam assemble metal and acetate frames for export brands, and every hinge holds a screw no bigger than a pin. Too much torque strips the thread or splits the barrel. Too little lets the temple wobble within weeks. The Snap-on TQSSI.11FUA torque driver puts that tiny load on a dial, so a QA tech can see it instead of guessing.
How small is 0.110 N·m?
Snap-on’s driver table gives the TQSSI.11FUA a full scale of 0.110 N·m, read in steps of 0.005 N·m. That equals 11 N·cm, or just under one inch-pound. In other words, two fingers can pass it without any feel of resistance. A measured driver therefore gives the line a fixed reference for each hinge size.

Eyewear jobs for the Snap-on TQSSI.11FUA torque driver
- Hinge screws on metal and acetate temples.
- Nose pad arm screws on wire frames.
- Rimless lens mounting screws, where a hard turn can chip the lens.
- Bench audits of electric screwdrivers set for hinge work.
Watch repair benches also work at a similar scale.
Why two needles help a QA bench
Snap-on describes Follow-up models as having two separate needles. The first marks the targeted torque, while the second tracks the torque achieved. So an inspector can compare both after each screw and log the result. Thus the TQSSI.11FUA suits audits as well as daily production checks.
Grade and working band
Lost in HCM files this driver under Combination US/Newton Meter Reading/Standard 2% Accuracy. Snap-on defines its Standard grade as within 2% of reading, from 20% of full scale to the top. On the TQSSI.11FUA, that band starts at 0.022 N·m. The catalog also notes that Precise 1% versions of these drivers come on special order.
Care at the frame line
First, keep the Snap-on TQSSI.11FUA torque driver in its PB47 case when the shift ends. Then wipe off polish dust and hand oil before storage. Also hold the driver upright on the screw, so side load does not skew the reading. Never use it to free a stuck screw, and send it to an outside lab for periodic recalibration.

Frame line questions about the TQSSI.11FUA
Does the TQSSI.11FUA show inch-pounds?
Snap-on’s row prints only the 0.110 N·m scale. Since that is just under 1 in-lb, ask Lost in HCM about the dial markings before you order.
Is it a click-type driver?
No. The TQSSI.11FUA is a dial driver, so you watch the needles and stop at the value on your drawing.
Can I get a version with a certificate?
Snap-on’s table says a C on the end of the stock number orders one. Lost in HCM can check whether the TQSSI.11FUAC is on offer.
