Snap-on TQS1FUAC Torque Driver, Torqometer U.S. Follow-up Dial, 12 in-lb, 7-3/4″ Body, with Chart

Description

Medical device plants in Vietnam assemble patient monitors, pumps and handheld scanners for export. Also, their housings close with small screws. Each one needs a known torque, so the case seals and the parts stay aligned. The Snap-on TQS1FUAC torque driver gives quality teams that number on a dial. It is a full-length Torqometer driver with a U.S. scale and a follow-up needle, and Lost in HCM lists it with a chart.

Device housings and the Snap-on TQS1FUAC torque driver

A device maker sets the screw value during design, then checks it on every build lot. For example, a QA inspector might audit five housings per lot against the drawing. With the follow-up needle, the peak stays on the dial after the turn. So the inspector reads it with the driver clear of the part and logs it in the lot record. That flow suits plants that work under strict quality systems.

Specs Snap-on prints for the TQS1FUA

These figures sit in the U.S. driver table of Snap-on catalog CAT1500i. According to that table, a C added to the stock number orders a certificate of calibration. So the TQS1FUAC is the C version of the TQS1FUA. Lost in HCM calls it the chart version, so confirm what papers ship with it.

How fine are the TQS1FUAC steps?

First, each mark on this dial equals 1/4 in-lb, or 4 in-oz. That is about 0.03 N·m, so small changes show up clearly. Snap-on’s standard grade holds within 2% of reading from 20% of full scale upward. Therefore the useful band runs from 2.4 in-lb to 12 in-lb, about 0.27 to 1.36 N·m. For lighter screws, the TQS050FUA tops out at 6 in-lb. Meanwhile, the TQS2FUA reaches 24 in-lb.

TQS1FUAC or the stubby TQSS1FUA?

The TQS1FUAC has a 7-3/4 inch body, which gives a steady grip on an open bench. By contrast, the TQSS1FUA stubby shares the range in a 5-1/4 inch body. Therefore choose the stubby when the screw sits deep inside a frame or close to a wall.

Clean bench habits with the TQS1FUAC

• Wipe the handle with a dry cloth, and follow your area rules for any solvent.
• Zero the follow-up needle before each screw.
• Use the bit type on the drawing, and replace it when the tip rounds.
• Return the Snap-on TQS1FUAC torque driver to its PB47 case after each lot.

Device QA FAQ

Does the TQS1FUAC read in metric units?

No, Snap-on lists its range in in-oz and in-lb. Multiply in-lb by about 0.113 to get N·m.

Is the driver suitable for cleanrooms?

The listing makes no cleanroom claim. Check it against your own area rules before use.

Why choose a dial over a preset driver for audits?

A dial shows the value you reached, not only a pass. So it can catch a drifting line tool before parts fail.
