Snap-on TQS4AC Torque Driver, U.S. Basic Dial with Chart, 50 in-lb, 1/4″ Square Drive in Handle

Description

The Snap-on TQS4AC torque driver is the code that Lost in HCM titles U.S. Basic Torque Driver “with Chart”. You can also buy the plain TQS4A without the chart, which shares the same 50 in-lb dial. So pick this code when a document must travel with the tool, and the plain one when it need not.

Chart listing versus the plain TQS4A

Snap-on lists the TQS4A in the 1/4 inch US Reading driver table of catalog CAT1500i. A note there says the codes in the table come without a certificate of calibration. Adding a C to the stock number orders the version with one. Therefore the TQS4AC lines up with that C rule, while the partner title speaks of a chart. Neither source spells out its contents.

A receiving dock story

Picture an appliance plant that has just won a new export contract. Its customer audits incoming gauges, and every torque tool needs a record before the line opens. Here the Snap-on TQS4AC torque driver fits well, because the paper comes in the box. As a result, goods-in can tag the driver and pass it to the line the same week.

The in-house lab story

Now picture a plant with its own torque tester and a technician who logs each new tool. That site checks a 50 in-lb driver itself and writes its own record. So the plain TQS4A does the same job for less than the TQS4AC, and the savings can buy bits or a stubby TQSS4A.

Snap-on TQS4AC torque driver at a glance

• Range of 50 in-lb, marked in 1 in-lb steps.
• Standard body, 8-11/16 in long.
• Basic dial with one needle that shows torque as you turn.
• A 1/4 in internal square drive in the handle, per the catalog footnote.
• PB47 storage case.

All of these figures come from the TQS4A row on page 336 of CAT1500i, since the TQS4AC shares it.

What the internal square drive adds to the TQS4AC

Snap-on marks the TQS4A with a footnote: it includes a 1/4 inch internal square drive in the handle. So the TQS4AC can work with 1/4 inch square-drive accessories. In practice, that lets one dial reach more than one style of fastener on an assembly. Also, keep the work below the 50 in-lb top, since Snap-on tells users not to exceed rated torque.

Purchase-stage questions about the TQS4AC

Is the TQS4AC dial the same as on the TQS4A?

Yes. Snap-on prints a single row for the standard 50 in-lb basic driver, so the TQS4AC scale and length match.

Is there a follow-up version with a chart?

Lost in HCM lists the TQS4FUAC. Unlike the TQS4AC, it adds a second needle that holds the peak.

Will the TQS4AC need rechecks later?

Yes. Snap-on states that periodic recalibration keeps accuracy, so set a TQS4AC interval in your tool plan.
