Description
This page covers the Snap-on TQS1AC torque driver, which Lost in HCM sells as the U.S. Basic Torque Driver “with Chart”. Mechanically it matches the standard TQS1A basic driver, which we list separately. So the difference sits in the documents, and this guide helps you decide whether they are worth it.
Three questions before you buy the Snap-on TQS1AC torque driver
Answer these before you write the order:
- Does an auditor or customer expect a document for each torque tool from the first day? If yes, the chart code TQS1AC is the natural pick.
- Will goods-in hold a measuring tool that arrives with no papers? Then the chart code avoids a wait.
- Do you own a tester that can verify a 12 in-lb driver? If so, the plain TQS1A may serve you just as well.
Snap-on’s catalog backs this split. Its US Reading driver table notes that the printed codes ship without a certificate of calibration, while a C suffix orders one. Lost in HCM’s title calls the extra item a chart, yet neither source lists what it holds.
Where the plain TQS1A wins
Budget often decides the matter. For example, a plant with a torque analyzer can check a new driver in minutes and file its own record. Similarly, a backup driver in a tool crib rarely needs papers of its own. In both cases, the TQS1A keeps the order lean, and the Snap-on TQS1AC torque driver adds little.
Snap-on TQS1AC torque driver specs from the TQS1A row
| Item | Value (TQS1A row, CAT1500i p.336) |
|---|---|
| Length | 7-3/4 in, standard body |
| Model | Basic, one needle |
| Range | 192 in-oz / 12 in-lb |
| Increments | 4 in-oz / 1/4 in-lb |
| Case | PB47 |
As a rough guide, 12 in-lb equals about 1.36 N·m. So the Snap-on TQS1AC torque driver suits small machine screws in housings, brackets and covers, as long as the drawing value sits in that band.
Neighbours in the 12 in-lb row
Snap-on prints four codes on this row. The stubby TQSS1A brings the same scale on a 5-1/4 inch body. Meanwhile, the TQS1FUA and TQSS1FUA add a second needle that stays at the peak. If the target sits low on the TQS1AC dial, the 6 in-lb TQS050A gives finer steps.

Questions on the TQS1AC listing
Do the TQS1AC and TQS1A read differently?
No. The TQS1AC and TQS1A share one catalog row, so range, steps and length match.
Will the TQS1AC keep a peak reading on the dial?
No. The TQS1AC has a basic dial with a single needle. For a held reading, look at the TQS1FUA instead.
Should the chart set our recheck date?
Your quality plan should set it, based on use. The Snap-on catalog also calls for periodic recalibration of tools like the TQS1AC.
