Description
This page lists the Snap-on TESI10 Torqometer under its plain code, the way Lost in HCM names it: “Newton Meter Basic – TESI10”. No chart or certificate appears in that name. If your quality file needs a certificate on delivery, see the TESI10C version with a calibration certificate. Snap-on prints one catalog row for this wrench, so the dial itself does not change.

TESI10 or TESI10C: a paperwork decision
Snap-on’s Newton Meter table carries a short note. Wrenches in the chart ship without a certificate of calibration, while a C at the end of the stock number orders one. So the TESI10 and the TESI10C share the 1/4 inch drive, the scale and the body. Only the document in the box differs.
Matching the Snap-on TESI10 Torqometer to your situation
| Your situation | Better code |
|---|---|
| A supplier audit is due next month, and the tool must show a record from day one | TESI10C |
| Receiving holds any gauge that arrives without a document | TESI10C |
| Your own torque tester verifies every new tool before release | TESI10 |
| A contracted lab checks new tools on arrival anyway | TESI10 |
| A spare wrench for a training bench on a tight budget | TESI10 |
In short, the plain code saves money whenever another record will exist before first use. However, if nobody can check the Snap-on TESI10 Torqometer before it reaches an audited station, the certified code closes that gap.
The shared TESI10 catalog row, line by line
- Drive: a 1/4 inch square.
- Scale: 10 N·m, marked in 0.5 N·m steps.
- Body: 9-29/32 in long and 2-11/16 in wide.
- Head depth: 1-1/4 in, not counting the square drive.
- Storage case: PB9.
- Indicator: Basic, so one needle shows the torque achieved.
The row sits in the Newton Meter Reading/Standard 2% Accuracy table on page 334 of CAT1500i. Next to it, Snap-on lists the TESI10FU follow-up and the TESI10L signal model.
Getting good readings from the Snap-on TESI10 Torqometer
Snap-on’s UK brochure advises caution below 20% of full scale, because readings there may not be accurate. On a 10 N·m dial, 20% equals 2 N·m, so keep your targets above that. The brochure also suggests a wrench whose working range falls near the middle of its capacity. Also, pull smoothly and read the needle with your eye square to the dial. Finally, respect the rated torque, and keep the TESI10 away from seized fasteners.
Putting the TESI10 on a purchase request
Lost in HCM supplies Snap-on dial wrenches in Vietnam and prepares every quote. Write TESI10 on your request for the plain version, or TESI10C for the certificate version. After that, send Lost in HCM a quote request. You can also compare other sizes in our torque wrench range, or contact SMK Vietnam for help with the choice.
Plain versus certified: TESI10 FAQ
Will the TESI10 read differently from the TESI10C?
No. Snap-on prints a single row for both, so the scale, the steps and the drive match.
Can we add a certificate later?
Snap-on’s route is the C code at the time of order. After delivery, your own lab or an outside lab can check the wrench and issue its own report.
Does periodic recalibration still apply?
Yes. Snap-on states that periodic recalibration keeps a dial wrench accurate, whichever code you buy.
