Description
Here you see the Snap-on TESI20 Torqometer in its plain form. Lost in HCM’s listing reads “Newton Meter Basic – TESI20” and mentions no certificate. When a certificate must arrive with the tool, the right page is the certified TESI20C dial wrench. Otherwise the two match, from the 3/8 inch drive to the 20 N·m dial.

Five questions that pick the code
- Does your quality manual ask for a certificate before a gauge enters service? If yes, order the TESI20C.
- Is an audit due before you could book a lab check? Then the C code avoids a gap in the record.
- Do you own a torque tester that covers 20 N·m? If so, the TESI20 lets you verify it in-house.
- Will an outside lab check every new tool anyway? In that case, a factory certificate adds little.
- Is the wrench a spare for training or rework? Then the plain code usually fits the budget.
Snap-on supports this choice directly. Its catalog notes that wrenches in the Newton Meter chart ship without a certificate, and that adding C to the stock number orders one.
What stays the same on the Snap-on TESI20 Torqometer
| Item | CAT1500i value |
|---|---|
| Square drive | 3/8 in |
| Range / increments | 20 N·m / 0.5 N·m |
| Length / width | 9-29/32 in / 2-11/16 in |
| Head depth (drive excluded) | 1-1/4 in |
| Storage case | PB9 |
| Indicator | Basic, one needle |
Because the row is shared, a TESI20 and a TESI20C read alike on the bench. Also, the same row offers the TESI20FU with two needles and the TESI20L with a signal light.
In-house verification with the TESI20
If you buy the plain code, verify it before first use. First, check that the needle rests on zero. Next, load the wrench at a few points across the useful part of the scale on your tester. After that, log the readings against the asset number. Snap-on’s UK brochure flags readings below 20% of full scale, so start your checks at 4 N·m or above. Snap-on also states that periodic recalibration is necessary, so add the TESI20 to your recall list.
