Description
The Snap-on TESI70FU dial wrench on this page is the plain code, listed by Lost in HCM without certificate wording. If you need that paperwork, see the TESI70FUC with Calibration Certificate instead. Otherwise, the two codes buy you the same 3/8 inch follow-up dial.
Side by side: TESI70FU and TESI70FUC
| Item | TESI70FU (this page) | TESI70FUC |
|---|---|---|
| Certificate of calibration | Not included, per the CAT1500i table note | Included, per its listing name |
| Square drive | 3/8 in | 3/8 in |
| Range / increments | 70 N·m / 2 N·m | Same row |
| Length | 12-1/2 in | Same row |
| Needles | Two (Follow-up) | Two (Follow-up) |
| Storage case | PB9 | Same row |
Snap-on prints only the base row, and its note says a C on the stock number orders the certificate model. So the comparison changes in one line only.
Situations that favor the Snap-on TESI70FU dial wrench
- Your torque lab verifies every new tool before release anyway.
- A contract lab picks up new gauges on a fixed weekly run.
- You need a backup wrench for a bench that rarely faces audits.
- Budget is tight, and the saving buys the adaptors you also need.
Situations that favor the C code
- Supplier audits require a record from the first day of use.
- Your receiving team quarantines any gauge without a document.
- A line launch leaves no window for a lab trip.
Neighbors in the 3/8 inch row
The TESI70FU shares its 12-1/2 inch body with the TESI60FU and the TESI75FU. However, the TESI75FU reads in 1 N·m steps, while the TESI70FU and TESI60FU use 2 N·m steps. So if your targets need finer marks, compare those rows first. For any of them, Snap-on’s UK brochure gives the Standard 2% band from 20% of full scale, which means 14 N·m and up on this dial.
Daily care of the Snap-on TESI70FU dial wrench
Keep the TESI70FU in its PB9 case when it leaves the bench. Before each shift, confirm that both needles sit at zero. Then pull slowly and square to the fastener, so the reading stays steady. Never go past 70 N·m, and never use the wrench to crack a tight bolt. Finally, set a recheck cycle, because Snap-on calls periodic recalibration necessary.

Plain-code TESI70FU questions
Can I turn a TESI70FU into the C code later?
Not as a code change. However, your lab or an outside lab can test the wrench and issue its own report.
What do the two needles on the TESI70FU show?
Snap-on says they show the targeted torque and the torque achieved. So you can read the result against the target.
