Description
This page covers the Snap-on TER3A Torqometer under its plain catalog code, which Lost in HCM lists as “U.S./ New. Met. Basic – TER3A”. No suffix follows the number, and that detail matters. If your quality file needs a document on arrival, see the TER3AC listing with a calibration certificate. Otherwise, the plain code may be all you need.
What the bare TER3A code tells a buyer
Snap-on’s CAT1500i catalog adds a short note under its Torqometer tables. It says the wrenches in the chart come without a certificate of calibration. A buyer who wants one adds a C to the stock number. So the TER3A and the TER3AC share one row, one dial and one 1/4 inch drive. Only the paperwork sets them apart.
Where the Snap-on TER3A Torqometer fits best
Picture a plant that already owns a small torque tester and a trained metrology tech. That team checks every new gauge before release, then writes its own record. For them, a factory document repeats a step. The plain code also works well as a spare, because staff can compare it with a certified master on site.
- Your lab verifies each new tool before it reaches the line.
- A contract lab already tests your torque tools on a fixed cycle.
- The wrench will serve training or rework, not final sign-off.
- Budget is tight, and you would rather spend it on bits and sockets.
Cases that point to the TER3AC
Some customers audit suppliers and expect a record for each measuring tool from day one. Likewise, a receiving desk may hold any gauge that lacks a document. In those cases, the certificate code spares you a wait for outside testing before first use.
Catalog row behind the TER3A dial
| Feature | TER3A figure |
|---|---|
| Drive size | 1/4 in |
| N·m dial | 3.5 N·m, marked every 0.1 N·m |
| in-lb dial | 30 in-lb, marked every 1 in-lb |
| Overall length | 9-29/32 in |
| Body width | 2-11/16 in |
| Head depth, drive excluded | 1-1/4 in |
| Case code | PB9 |
The TER3A is a Basic model, so one needle tracks the torque you reach. Snap-on places it in the Combination US/Newton Meter Reading/Precise 1% Accuracy table. In addition, that row offers the TER3FUA follow-up and the TER3LA signal versions.
Small scale, careful habits with the TER3A
A 3.5 N·m dial rewards a light, even pull. Snap-on’s UK torque brochure warns buyers about wrenches scaled below 20% of full scale. It also advises a size where the working range sits near the middle. Therefore aim most TER3A jobs well up the dial. Also respect the rated torque, and keep the wrench off seized screws.
Buying a plain Snap-on TER3A Torqometer
Factories in Vietnam order Snap-on dial wrenches through Lost in HCM, which handles every quote. Write TER3A with no suffix on your request, so the plain code ships. When the spec is clear, send your TER3A request to Lost in HCM. For other ranges, our torque wrench range helps, and you can contact SMK Vietnam about sizes.
TER3A questions before you buy
What if an auditor later asks for a TER3A record?
Your in-house lab or a contract lab can test the wrench and write its report. However, a Snap-on certificate in the box comes only with the TER3AC code.
Does the plain code read any differently?
No. CAT1500i gives both codes one row, so the dial, scales and drive match.
How often should we recheck the TER3A?
Snap-on says periodic recalibration keeps a Torqometer accurate. So set the cycle in your quality plan, and shorten it for wrenches in heavy daily use.
