Description
The Snap-on TER12A Torqometer is the plain “US/ New. Met. Basic – TER12A” code, a 3/8 inch dial wrench with newton meter and inch-pound scales. Lost in HCM also offers the TER12AC with Calibration Certificate, the same wrench with that document added. This page explains which of the two belongs on your order.
TER12A versus TER12AC: one row, two codes
Snap-on prints the TER12A in the Precise 1% Accuracy table of its CAT1500i catalog. The note under that table says the wrenches listed there come without a certificate of calibration. It adds that a C at the end of the stock number orders one. So the TER12AC carries the certificate, while the TER12A leaves the first record to you.
Matching the code to your situation
| Situation | Code to order |
|---|---|
| Your lab tests each new wrench before release | TER12A |
| Customer audit within weeks, no lab slot free | TER12AC |
| Spare for a bench that holds a checked master | TER12A |
| Receiving rule: no gauge without a document | TER12AC |
In short, the plain Snap-on TER12A Torqometer saves money when your own system creates the record. However, it adds work if nobody can test the wrench soon.
Battery pack lines and the Snap-on TER12A Torqometer
Vietnam now builds electric scooters and the battery packs inside them. Those lines fit busbars, terminal screws and module brackets with small, tight values. Many of those specs arrive in N·m, which the TER12A reads directly. Also, a quality engineer can audit a sample of joints and log the real number. With one needle on a Basic dial, take the reading before you ease off.

Snap-on’s UK brochure says readings under 20% of full scale may not be accurate. So keep busbar targets above 3.4 N·m on the Snap-on TER12A Torqometer, or move to a 1/4 inch size. In addition, stay within rated torque, and never use the wrench to loosen a joint.

TER12A questions from battery lines
Is the TER12A less accurate than the TER12AC?
No. Both codes share one catalog row and one accuracy table. The documents are the only difference.
Which size suits screws under 3 N·m?
The TER6A on a 1/4 inch drive reads to 8.4 N·m, so it covers lighter joints.
Can we get a peak-hold version of the TER12A?
Yes. Snap-on lists the TER12FUA, which adds a second needle that keeps the reached value.
