Description
This page covers the Snap-on TEC50AC dial wrench, which Lost in HCM names a U.S./Metric Basic Torqometer “with Chart”. Its plain twin, the Snap-on TEC50A Basic dial wrench without a chart, has its own page on this site. The dial, drive and scales match. So the decision rests on the documents your site expects.
Reading the C on the end of TEC50AC
Snap-on’s CAT1500i catalog prints the TEC50A in its Combination US/Metric Reading/Standard 2% Accuracy table. A note under that table says the listed wrenches ship without a certificate of calibration. Elsewhere on the Torqometer pages, Snap-on adds that a C suffix orders the certificate models. So the TEC50AC sits on the TEC50A row, and the paper trail is the change. Lost in HCM calls that extra item a chart, but its listing does not describe what it holds.
Who should pick the Snap-on TEC50AC dial wrench
- A tier-2 supplier faces a customer process audit and must show a record for each torque tool.
- Your receiving clerk logs a document number before any gauge enters the tool crib.
- QA uses the wrench to audit joints that operators tightened, so its own status must sit on file.
- Launch dates leave no time to send a new tool out for a first check.
Where the TEC50A without a chart is enough
Some plants own a torque tester and verify every new wrench before release. Others ship each new tool to a contracted lab on arrival. In both cases, the lab report becomes the record, so a factory chart adds little. A spare wrench for a repair bench may also need only a cross-check. For those buyers, the TEC50A leaves more budget than the TEC50AC for sockets and adaptors.
Snap-on TEC50AC dial wrench: the shared TEC50A row
| Item | CAT1500i value (TEC50A row) |
|---|---|
| Square drive | 3/8 in |
| Metric scale | 700 kg·cm, 20 kg·cm steps |
| US scale | 600 in-lb, 20 in-lb steps |
| Length / width | 12-1/2 in / 2-11/16 in |
| Head depth (without drive) | 1-1/4 in |
| Storage case | PB9 |
Being a Basic model, the TEC50AC carries a single needle, and it shows the torque achieved. Snap-on’s UK brochure gives the Standard 2% grade as within 2% of reading from 20% of full scale to full scale, in both directions. Therefore plan most work above 140 kg·cm or 120 in-lb on this dial.
Keeping the TEC50AC and its chart in order
Keep the TEC50AC in its PB9 case whenever it leaves the bench. Also, stay within the rated torque, and never use it to break a fastener loose. Snap-on notes that periodic recalibration keeps a Torqometer accurate. Enter the wrench in your recall list on the day it arrives, next to the chart.
TEC50AC on your purchase request: what to write
Quotes for the chart code come from Lost in HCM, which supplies Snap-on Torqometers to Vietnamese plants. Write TEC50AC in full on your request, because the plain code ships without the chart. When the paperwork need is clear, ask Lost in HCM to quote the TEC50AC. You can also browse more torque wrenches on SMK Vietnam or contact SMK Vietnam for help.
TEC50AC paperwork questions
Does the chart alter the TEC50AC dial?
No. Snap-on prints one catalog row for the TEC50A, so the drive, scales and length stay the same.
Can I ask what the chart includes before I buy?
Yes. The listing does not describe it, so ask Lost in HCM for a sample before you place the TEC50AC order.
Is there a TEC50 with two needles?
Yes. The same CAT1500i row lists the TEC50FUA follow-up model and the TEC50LA signal model.
