Snap-on TEC51FU Torqometer, U.S./Metric Follow-up Dial Torque Wrench, 1/2″ Drive, 600 in-lb / 700 kg·cm

Description

Air-conditioner and compressor plants in Vietnam build to Japanese, Korean and American drawings. So a single audit team may face kg·cm on one line and in-lb on the next. The Snap-on TEC51FU Torqometer reads both on a follow-up dial, with a 1/2-inch drive and a 600 in-lb, 700 kg·cm full scale.

Why the follow-up needle helps auditors

Snap-on describes its follow-up models as having two separate needles. They show the targeted torque and the torque achieved. As a result, the auditor can finish the pull, then read the held value calmly. That makes the TEC51FU a good fit for residual torque checks on joints that a nutrunner already tightened.

A simple check routine with the Snap-on TEC51FU Torqometer

• Reset the follow-up needle to zero before each joint.
• Mark the bolt head and the part with a paint line.
• Pull slowly in the tightening direction until the mark just moves.
• Note the held reading in kg·cm or in-lb, to match the drawing.

Your quality plan sets the exact method, so follow it first.

What the TEC51FU row shows

Source: Snap-on CAT1500i, Combination US/Metric Reading/Standard 2% Accuracy table. Both full-scale values land close to 68 N·m.

Why pick 1/2-inch over the 3/8-inch twin

The same Snap-on table lists a TEC50FUA with the same scales on a 3/8-inch drive and a 12-1/2 inch body. The TEC51FU, by contrast, offers a 1/2-inch drive and a 15 inch length. So it suits teams whose sockets are 1/2-inch, and joints where a longer handle eases the pull. Snap-on’s brochure rates the Standard 2% grade from 20% of full scale. Therefore its useful band starts near 140 kg·cm or 120 in-lb.

Looking after an audit Torqometer

Wipe compressor oil off the grip before you store the wrench. In addition, keep it in a padded drawer or case, since the table lists no case for this row. Never exceed 600 in-lb, and never use it to free a seized bolt. Finally, plan periodic recalibration with an outside lab, as Snap-on advises.

FAQ on the TEC51FU

Can the TEC51FU show N·m?

Not directly. Its metric scale reads kg·cm, so multiply by 0.098 to get N·m.

Is the TEC51FU a good first audit wrench?

Yes, for joints between about 140 and 700 kg·cm. Below that, choose a smaller dial so the reading stays in the 2% band.
