Snap-on TEC3FUAC Torqometer, U.S./Metric Follow-up Dial Wrench, 1/4″ Drive, 30 in-lb / 35 kg·cm, with Chart

Description

Garment and footwear plants in Vietnam run hundreds of industrial sewing machines on each floor. When a needle bar, hook or presser foot drifts, a mechanic has minutes to fix it before the line backs up. The Snap-on TEC3FUAC Torqometer gives that mechanic a measured hand on small screws. It reads in inch-pounds and kilogram-force centimeters, and its second needle helps with the check.

Small screws, big line stops

A set screw that slips lets a hook timing drift, and then stitches skip. On the other hand, a screw driven too hard can crack a casting or strip a soft thread. So a dial wrench sits between those two faults. With the TEC3FUAC, the mechanic sees the load rise and stops at the value the service manual gives.

Two needles on the Snap-on TEC3FUAC Torqometer

Snap-on describes its Follow-up models as having two separate needles. One shows the targeted torque, and the other shows the torque achieved. So a senior mechanic can set a target, hand the tool to a trainee, and then compare the two needles after each pull.

Specs from the TEC3FUA row

Snap-on’s catalog says a trailing C orders the documented version of a stock number, and that explains the TEC3FUAC code. In addition, Lost in HCM’s title says the unit comes with a chart.

Where the TEC3FUAC fits in a sewing shop

• Needle bar and needle clamp screws.
• Rotary hook and looper set screws after timing work.
• Presser foot, feed dog and throat plate screws.
• Small motor and pulley cover screws on servo drives.

In fact, many machines in these plants come from Japanese makers. Their service data often gives torque in kgf·cm, so the metric scale saves a conversion step.

Grade and band for the Snap-on TEC3FUAC Torqometer

Lost in HCM lists this wrench under Combination US/Metric Reading/Standard 2% Accuracy. Snap-on applies it across 20% to 100% of full scale. Here the band therefore starts at about 7 kg·cm or 6 in-lb. For reference, 35 kg·cm is roughly 3.4 N·m.

Care on the shop floor

In a sewing hall, lint and machine oil also get everywhere. So keep the Snap-on TEC3FUAC Torqometer in its case on the mechanic’s cart, and wipe the dial glass often. Also never use it to loosen a stuck screw. Plan outside recalibration at a fixed interval, too.

TEC3FUAC sewing machine FAQ

Is 30 in-lb enough for sewing machine screws?

For many small set screws and clamps, yes. Check the maker’s value, because some frame bolts need a larger wrench.

Why kg·cm and not N·m?

Snap-on’s U.S./metric dial uses kilogram-force units. That suits service data printed in kgf·cm.

What does the TEC3FUAC chart include?

Lost in HCM’s title says with Chart but does not describe it. So check with Lost in HCM before you order.
