Snap-on TER1FUAC Torqometer, US/N·m Follow-up Dial Wrench, 1/4″ Drive, 1.7 N·m / 15 in-lb, with Calibration Certificate

Description

Chip assembly and test plants in Vietnam run thousands of test sockets and load boards each day. Each socket lid, stiffener and board screw needs an even, light load. Otherwise, the pins and pads stop making good contact. The Snap-on TER1FUAC Torqometer measures that load on a dial marked in newton meters and inch-pounds. It also belongs to Snap-on’s Precise 1% family, and the listing adds a calibration certificate.

Why the test floor cares about light torque

In practice, a test socket presses many spring pins against a board. If one corner screw runs tighter than the rest, the board can bow, so some pins lose contact. As a result, good parts may fail and bad ones may slip through. So engineers can use the Snap-on TER1FUAC Torqometer to confirm that each screw reached the same value.

Snap-on TER1FUAC Torqometer: TER1FUA row

The table lists the base code TER1FUA. As the catalog explains, a C on the end of the stock number orders the version with a certificate of calibration. Thus the TER1FUAC is that C form, and the Lost in HCM title names the certificate too.

Socket and board tasks

• Socket lid and hinge screws during changeovers.
• Board stiffener and backing plate screws.
• Alignment plate screws on handler change kits.
• Bench checks of electric drivers used on load boards.

Still, always use the value from the socket or board maker. If it sits within the TER1FUAC dial, the wrench can confirm it on the line or at the bench.

Precise grade on a small scale

Lost in HCM lists this model under Combination US/Newton Meter Reading/Precise 1% Accuracy. Snap-on’s Precise rating means readings within 1% from 20% of full scale to the top of the dial. On the TER1FUAC, that band starts at 0.34 N·m, or 3 in-lb. Below that, however, a Torqometer driver may suit better.

Two needles and a certificate

Follow-up models, per Snap-on, use two needles: one for the targeted torque and one for the torque achieved. Therefore a test engineer can record both after each screw during a socket audit. The calibration certificate also gives the quality team a TER1FUAC document to file with the tool list.

Cleanroom habits for the Snap-on TER1FUAC Torqometer

The source does not describe ESD properties, so follow your plant’s ESD rules for metal hand tools. Also wipe the wrench with an approved cleaner before it enters a clean area. Never use it to free a stuck screw, and book periodic recalibration with an outside lab.

Test floor questions about the TER1FUAC

What does 1.7 N·m equal in in-lb?

About 15 in-lb. In fact, Snap-on’s row prints that 15 in-lb scale on the same TER1FUAC dial.

Can it drive screws directly?

It has a 1/4 inch square drive, so fit a suitable bit holder for the screw head.

What does the certificate state?

The source only says the wrench comes with a calibration certificate. Lost in HCM can share the details.
