Description
Printers, copiers and label machines hold their print heads, rollers and sensors with very small screws. Office equipment plants in Hai Phong, Hung Yen and Dong Nai build them, and service teams across Vietnam keep them running. The Snap-on TEC1A dial wrench gives both groups a way to measure those light loads. Its 1/4-inch drive dial reads up to 16 kg·cm and 15 in-lb.
A dial for printer and copier screws
A head bracket screw that runs too tight can warp a frame by a hair, and then print lines blur. Too loose, by contrast, and the part shifts after a few thousand pages. So assembly engineers set driver clutches, and QC confirms them on sample units with the TEC1A. Field technicians can also carry it in a service case for audits at large accounts.
- Print head and carriage bracket screws.
- Fuser and roller frame screws on copiers.
- Sensor and encoder board screws.
- Small motor and gear plate screws on label printers.
The Snap-on TEC1A dial wrench row, line by line
| Item | TEC1A (Snap-on CAT1500i p.335) |
|---|---|
| Square drive | 1/4 in |
| Metric range / steps | 16 kg·cm / 1 kg·cm |
| US range / steps | 15 in-lb / 0.5 in-lb |
| Length | 9-29/32 in |
| Width / head depth | 2-11/16 in / 1-1/4 in |
| Storage case | PB9 |
Snap-on lists this code in its Combination US/Metric Reading/Standard 2% Accuracy chart. In addition, the chart note says these stock numbers ship without a certificate of calibration, while a certificate version exists.
Two top marks that differ a little
On paper, 15 in-lb equals about 17.3 kg·cm, yet the metric scale on the TEC1A stops at 16 kg·cm. So do not convert from one top mark to the other. Instead, read the scale that matches your drawing. Japanese service data often quotes kgf·cm, while many US parts lists use in-lb.
One needle on the TEC1A, two on the TEC1FUA
The Basic TEC1A has one needle, and Snap-on says it shows the torque achieved. That works well when the person pulling also reads the dial. However, if a QC lead wants to check the value after release, the TEC1FUA adds a follow-up needle. Both share the same drive, scales and body length.
Looking after the Snap-on TEC1A dial wrench
Toner dust and paper fibers drift into every corner of a copier line. Therefore, keep the Snap-on TEC1A dial wrench closed in the PB9 case Snap-on lists for it, and wipe the dial glass often. Also zero-check it before each audit. Snap-on warns against using it to break fasteners loose, so free tight screws with a hand driver. Then plan recalibration with an outside lab at a fixed interval.

Printer and copier FAQ on the TEC1A
How small a screw can the TEC1A check with confidence?
Snap-on rates accuracy from 20% of full scale. So the useful floor sits near 3.2 kg·cm or 3 in-lb on this dial.
Can the TEC1A be ordered with a signal lamp?
No. Snap-on shows no signal model for this row. The TEC1FUA, with a follow-up needle, is the only variant listed.
Will a 1/4-inch drive take our screwdriver bits?
Yes, with a 1/4-inch square to hex bit adapter. Keep the adapter short, so the bit stays square to the screw.
