Description
An electric scooter carries dozens of small screws, from display mounts to controller lids. Plastic bosses crack when a screw goes too tight, while a loose cover lets rain reach the electronics. The Snap-on TQS2A torque driver gives assemblers a live dial reading up to 24 in-lb. So every value on the work sheet becomes a number instead of a feel.
E-scooter assembly jobs for the Snap-on TQS2A torque driver
Vietnam now builds two-wheel EVs in volume, and a 24 in-lb dial covers much of their light hardware. Typical TQS2A checks include:
- Display and throttle housing screws on the handlebar.
- Headlight and tail light bracket screws.
- Controller box and battery cover lids that seal on a gasket.
Stem clamps and axle nuts sit far above this scale, so leave them to a torque wrench.
What a basic Torqometer dial tells you
The TQS2A is a basic model, which means one needle that moves while you turn. It does not click or slip by itself. Instead, the operator watches the needle and stops at the target. Because the value stays visible, an engineer can also watch how a screw seats on its gasket.
Figures Snap-on prints for the TQS2A
| Item | Snap-on data |
|---|---|
| Full scale | 24 in-lb, also marked as 384 in-oz (near 2.7 N·m) |
| Smallest mark | 1/2 in-lb or 8 in-oz |
| Body length | 7-3/4 inches, standard |
| Dial type | U.S. units, single live needle |
| Storage case | PB47 |
Snap-on states 2% of the reading from 20% of full scale up to full scale, in both directions. On the TQS2A, that band starts near 4.8 in-lb. Below that point, a smaller dial such as the 12 in-lb TQS1A reads better.
The Snap-on TQS2A torque driver and its row mates
Snap-on prints four drivers on the same 24 in-lb row of its U.S. chart. The TQSS2A keeps the scale but shortens the body to 5-1/4 inches for deep housings. Meanwhile, the TQS2FUA adds a second needle that holds the peak. Choose the TQS2A when screws are easy to reach and the operator wants a fuller grip. If your target sits above 24 in-lb, the 30 in-lb TQS2.5A is the next step up.
Keeping the TQS2A reliable on a busy line
Rack the driver away from the conveyor, since a drop onto concrete can upset the needle. At shift end, wipe off grease and plastic dust, then return the TQS2A to its PB47 case. In addition, log each periodic check in your quality plan. The plain code ships without a certificate, yet Snap-on offers a certified version when you add C to the stock number.
EV line questions about the TQS2A
Can the TQS2A tighten screws into plastic bosses?
Yes, as long as the target sits inside its scale. The dial will not stop you, so read the needle and stop at the value on your work instruction.
How do I use the 24 in-lb scale with metric drawings?
Convert the drawing value first. One in-lb is about 0.113 N·m, so the full TQS2A scale equals about 2.7 N·m.
Should our line use the TQS2A or a preset clutch driver?
Use a preset clutch driver for fast repeat work. Then use the TQS2A to set up and audit those tools, because it shows the actual value.
