Description
A small satellite must survive launch vibration with every screw still at its set torque. Space labs and university teams in Vietnam now build cubesats and payload boards for that test. The Snap-on TQSI135FUA torque driver gives their assemblers a measured value on each light screw. Its full-length body carries an N·m dial and a follow-up needle.
Satellite builds and the Snap-on TQSI135FUA torque driver
Satellite drawings list a torque for each structure, bracket and board screw, usually in N·m. Because a flight unit needs proof, many teams record every value in a build log. With this driver, the assembler tightens to the drawing value and reads the held needle. Then the number goes into the log with the screw location. In addition, the same driver can recheck screws after a vibration test.
Snap-on data for the TQSI135FUA
| Item | TQSI135FUA |
|---|---|
| Model type | Standard follow-up (2 needles) |
| Scale | Newton meters (US/Newton Meter driver family) |
| Stubby twin | TQSSI1.35FUA |
Snap-on lists this row in the Combination US/Newton Meter driver table of catalog CAT1500i. Per that table, a C at the end of the stock number orders the certificate version. So the base TQSI135FUA comes without a certificate. Teams that want a 1% grade can ask about Snap-on’s Precise models, which come on special order.
TQSI135FUA or the stubby twin?
The full-length body gives a steady two-finger grip on an open bench. By contrast, the stubby TQSSI1.35FUA suits screws deep inside a frame. Ask Lost in HCM to confirm the full-scale value of each before you order. So choose by reach, and keep one style per station to avoid mix-ups.
Where the TQSI135FUA reads best
Snap-on states the 2% guarantee for its standard grade from one-fifth of full scale up to full scale. Therefore pick a driver whose usual targets sit in the upper part of the dial. For the Snap-on TQSI135FUA torque driver, ask Lost in HCM to confirm the full-scale value and the dial steps with your quote. For the very smallest screws, a lower-range driver will read finer.

TQSI135FUA space lab FAQ
Why does the code read TQSI135FUA without a decimal point?
Snap-on prints it that way in CAT1500i, while its stubby twin carries the point as TQSSI1.35FUA. Ask Lost in HCM to confirm the full-scale value with your quote.
Is the TQSI135FUA approved for flight hardware?
The listing claims no space or cleanroom approval. Follow your own product assurance plan for tool acceptance and cleaning.
What paperwork can we get for incoming inspection?
Per the catalog, adding C to the code orders the certificate version. Ask Lost in HCM whether the TQSI135FUAC suits your plan.
