Description
The Snap-on TQS4FUA torque driver appears here under its plain code, as Lost in HCM’s U.S. Follow-up Torque Driver. Buyers who need a document with the tool should open the TQS4FUAC listing with chart. Otherwise, the two codes describe one 50 in-lb driver with an 8-11/16 inch body.

One dial, two listings for the TQS4FUA
Snap-on’s driver table explains the split in one line. Codes in the chart come without a certificate of calibration, while a final C orders one. Therefore the TQS4FUA keeps the needles, the scale and the handle of its twin.
Choose the TQS4FUA when
- your plant sends each new gauge to an outside calibration provider before first use
- the driver joins a maintenance kit rather than a final-test station
- budget matters more than a record on delivery day
Choose the TQS4FUAC when
- an auditor will ask for a certificate during the first visit
- incoming inspection holds back tools that arrive with no document
- the driver goes straight to a release station with no lab slot
The square drive inside the Snap-on TQS4FUA torque driver handle
A footnote in the table marks this size with a 1/4 inch internal square drive in the handle. So a technician can work with 1/4 inch square-drive accessories at the handle end. Before you order, confirm the fit of your adaptors with Lost in HCM.
TQS4FUA numbers in brief
Snap-on lists the TQS4FUA as a Standard Follow-up model with two needles. Its dial reads to 50 in-lb in 1 in-lb steps. In addition, the body measures 8-11/16 inches, longer than the 7-3/4 inch lower sizes. A PB47 storage case comes with it, and the table carries the heading Standard 2% Accuracy.
On the Snap-on TQS4FUA torque driver, keep most targets near the middle of the dial, around 25 in-lb, as the UK brochure advises. Below 10 in-lb, which is 20% of full scale, a smaller size will serve you better.

TQS4FUA FAQ
Will the plain TQS4FUA pass our audit?
That depends on your quality plan. If it calls for a certificate on arrival, order the C code or book an outside check before first use.
Is there a stubby version at 50 in-lb?
Yes. Snap-on lists the TQSS4FUA with a 5-1/4 inch body in the same row of the table.
What should we avoid with this driver?
Snap-on warns users not to exceed rated torque and not to break fasteners loose with Torqometer tools.
