Snap-on TQSR6FUA Torque Driver, Torqometer U.S./Newton Meter Follow-up Dial, 75 in-lb / 8.4 N·m, 1/4″ Drive

Description

Aircraft maintenance manuals often give fastener torque in both inch-pounds and newton meters. The Snap-on TQSR6FUA torque driver shows both on one dial, so hangar technicians skip a conversion step. It is a full-length Torqometer driver with a follow-up needle that holds the peak. Lost in HCM files it under its 1/4-inch drive Torqometer drivers.

Avionics bays and the Snap-on TQSR6FUA torque driver

Avionics shelves hold radios, computers and connectors on racks that face steady vibration. So the screws on mounting trays, clamp blocks and access panels each have a set value. With this driver, the technician tightens to that value and then reads the held needle. Next, the value goes onto the work card before the panel closes. In addition, the second needle helps when a lead inspector wants to see the reading.

Catalog values for the TQSR6FUA

Snap-on prints these numbers in the Combination US/Newton Meter table of catalog CAT1500i. Snap-on’s 2005 Torqometer announcement also lists the TQSR6FUA at 8-11/16 inches with the same square drive note. The CAT1500i table also states that its drivers carry no certificate unless you add a C to the stock number.

Range and steps on the TQSR6FUA

Snap-on holds its standard grade within 2% of reading from 20% of full scale to full scale. For this dial, that window opens near 1.7 N·m, or 15 in-lb. So the driver suits values from there up to 8.4 N·m. However, the steps are coarse at 0.2 N·m or 5 in-lb. For small connector screws, a lighter size such as the TQSR1FUA reads finer. Snap-on also notes that Precise 1% models come on special order.

Tool control for the TQSR6FUA

Most maintenance organizations track each torque tool by serial number and due date. Therefore log the Snap-on TQSR6FUA torque driver in your tool crib like any other gauge. Also zero the follow-up needle before each fastener, and keep the bit in line with the screw. The listing makes no claim of aviation approval, so follow your own quality manual for tool acceptance.

Hangar FAQ

Does the TQSR6FUA include a certificate?

No, the base code has no C. Ask Lost in HCM whether the C version suits your tool acceptance process.

What fits the square drive in the handle?

Snap-on lists a 1/4-inch internal square drive in this handle. A short bit holder or socket adapter fits there, but keep the stack short for a steady reading.

Can it replace a preset torque screwdriver?

For audits, yes, because the dial shows the number you reached. For fast repeat work, many shops still prefer a preset tool.
