Snap-on TQS004FUA Torque Driver, Torqometer U.S. Follow-up Dial, 8 in-oz, 1/4″ Drive

Description

Hospital biomedical engineering teams service infusion pumps, patient monitors and probe housings on their own benches. Many of those parts close with tiny screws in thin plastic, so a slip of torque can crack a case. The Snap-on TQS004FUA torque driver works in that very light zone. It reads up to 8 in-oz on a U.S. dial, and two needles show the target and the result.

The smallest dial in the chart

Snap-on’s US Reading driver chart starts with the TQS004 row. Its 8 in-oz scale equals half an inch-pound, or about 5.6 N·cm. So the TQS004FUA sits below every other US Torqometer driver in that table. In practice, that suits screws where a normal driver gives the hand no feedback at all.

TQS004FUA catalog row

The row appears in Snap-on’s US Reading Standard/2% Accuracy driver table. That table also lists a stubby TQSS004FUA at 5-3/4 inches with the same scale. In addition, the catalog says these drivers ship without a certificate, and a C on the stock number orders one.

Biomed bench jobs for the Snap-on TQS004FUA torque driver

• Housing screws on infusion and syringe pumps, where the service manual gives a value.
• Display bezel and battery door screws on monitors.
• Small board and connector screws inside handheld devices.
• Probe and sensor housing screws in thin plastic.

However, device makers set their own values and test steps after repair. So follow the service manual, and run the maker’s checks before the unit goes back to a ward.

Using the TQS004FUA band well

Lost in HCM files the TQS004FUA under US Reading Standard/2% Accuracy. Snap-on’s Torqometer guarantee covers 2% of reading from 20% of full scale to full scale. Thus, on this dial, the band opens at 1.6 in-oz. If a target sits near the top, the 16 in-oz TQS008FUA gives more headroom.

Clean bench routine

Clean the device per your infection control rules before you open it. Then zero the result needle before each screw, since it holds the last value. Turn slowly as the screw seats, because a quick twist overshoots at this scale. Afterward, wipe the TQS004FUA, return it to its PB47 case, and set a recalibration date.

Biomed technician FAQ for the TQS004FUA

Is there a shorter version of the TQS004FUA?

Yes. Snap-on lists the stubby TQSS004FUA at 5-3/4 inches with the same 8 in-oz scale.

What is the TQS004FUA’s 8 in-oz in N·m?

In other words, it is half an inch-pound, or about 0.056 N·m. That equals roughly 5.6 N·cm.

Can the TQS004FUA replace the device maker’s test after repair?

No. The driver only shows screw torque. The maker’s safety and function tests still apply.
