Snap-on TEXC2003TFUC Torqometer, U.S./Metric Follow-up T-Handle, 2,000 ft-lb / 280 kg·m, 1″ Drive

Description

Rail depots check bolts long after a train leaves the shop. Vibration, heat and load can all loosen a joint over time. The Snap-on TEXC2003TFUC Torqometer helps crews measure what is left. This one is a follow-up T-handle head that reads in both U.S. and metric units. Its listing also names a chart.

Breakaway audits with the Snap-on TEXC2003TFUC Torqometer

A breakaway audit measures how much torque a tightened bolt still holds. First, the inspector pulls slowly in the tightening direction. Then the needle climbs until the nut just starts to move. At that moment, the follow-up needle keeps the peak, so the inspector can stop and read it. This differs from removal, because Snap-on warns not to use Torqometers to break fasteners loose.

Rail work that suits a 2,000 ft-lb head

• Residual torque checks on bogie and suspension bolts in rolling stock depots.
• Audits of coupler and drawgear bolts after overhaul.
• Spot checks on large bolts in track and switch maintenance.

In each case, the crew records a value from the TEXC2003TFUC, not just a pass mark. As a result, a trend shows up across inspections.

Range, drives and handles

Snap-on’s CAT1500i catalog lists the TEXC2003TFU with a 1-inch female input and a 1-inch male output. The U.S. scale reaches 2,000 ft-lb in 50 ft-lb steps, and the metric scale reaches 280 kg·m in 5 kg·m steps. In addition, Snap-on’s 2005 Torqometer listing shows the same 2,000 ft-lb capacity and 1-inch drives. The trailing C, per the catalog, marks the version sold with a certificate of calibration.

Why a T-handle helps under a rail car

Space under a bogie is tight, and a long dial wrench is hard to swing there. The TEXC2003TFUC head is short, so a T bar or extension handle can sit where the room allows. Also, with both hands on a T bar, the inspector can pull smoothly, which keeps the breakaway reading clean.

2% grade on the TEXC2003TFUC

Lost in HCM groups this model under Combination US/Metric Reading/Standard 2% Accuracy. Snap-on defines that grade as within 2% of reading from 20% of full scale to full scale. Therefore readings above about 400 ft-lb fall inside the band. Below that, a smaller Torqometer gives better results.

Upkeep between inspections

Reset the follow-up needle before every bolt. Keep the Snap-on TEXC2003TFUC Torqometer in its case on the inspection cart, away from rain and brake dust. Then store the chart with your audit files, and send the head for outside calibration on your depot’s cycle.

TEXC2003TFUC rail audit FAQ

How do I run a breakaway check without harming the joint?

Pull slowly in the tightening direction and stop as soon as the nut starts to turn. The follow-up needle then shows the peak at first movement.

Is this the same tool as the TEXC2003TFU in Snap-on’s tables?

Snap-on’s catalog says adding a C to a stock number orders the certified version. So the TEXC2003TFUC should match the TEXC2003TFU specs; confirm with Lost in HCM.

What handle fits the 1-inch input?

Snap-on lists the 82TQP T bar and the 85TQP extension handle as options for this size. Ask Lost in HCM which one it can supply.
