CDI 6004MFRMH Torque Wrench, 3/4″ Drive, 100-600 ft-lb (169-779 N·m)

Description

When a job outgrows a 400 ft-lb tool but does not justify a 1-inch drive, the CDI 6004MFRMH torque wrench is the natural step. It uses a 3/4-inch square drive and sets from 100 to 600 ft-lb. A second scale reads 169-779 N·m, so you can follow either unit on the drawing.

What sets the 6004MFRMH apart

The CDI 6004MFRMH torque wrench gives you real reach at the top of the 3/4-inch class. Because the range starts at 100 ft-lb, it still handles medium joints on the same machine. That means one wrench can cover the base bolts and the flange bolts of a pump set. CDI Torque Products, a Snap-on company, builds it as an adjustable click wrench.

How to use it, step by step

• Unlock the handle and turn it until the scale shows your target.
• Lock the handle again, then fit a 3/4-inch drive socket.
• Pull slowly and steadily at the grip, at a right angle to the handle.
• Stop as soon as you feel and hear the click.
• Wind the setting back down when the task ends.

Industries that rely on 3/4-inch torque

For instance, power and backup generator sets carry many joints in this band, from engine mounts to coupling bolts. Construction fleets also need it for track and frame bolts on mid-size machines. In addition, water and chemical plants use it on large pump and valve flanges. For example, a maintenance team might tighten a flange in a set pattern, then recheck each bolt in a second pass.

Sizing tip

As a rule, choose a range where your common targets land well above the lowest mark. If most values sit near 100 ft-lb, a smaller CDI model will give a finer feel. However, if they run between about 300 and 600 ft-lb, this wrench is a strong match.
