Description
The CDI 4004MFRMH torque wrench gives maintenance teams a dual-scale tool for big fasteners. It has a 3/4″ square drive and reads 80-400 ft-lb, or 85-491 N·m. So one wrench covers wheel nuts, flange bolts and frame joints that a 1/2″ tool cannot reach.
Why choose the CDI 4004MFRMH torque wrench
CDI Torque Products is the industrial torque brand of Snap-on. Its adjustable wrenches give a clear click when the set value is reached. As a result, the operator stops pulling at the right point and the joint gets a repeatable load.
The dual scale also helps mixed teams. For example, an engineer can read a US drawing in ft-lb, while a technician checks a European spec in N·m on the same handle.
Where it fits on the shop floor
- Truck, bus and forklift wheel nuts and suspension bolts.
- Press, pump and gearbox mounting bolts in plant maintenance.
- Steel structure and tower bolting before a final audit.
- Incoming checks on joints that a supplier assembled.
In practice, a 3/4″ wrench like this one sits between a 1/2″ shop wrench and a torque multiplier. Therefore it is often the main tool for heavy work in one team.
Choosing the right range
Pick a range that puts your usual target in the middle of the scale. Click wrenches work best between about 20% and 100% of full scale. So if most of your joints need 150-350 ft-lb, this model is a good match. However, if your targets sit near 100 ft-lb, a smaller CDI model will give better resolution.
Care and accuracy over time
Every click wrench drifts with use. For that reason, set it back to the lowest value after each shift, because a loaded spring loses tension faster. Also keep it in its case and never use it to break bolts loose. Most plants send torque tools for an independent calibration check once a year, or sooner after a drop.
