Cdi 6004MFRMH Adjustable Torque Wrench 169-779 Nm 42 in

Product Description

The CDI 6004MFRMH is a micrometer-style adjustable torque wrench designed for precision fastening applications across a wide torque range. It spans from 169 to 779 Newton-meters (Nm), with a fine graduation of 6.8 Nm, making it suitable for jobs that demand accurate, repeatable torque values. The wrench measures 42 inches in overall length and supports both clockwise and counterclockwise rotation. It ships with a calibration certificate, confirming factory-verified accuracy before it reaches the field. Licensed mechanics, HVAC technicians, plumbers, and industrial tradespeople who routinely torque flanges, fittings, or structural fasteners will find this tool fits standard professional workflows.

This torque wrench suits residential and commercial trade applications where high-torque, dual-direction fastening is required. Typical use cases include tightening large pipe flanges, equipment mounting bolts, and structural connections on mechanical systems. The dual-scale laser-marked barrel allows technicians to read Nm and Ft/Lb values without conversion, reducing the chance of setting errors on the job. The positive lock mechanism holds the set value through the fastening sequence, and the quick-release button speeds up socket changes in tight work areas.

Key Features

• Micrometer-style adjustment with a torque range of 169 to 779 Nm (100 to approximately 574 Ft/Lb)
• 6.8 Nm graduation for fine, precise torque settings
• Dual-scale laser-marked barrel displays Nm and Ft/Lb simultaneously
• Clockwise accuracy of 4 percent; counterclockwise accuracy of 6 percent
• Positive lock prevents accidental adjustment once target torque is set
• Quick-release button for fast socket changes
• Ships calibration certified for immediate use in verified-torque applications

Compatibility

Designed as a general-purpose micrometer torque wrench for professional trade use wherever a high-torque, dual-direction wrench with calibration certification is specified.

Installation Notes

This tool is intended for use by qualified tradespeople familiar with torque specifications for the fasteners and assemblies being serviced. Always set the wrench to the lowest torque value when storing to preserve internal spring calibration. Do not exceed the maximum rated torque of 779 Nm, and do not use the wrench as a breaker bar or cheater extension. Calibration should be verified periodically per your shop or jobsite quality-control schedule.
