Cdi 4004MFRMH Micrometer Torque Wrench 85-491 Nm

Product Description

The CDI 4004MFRMH is a micrometer-style torque wrench designed for high-torque fastening applications in professional trade and industrial environments. It covers a working range of 85 to 491 Newton-meters (Nm), with a graduation of 3.4 Nm for precise setting. The wrench measures 34.25 inches in overall length, features a pear-shaped head, and includes a knurled handle for secure grip. Clockwise accuracy is rated at 4 percent and counterclockwise accuracy at 6 percent. Dual laser-marked scales make readings fast and clear. A positive lock mechanism holds the set value during use, and a quick-release button simplifies socket changes. This tool is intended for use by mechanics, technicians, and tradespeople who require calibration-certified torque output in demanding service conditions.

The 4004MFRMH is suited for heavy-duty fastening tasks where both clockwise and counterclockwise torque application is required. Typical applications include large engine assembly, drivetrain service, structural bolting, and industrial equipment maintenance. The dual-scale readout supports both metric and English torque values, accommodating multi-standard work environments. At 14.39 pounds, this wrench is built for bench or floor use rather than overhead work. It ships individually and is intended for single-user professional service.

Installation Notes

This wrench should be operated by qualified mechanics or technicians familiar with torque-controlled fastening procedures. Always set the torque value before engaging the fastener and engage the positive lock before use. Store the wrench at its minimum torque setting to preserve internal spring calibration. Periodic recalibration is recommended per the manufacturer schedule or as required by applicable quality or safety standards.
