Cdi Torque 6004MFRPH Torque Wrench 3/4 in Drive 100-600 Ft Lb

Product Description

The CDI TORQUE 6004MFRPH is a 3/4 inch drive click-style torque wrench with a dual-scale, dual-direction calibrated mechanism designed for high-torque fastening applications. It covers a range of 100 to 600 ft lb with a 5 ft lb increment resolution, making it suitable for heavy-duty service work including large HVAC equipment, commercial refrigeration systems, and industrial mechanical assemblies. The wrench features a positive locking mechanism with a spring-loaded pull-down lock ring and an ergonomic comfort grip. It ships individually serialized with a matching certificate of calibration traceable to N.I.S.T.

This wrench is built for licensed mechanics and field technicians who need repeatable, code-compliant torque in demanding environments. The 3/4 inch drive size suits large-fastener applications where smaller drive wrenches lack the mechanical advantage to reach target values safely. Typical use cases include compressor mounting, large flange assemblies, and structural bolting on commercial HVAC and industrial mechanical systems. The laser-marked scale supports quick, legible readings under field conditions.

Key Features

• Dual-scale, calibrated dual-direction operation for clockwise and counterclockwise torque application
• Accuracy of 4 percent CW and 6 percent CCW of indicated value from 20 percent to 100 percent of full scale
• Spring-loaded pull-down lock ring prevents accidental setting changes during use
• Laser-marked scale for clear, durable readability in the field
• Quick-release button provides positive socket retention and easy socket removal
• Meets or exceeds ASME and ISO 6789 standards
• Individually serialized with N.I.S.T.-traceable calibration certificate included

Compatibility

Designed for use with standard 3/4 inch drive sockets and accessories. Suitable for heavy-duty mechanical and industrial fastening applications requiring torque values between 100 and 600 ft lb.

Installation Notes

A licensed mechanic or qualified technician should verify that the correct torque specification for the fastener is known before use. Always return the wrench to its minimum setting after use to preserve calibration and spring tension. Do not use extension bars or cheater pipes on the handle, as this will introduce inaccurate torque readings and may void the calibration certificate. Handle with care to avoid drops, which can affect calibration accuracy.
