Cdi Torque 501MRMH Torque Wrench 10-50 in Lb 1/4 in Drive

Product Description

The CDI TORQUE 501MRMH is a 1/4 inch drive click-style torque wrench built for professional trade use. It covers a torque range of 10 to 50 inch-pounds in 0.5 inch-pound increments and features an overall length of 10.15 inches. The metal handle is lightly knurled for a firm, non-slip grip during repetitive or high-force applications. Accuracy is rated at 4 percent clockwise and 6 percent counterclockwise of indicated value, measured from 20 percent to 100 percent of full scale. Each unit is individually serialized and ships with a certificate of calibration traceable to N.I.S.T. This wrench is suited for HVAC technicians, plumbers, electricians, and mechanical service professionals who require reliable, repeatable torque output on fasteners in tight or critical assemblies.

The 501MRMH is designed for applications requiring precise low-range torque control, including equipment panels, access covers, fittings, and small fastener assemblies common in HVAC, plumbing, and light mechanical service work. The compact 1/4 inch drive size makes it practical for confined-space fastening tasks. The dual-scale, bidirectional calibration supports both clockwise and counterclockwise torque application without swapping tools. A quick-release button provides consistent socket retention and fast socket changes during production or service work.

Key Features

• Torque range: 10 to 50 inch-pounds with 0.5 inch-pound graduation increments
• Dual scale, calibrated for dual direction (clockwise and counterclockwise)
• Positive lock with spring-loaded pull-down lock ring prevents accidental setting changes
• Laser-marked scales for clear, accurate reading in field conditions
• Quick-release button for reliable socket retention and easy socket removal
• Individually serialized with N.I.S.T.-traceable certificate of calibration included

Compatibility

Designed for use with standard 1/4 inch drive sockets. Suitable for any fastening application within the 10 to 50 inch-pound torque range.

Installation Notes

Store and transport the wrench set to the lowest torque value on the scale to preserve the internal spring mechanism. Do not use this wrench as a breaker bar or for loosening fasteners beyond its rated range. Recalibration at regular service intervals is recommended per tool manufacturer guidelines and applicable quality or compliance programs. Always verify the torque setting before beginning a fastening sequence.
