Proto J6061C Micrometer Fixed Head Torque Wrench

Product Description

The PROTO J6061C is a micrometer-style torque wrench with a fixed head, designed for precise fastener torque application in mechanical, HVAC, and industrial service work. It covers a torque range of 5 Nm to 339 Nm (up to 200 in/lb), with a fine graduation of 0.11 Nm (1 in/lb), allowing technicians to hit tight torque tolerances on bolts, fittings, and equipment fasteners. The overall length is approximately 11.703 inches. The fixed head design keeps the drive orientation consistent during use, reducing the chance of slippage or ratchet-related inaccuracy. Weighing 2.56 pounds, it is a solid tool built for regular shop and field use by service professionals who need repeatable torque results.

This torque wrench is suited for residential and light commercial service applications where accurate fastener torque is required. Typical install scenarios include tightening compressor mounting hardware, refrigerant line fittings, electrical panel fasteners, and mechanical equipment assemblies. The broad Nm range makes it practical across a variety of fastener sizes encountered in HVAC, plumbing, and general mechanical work. Licensed technicians and journeymen mechanics who follow manufacturer torque specifications will find the fine graduation useful for confirming precise values during equipment installation or maintenance.

Installation Notes

This tool is used by licensed HVAC technicians, plumbers, electricians, and mechanical service professionals for fastener torque work during equipment installation and maintenance. Power down or de-energize equipment and shut off all relevant service valves before working on connected assemblies. Apply torque smoothly and stop at the click or dial indicator to avoid overtightening. Store the wrench at its lowest torque setting after use to preserve calibration of the internal spring mechanism.
