Proto J6063C Micrometer Torque Wrench 3/8 in Drive

Product Description

The PROTO J6063C is a micrometer-style torque wrench built for precise fastener torque application in mechanical, HVAC, plumbing, and electrical service work. It uses a 3/8 inch drive and measures torque in inch-pounds, with a working range of 40 to 200 in-lb and a graduation of 1 in-lb per increment. The fixed head design keeps the drive orientation consistent during use. Overall length is 11-45/64 inches, giving the technician enough leverage for controlled torque delivery without excessive bulk. At 2.65 pounds, it is light enough for extended use in tight equipment bays or rooftop units.

This wrench is suited for residential and light commercial service applications where inch-pound torque accuracy is required. Typical use cases include tightening flare fittings, electrical panel hardware, condensate pan fasteners, motor mounting bolts, and similar small-to-mid-range fastener work. HVAC technicians, plumbers, and electricians reaching for a 3/8 inch drive tool will find the 40-200 in-lb range covers a wide variety of service calls on mechanical equipment.

Key Features

• 3/8 inch drive fits standard sockets for broad fastener coverage
• Torque range of 40 to 200 in-lb with 1 in-lb graduation for precise settings
• Micrometer-style adjustment dial allows repeatable, locked-in torque settings
• Fixed head design maintains consistent drive angle during torque application
• Compact 11-45/64 inch overall length suits confined service spaces
• Lightweight at 2.65 pounds for reduced fatigue during extended service work

Compatibility

Designed as a general-purpose micrometer torque wrench compatible with standard 3/8 inch drive sockets used across HVAC, plumbing, electrical, and mechanical service applications.

Installation Notes

Torque wrenches should be operated by qualified technicians familiar with the fastener specifications for the equipment being serviced. Always set the wrench to the manufacturer-specified torque value before beginning work and store the wrench at its minimum torque setting when not in use to preserve the internal spring mechanism. Do not use this wrench as a breaker bar or for loosening fasteners, as this can damage the internal mechanism and compromise calibration accuracy. Follow applicable codes and equipment service manuals for required torque values.
