Proto J6181F Dial Torque Wrench 3/8 in Drive 600 In/lb

Product Description

The PROTO J6181F is a dial torque wrench designed for precision fastener torque application and verification in mechanical, HVAC, plumbing, and electrical service work. Built on a 3/8 inch drive, it reads torque in inch-pounds via a fixed dial head, allowing the technician to monitor applied torque in real time throughout the fastening stroke. Maximum torque capacity is 600 inch-pounds, with dial graduations of 10 in/lb for consistent, readable increments. Overall length is 10 inches. At 1.97 pounds, it is compact enough for confined service bays and equipment rooms.

The J6181F is suited for residential and light commercial service applications where inch-pound torque control is required. Typical uses include tightening fasteners on HVAC access panels, compressor mounting hardware, electrical enclosure covers, and plumbing fixture assemblies. The 3/8 inch drive accepts standard 3/8 inch drive sockets and adapters, making it compatible with commonly stocked socket sets in field service kits. The dial readout allows continuous torque monitoring without a preset breakaway mechanism, which is useful when a specific torque range must be confirmed rather than a single threshold.

Key Features

• Dial-type readout provides real-time torque reading throughout the fastening stroke
• Maximum torque capacity of 600 inch-pounds covers a wide range of light to medium fastener applications
• 10 in/lb dial graduation allows precise, repeatable torque application
• 3/8 inch drive accepts standard sockets and adapters already in most service kits
• Fixed head design simplifies use and reduces mechanical complexity
• Compact 10 inch overall length suits confined work areas common in equipment service

Compatibility

Designed for use with standard 3/8 inch drive sockets and accessories. Suitable for general mechanical fastening tasks requiring inch-pound torque measurement in HVAC, plumbing, electrical, and related trade service applications.

Installation Notes

The J6181F should be used by qualified trade technicians familiar with torque specification requirements for the fasteners being serviced. Always de-energize electrical equipment and isolate systems before servicing fasteners on live components. Store the wrench at or below its minimum scale reading when not in use to preserve dial mechanism calibration. Do not use as a breaker bar or apply force beyond the stated maximum torque capacity.
