Proto J6014NMC Micrometer Torque Wrench 70-350 Nm

Product Description

The PROTO J6014NMC is a micrometer-style click-type torque wrench built for precision fastening in trade and industrial applications. It features a 1/2 inch square drive and a ratcheting head, allowing the user to apply torque within a calibrated range of 70 to 350 Newton meters (Nm) with 1 Nm graduations. The adjustable micrometer barrel lets technicians set a precise target torque before applying force, and the ratchet mechanism enables use in tight or repetitive fastening scenarios. At 6.16 pounds and 27-1/8 inches overall length, it is a full-size professional tool suited for mechanical, HVAC, and industrial assembly work.

This wrench is appropriate for any application requiring controlled torque within the 70 to 350 Nm range using a 1/2 inch drive. Common use cases include tightening large fasteners on HVAC compressor mounts, mechanical equipment, commercial refrigeration systems, and structural assemblies. The 1 Nm graduation resolution makes it well-suited for jobs where precise torque values are specified by equipment manufacturers or service manuals. It is typically used by HVAC technicians, millwrights, pipefitters, and mechanical contractors working on mid- to heavy-duty fastener applications.

Key Features

• Micrometer-style adjustment barrel for precise torque setting before each use
• Torque range of 70 to 350 Nm with 1 Nm graduation increments
• 1/2 inch square drive compatible with standard sockets and adapters
• Ratcheting head for efficient use in confined or repetitive fastening scenarios
• 27-1/8 inch overall length provides adequate leverage for mid- to high-torque fastening

Compatibility

Designed for use with standard 1/2 inch drive sockets and accessories. Suitable for any application requiring torque application in the 70 to 350 Nm range.

Installation Notes

This tool is used by licensed mechanics, HVAC technicians, millwrights, and pipefitters for fastener torquing in accordance with equipment manufacturer specifications. Always return the torque setting to the minimum value after use to relieve spring tension and preserve calibration. Verify the wrench calibration periodically per shop or site quality procedures. Do not use as a breaker bar or apply force beyond the maximum rated torque.
