Proto J6012E Torque Wrench 3/8 in Drive 5-99 Ft/lb

Product Description

The PROTO J6012E is a 3/8 inch drive torque wrench designed for precise fastener tightening in mechanical, HVAC, plumbing, and general trade applications. It delivers a torque range of 5 to 99 ft/lb with a 0.1 ft/lb graduation, giving technicians fine control across a wide working range. The ratchet head allows fastener engagement without resetting the wrench position on each stroke, saving time in confined or repetitive installations. At 4.641 pounds, it carries the mass expected of a full-metal torque tool built for daily shop and field use. Licensed tradespeople and maintenance technicians are the primary users.

This wrench fits standard 3/8 inch drive sockets and is suited for tasks requiring controlled torque on mechanical connections, equipment mounting hardware, valve packing nuts, and similar fasteners encountered in HVAC, refrigeration, plumbing, and light industrial service work. Its foot-pound measurement scale aligns with specifications commonly published in equipment service manuals used across these trades. The 0.1 ft/lb graduation supports applications where overtightening would damage threads, gaskets, or brittle fittings.

Compatibility

Designed for use with standard 3/8 inch drive sockets and accessories across general trade, mechanical service, and maintenance applications.

Installation Notes

This tool is used by licensed HVAC technicians, plumbers, pipefitters, and mechanical contractors. Always set the torque value before applying the wrench to the fastener and release tension on the mechanism by backing the adjustment to the lowest setting after use to preserve calibration. Consult the applicable equipment service manual or code reference for required fastener torque values before use. Do not use extension bars or cheater pipes on the handle, as this alters the applied torque and can damage the internal mechanism.
