Proto J6342 Digital Torque Wrench 1/4 in Drive 100 In-lb

Product Description

The PROTO J6342 is a digital torque wrench with a 1/4 inch fixed-head drive, designed for precise fastener torque application in mechanical, HVAC, plumbing, and electrical service work. It measures torque in inch-pounds with a maximum capacity of 100 in-lb and a minimum of 0.83 ft-lb, making it well-suited for light to medium fastening tasks where accuracy is critical. The digital readout provides a graduation of 0.10 in-lb, giving technicians repeatable, verifiable torque readings without relying on a click or beam mechanism. The wrench weighs 2.57 pounds and measures 11 inches overall, making it compact enough for tight service environments.

The J6342 is suited for residential and light commercial service applications where calibrated torque is required on small fasteners. HVAC technicians, refrigeration mechanics, plumbers, and electricians use digital torque wrenches when manufacturer specifications or code compliance demand documented torque values — such as on electrical panel connections, equipment mounting bolts, and flare fittings. The 1/4 inch drive accepts standard sockets, keeping tooling interchangeable with existing sets.

Compatibility

Designed as an OEM-style service tool for trade professionals requiring calibrated torque application on 1/4 inch drive fasteners across HVAC, plumbing, and electrical service applications.

Installation Notes

Digital torque wrenches should be stored at a low torque setting or zeroed after use to preserve calibration. Power down or de-energize any equipment before applying torque to electrical connection hardware. Ensure sockets are fully seated on the drive before applying load to avoid slippage and inaccurate readings. Periodic recalibration is recommended per the manufacturer service interval or applicable workplace torque tool standards.
