Proto J54113 19pc 1/2 in Drive Socket Set 3/8-1-1/2 in

Product Description

The PROTO J54113 is a 19-piece standard socket set built around a 1/2 inch drive and covering sizes from 3/8 inch through 1-1/2 inch. Each socket features a 12-point design and a chrome finish. The set is measured in inch sizes, making it suited for standard SAE fastener work across a wide range of bolt and nut sizes. At 7.25 pounds, the set carries enough heft for professional-grade construction while remaining portable. Licensed tradespeople and journeymen mechanics who need a comprehensive mid-to-large drive socket selection in a single kit will find this set covers the most common fastener sizes encountered in HVAC equipment, plumbing rough-in, and general mechanical work.

This socket set is appropriate for residential and commercial service applications where 1/2 inch drive tooling is standard. The 19 individual sizes span from 3/8 inch up to 1-1/2 inch, addressing the broad range of fastener heads found on air handling units, compressor mounting hardware, pipe flanges, and structural mechanical connections. It is equally at home in a service van or a shop setting where technicians require a reliable, complete socket selection without sourcing individual sizes separately.

Compatibility

Designed for use with standard 1/2 inch drive ratchets, extensions, and torque wrenches. Socket sizing is SAE inch only; not intended for metric fastener applications.

Installation Notes

This set is intended for use by qualified tradespeople including HVAC technicians, plumbers, and mechanical contractors. Always ensure the drive tool is rated for the torque being applied before use on structural or pressure-bearing fasteners. Inspect each socket for cracks or deformation before use, and never use impact-rated torque values with chrome hand-tool sockets unless the sockets are rated for impact use. Power down or de-energize any equipment before accessing fasteners on live mechanical or electrical systems.
