Proto J52304 Standard Socket Set 13 Pc 3/8 in Drive

Product Description

The PROTO J52304 is a 13-piece standard socket set built on a 3/8 inch drive. It covers inch sizes from 1/4 inch through 1 inch, making it a practical general-purpose set for service technicians working on mechanical systems, equipment, and hardware. All 13 sockets feature a 12-point design, which provides good contact on fastener flats and allows ratcheting at tighter angles in confined spaces. The set meets ASME B107.1, the recognized standard for hand socket tools. This set suits HVAC service, plumbing rough-in, electrical panel work, and general mechanical maintenance where a versatile mid-drive socket set is needed on the job.

This socket set is suited for residential and light commercial trade applications. A 3/8 inch drive balances torque capacity with maneuverability, making it appropriate for fasteners commonly encountered on air handlers, condensing units, plumbing fixtures, electrical enclosures, and mechanical equipment. The full range from 1/4 inch to 1 inch covers the majority of standard fastener sizes found in trade work. A 13 inch socket bar and socket clips are included to keep the set organized on the job.

Installation Notes

This set is intended for use by licensed tradespeople and qualified mechanics performing fastener-related service tasks.

Do not use hand sockets with impact drivers unless the socket is rated for impact use.
