Proto J47122S 22-piece Sae Socket Set 3/8 Drive

Product Description

The PROTO J47122S is a 22-piece SAE socket set built around a 3/8-inch drive and covering a size range from 3/16 inch to 1 inch. All sockets are 6-point, which delivers better torque transfer and reduces the risk of rounding fastener corners under load. The set ships in a metal case that keeps sockets organized and protected on a job site or in a service van. It is suited for HVAC technicians, plumbers, electricians, and general trade professionals who need a compact, full-range SAE socket assortment for equipment service, panel work, and mechanical assembly tasks.

The J47122S covers residential and light commercial service applications where SAE fasteners are standard. The set includes both 1/4-inch and 3/8-inch drive sockets, a 1/4-inch socket driver, a 3/8-inch female to 1/4-inch male adapter, and two extensions for reaching recessed fasteners. This makes it a practical choice for technicians working inside equipment cabinets, electrical enclosures, and mechanical rooms where access is limited and multiple drive sizes are needed in a single kit.

Installation Notes

Socket sets are used by licensed tradespeople across HVAC, plumbing, electrical, and mechanical disciplines. Always de-energize equipment and shut off gas or water supply before beginning fastener work on live systems. Inspect sockets for cracks or wear before use, and do not use impact-rated ratchets with non-impact-rated sockets. Store the set in the provided metal case to prevent loss and maintain socket identification.
