Product Description

The PROTO J52230-1A is a 34-piece deep and standard socket set built for professional trade use across HVAC, plumbing, electrical, and general mechanical service work. The set is driven by a 3/8 inch drive and covers both inch and metric sizes, ranging from 5/16 inch to 7/8 inch in SAE and 8 mm to 19 mm in metric. All sockets feature a 12-point design and a chrome finish. The kit ships complete with a 3/8 inch drive pear head ratchet, a universal joint, extension bars at 3 and 6 inches, and a socket bar with clips. At 17.23 pounds, this is a dense, full-coverage set intended for working technicians who need one box for a wide range of fastener sizes.

This set is suited for residential and light commercial service environments where both inch and metric fasteners are common. HVAC technicians will find the metric and SAE dual coverage useful when working on mixed-origin equipment. Electricians and plumbers will benefit from the deep socket selection when dealing with recessed hardware, conduit fittings, and fixture connections. The included ratchet, universal joint, and extensions make this a self-contained service kit that travels well in a van or truck toolbox.

Installation Notes

Socket sets of this type are used by licensed tradespeople across multiple disciplines and require no installation in the traditional sense, but safe handling practices apply. Always match the drive size rating of accessories before use, and do not use impact-rated tools with chrome sockets not rated for impact service. Store in the provided tool box to prevent corrosion and keep sockets organized by size.
