Proto J72212 Deep Impact Socket Set 11 Pc 3/8 in Drive

Product Description

The PROTO J72212 is an 11-piece metric deep impact socket set built for professional trade use in mechanical, HVAC, and industrial service work. The set covers a 3/8 inch drive and includes sockets ranging from 7 mm to 17 mm in a 6-point configuration. The 6-point design reduces fastener rounding under high-torque impact conditions, making it a reliable choice for techs working on equipment panels, compressor mounts, condenser frames, and similar assemblies. The full set ships on a clip rail with a 9-inch socket bar included, keeping sockets organized and accessible at the job site. Total set weight is 2.47 pounds.

This set is suited for residential and commercial HVAC installation and service, plumbing rough-in, and general mechanical work where metric fasteners are standard. The deep socket profile accommodates threaded studs and longer bolt extensions common in equipment mounting applications. The clip rail storage format is practical for tool bags and service vans. Technicians who work on imported equipment or hydronic heating systems will find the 7 mm through 17 mm range covers the most common metric fastener sizes encountered in the field.
