Proto J72118 Deep Impact Socket Set 25 Pc 3/8 in Drive

Product Description

The PROTO J72118 is a 25-piece deep impact socket set built for professional trade use in demanding fastener applications. Driven by a 3/8 inch drive, the set covers both inch and metric sizes, ranging from 15/16 inch (7 mm) to 1 inch (19 mm). Each socket features a 6-point design that maximizes contact on fastener flats and reduces rounding under high-torque conditions. Sockets are manufactured from steel with a polished finish and are engineered to handle the rotational force of impact tools. HVAC technicians, plumbers, electricians, and general trade professionals will find this set a reliable fit for equipment fastening tasks on the job site or in the shop.

This set is suited for residential and commercial service work where both inch and metric fasteners are encountered. The deep profile accommodates extended bolts, studs, and recessed fasteners that standard-depth sockets cannot reach. Packaged in a cardboard box, the set ships as a single unit and is organized for easy identification of each size. Typical applications include mechanical equipment installation, panel work, pipe fitting hardware, and general service where impact-rated sockets are required by the task or preferred for speed.

Installation Notes

Impact sockets should only be used with impact-rated drive tools. Inspect sockets for cracks or deformation before each use and remove any damaged sockets from service. Always ensure the socket is fully seated on the fastener and the retaining pin or ring is engaged before applying torque. Power down or de-energize equipment before servicing fasteners on electrical or mechanical systems.
