Proto J74142 Impact Socket Set 7 Pc 1/2 in Drive

Product Description

The PROTO J74142 is a 7-piece impact socket set built for 1/2 inch drive impact wrenches and air tools. The set covers seven sizes from 7/16 inch to 13/16 inch, all in a 6-point configuration that grips fastener flats firmly and reduces the risk of rounding. Each socket features a Torque Plus design and a black oxide finish for corrosion resistance and durability in demanding shop and field environments. Licensed mechanics, maintenance techs, and heavy equipment service professionals will find this set sized for the most common mid-range fasteners encountered in mechanical and structural work.

This set is suited for automotive service, industrial maintenance, and general mechanical repair where a 1/2 inch drive impact tool is the standard. The seven individual sizes span 7/16 inch, 1/2 inch, 9/16 inch, 5/8 inch, 11/16 inch, 3/4 inch, and 13/16 inch, covering the fastener range found on suspension components, drivetrain hardware, equipment frames, and structural assemblies. The set ships with a socket bar and seven socket clips to keep sockets organized and accessible at the work site.

Installation Notes

Impact sockets are designed exclusively for use with impact tools and should not be substituted with standard chrome sockets in high-torque applications. Inspect each socket for cracks or deformation before use, and never use damaged sockets. Power down or disconnect air and electric impact tools before changing sockets. Follow applicable shop safety procedures and equipment manufacturer guidelines when servicing fastened assemblies.
