Proto J72104 Impact Socket Set 13 Pc 3/4 in Drive

Product Description

The PROTO J72104 is a 13-piece impact-rated standard socket set built for heavy-duty fastening applications in the trades. The set uses a 3/4 inch drive and covers sizes from 3/4 inch through 1-1/2 inch in 1/16-inch increments. Each socket is 12-point and manufactured from steel to handle the torque output of pneumatic and electric impact wrenches. This set is suited for HVAC equipment installation, structural mechanical work, and any application where large-fastener torque is required. A licensed mechanic, HVAC installer, or industrial technician is the typical end user.

This socket set is used wherever 3/4 inch drive impact tooling is required, including commercial HVAC equipment installation, chiller and rooftop unit mounting, large pump and motor applications, and heavy mechanical assembly. The 13 included sizes eliminate the need to source individual sockets across the most common large-fastener range. The 12-point design allows for more contact angles when positioning the socket on a fastener head.

Installation Notes

Impact sockets are intended for use with impact wrenches and should not be substituted with chrome hand-tool sockets on impact drivers. Inspect each socket for cracks or deformation before use, particularly after high-torque applications. Always ensure the drive pin and retaining ring or clip are fully engaged before applying torque. Use appropriate personal protective equipment when operating impact tooling in a trade environment.
