Proto J74274P 1/2 in Drive 7/16 in 6-point Impact Socket

Product Description

The PROTO J74274P is a 6-point impact socket designed for heavy-duty fastening and removal applications in trade and industrial environments. Built from alloy steel, it accepts a 1/2 inch drive and fits 7/16 inch hex fasteners. The universal style and 6-point geometry provide solid engagement on standard hex hardware, reducing the risk of fastener rounding under high torque impact loads. With an overall length of 2-19/32 inches, it fits into typical impact wrench configurations used by HVAC technicians, plumbers, electricians, and mechanical contractors on the job.

This socket is suited for residential and commercial service work where a 1/2 inch drive impact wrench is the tool of choice. It handles the fastener sizes common in equipment mounting, electrical panel work, pipe flange assembly, and general mechanical installation. The 6-point contact pattern is preferred over 12-point designs when working with fasteners that may be corroded or heavily torqued, as it distributes load more evenly across the flat faces of the hex.

Key Features

Installation Notes

This socket is installed by licensed trades and qualified mechanics using 1/2 inch drive impact tools. Always ensure the socket is fully seated on the drive anvil and the fastener before applying torque. Inspect the socket for cracks or deformation before each use and replace if damaged. Do not use impact sockets on manual torque wrenches without confirming tool compatibility.
