Proto J74416MP Impact Socket 1/2 in Drive 16mm

Product Description

The PROTO J74416MP is a 6-point impact socket designed for 1/2 inch square drive impact wrenches and rattle guns. It accepts a 16mm hex fastener and is built from alloy steel for the toughness demands of impact use. The overall length is 2-11/16 inches, making it a standard-depth socket suitable for most fastener applications. Technicians in automotive, heavy equipment, and industrial maintenance work reach for this socket when driving or removing 16mm bolts and nuts under high-torque conditions. The 6-point geometry concentrates drive force on the flat faces of the fastener, reducing rounding on stubborn hardware.

This socket is suited for use in automotive shops, fleet maintenance bays, manufacturing facilities, and field service work where a 1/2 inch drive impact tool is standard. It is rated to ASME B107.2, the governing specification for impact sockets and drive tools. The universal style means it fits a broad range of 1/2 inch drive impact wrenches, air or electric, in both professional and industrial service settings.

Compatibility

Designed as an OEM-style replacement and standard fitment for 1/2 inch drive impact socket sets used in automotive and industrial service applications.

Installation Notes

Install and remove using a 1/2 inch drive impact wrench, air ratchet, or breaker bar. Always use impact-rated sockets with impact tools — chrome hand-tool sockets are not rated for impact service and can fracture. Inspect the socket for cracks or deformation before each use and replace if any damage is found. Retain the socket securely on the drive anvil using a retaining ring or hog ring to prevent ejection during operation.
