Proto J74419MP Impact Socket 1/2 in Drive 19mm 6-pt

Product Description

The PROTO J74419MP is a 6-point impact socket designed for heavy-duty fastening and removal applications. Built from alloy steel, it accepts a 1/2 inch drive and fits 19mm hex fasteners. The 6-point contact geometry reduces rounding on worn or tight fasteners, making it a reliable choice for impact wrench use in automotive, mechanical, and industrial service work. Overall length is 2-11/16 inches. This socket meets ASME B107.2 standards and is sold as a single unit.

This socket is suited for professional use in automotive repair, fleet maintenance, equipment service, and general mechanical trade applications. The 1/2 inch drive size pairs with standard impact wrenches and manual ratchets used daily in shop and field environments. The 19mm size is a common fastener dimension across a wide range of vehicles and industrial equipment, making this a frequently reached-for socket in any professional socket set.

Installation Notes

Install and remove with power off or vehicle disabled and secured on stable stands before use. Inspect the socket for cracks or deformation before each use — do not use damaged sockets with impact tools. Use only impact-rated sockets with pneumatic or electric impact wrenches; standard chrome sockets are not designed for impact use and can fracture.
