Proto J77519MP Impact Socket 3/8 in Drive 19mm

Product Description

The PROTO J77519MP is a 12-point impact socket designed for use with 3/8 inch drive impact wrenches and ratchets. Built from alloy steel, it delivers the torsional strength needed to handle fastener removal and installation under impact torque without cracking or deforming. The socket measures 2-3/32 inches overall length and fits a 19mm fastener. Its 12-point geometry allows engagement from multiple positions, which speeds up work in confined spaces. This socket is suited for automotive, mechanical, and light industrial applications where an impact-rated tool is required.

This socket is used in automotive repair, fleet maintenance, and general mechanical work where 19mm fasteners are common. The 3/8 inch drive size positions it as a mid-range socket appropriate for passenger vehicles and light trucks. It meets ASME B107.2 standards, which specify dimensional and performance requirements for impact sockets. Licensed tradespeople and experienced DIYers working on suspension, wheel, and drivetrain components will find this socket a direct fit for standard impact tools.

Installation Notes

Always verify the drive tool is rated for impact use before attaching an impact socket. Ensure the socket seats fully on the fastener before applying torque to avoid rounding. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Always wear appropriate eye protection when operating impact tools.
