Proto J7019MHT Impact Socket 3/8 in Drive 19mm 6-pt

Product Description

The PROTO J7019MHT is a 19mm, 6-point impact socket built for 3/8 inch drive impact wrenches and rattle guns. Manufactured from alloy steel, this thin-wall socket is designed to absorb the rotational shock loads generated by pneumatic and cordless impact tools without cracking or deforming. At 2 inches overall length, it fits into tighter spaces than standard-depth sockets while still providing full-face contact on fastener flats. It is suited for production shops, service bays, and field technicians who need a dependable metric impact socket in a common drive size.

This socket is a standard fitment for automotive, HVAC equipment, and light industrial assembly work where 19mm fasteners are encountered. The 3/8 inch drive size is common in light-duty impact tools used by HVAC technicians, plumbers, and general mechanics for equipment mounting hardware, service panel fasteners, and mechanical assembly. The thin-wall profile allows access in recessed or flanged fastener locations that a standard-wall socket cannot reach.

Key Features

• 3/8 inch square drive fits standard 3/8 inch drive impact wrenches and extensions
• 19mm 6-point socket geometry maximizes contact with fastener flats, reducing rounding under load
• Thin-wall construction improves clearance in recessed and tight-access fastener locations
• Alloy steel construction rated for impact tool use — not a chrome hand-tool socket
• 2 inch overall length suits most standard-depth fastener applications

Compatibility

Designed as a standard 3/8 inch drive impact socket compatible with 3/8 inch drive impact wrenches, extensions, and adapters using a standard square drive interface.

Installation Notes

Impact sockets should only be used with impact-rated drive tools and impact-rated extensions — never substitute chrome hand-tool sockets on impact wrenches, as they can shatter under shock loading. Verify the socket is fully seated on the fastener before applying tool torque. Inspect the socket for cracks or deformation periodically, especially in high-cycle production environments.
