Proto J7316MHT Impact Socket 1/2 in Drive 16mm

Product Description

The PROTO J7316MHT is a 16mm, 6-point impact socket designed for use with 1/2 inch drive impact wrenches and rattle guns. Built from alloy steel, it is engineered to absorb the rotational shock loads that destroy standard chrome hand-sockets. The thin-wall design allows access in tight or recessed fastener locations where a standard-wall socket would not fit. Overall length is 3.25 inches. This socket is used by mechanics, millwrights, fleet technicians, and industrial maintenance pros who run 1/2 inch drive impact tools daily.

The J7316MHT fits typical under-hood, drivetrain, and general mechanical fastening applications where 16mm hex fasteners appear. The thin-wall profile makes it well suited for fasteners seated in counterbores or surrounded by flanges. It is sold individually and is appropriate for both shop and field use. Technicians working on automotive, light truck, and light industrial equipment will find the 6-point engagement reduces fastener rounding compared to 12-point designs, particularly when removing corroded or over-torqued hardware.

Key Features

• 1/2 inch drive hex interface compatible with standard 1/2 inch drive impact wrenches
• 16mm 6-point socket for maximum contact on hex fasteners and reduced rounding risk
• Thin-wall construction allows access in tight or counterbored fastener locations
• Alloy steel construction rated for impact tool use
• 3.25 inch overall length suitable for standard-reach applications

Compatibility

Designed as an OEM-style impact socket for use with standard 1/2 inch drive impact wrenches and extensions. Compatible with any 1/2 inch drive impact tool using a standard square drive interface.

Installation Notes

Impact sockets should only be used with impact tools, not with torque wrenches or breaker bars, as the shock loads differ from hand-tool use. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Always ensure the socket is fully seated on the fastener before applying drive force to prevent slippage and fastener damage.
