Proto J78413MP Impact Socket 3/8 in Drive 13mm

Product Description

The PROTO J78413MP is a 6-point impact socket designed for use with 3/8 inch drive impact wrenches and rattle guns. Built from alloy steel, this socket measures 13mm across the hex drive opening and has an overall length of 2-19/32 inches. The 6-point contact geometry reduces fastener rounding under high-torque impact loads, making it the preferred choice over 12-point sockets for stubborn or corroded fasteners. Meets ASME B107.2 specification. Mechanics, technicians, and trade professionals across automotive, HVAC, plumbing, and electrical work rely on impact-rated sockets like this one to handle pneumatic and cordless impact tool output without cracking or deforming.

This socket is suited for professional shop and field applications where a 3/8 inch drive impact tool is the platform of choice. Common use cases include equipment service, panel fastening, mechanical assembly, and general maintenance tasks requiring a 13mm hex fastener. Its universal style and compact alloy steel construction make it adaptable across a wide range of trade environments, from service vans to shop benches.

Compatibility

Designed as a standard OEM-style impact socket for use with 3/8 inch drive impact wrenches, extensions, and adapters across professional and trade applications requiring a 13mm hex fastener socket.

Installation Notes

Impact sockets must only be used with impact-rated drive tools and accessories. Never use standard chrome sockets with impact wrenches, as they are not rated for the shock loads involved. Inspect the socket for cracks or deformation before each use and replace if damage is found. No additional hand tools or special codes apply, but always confirm the drive size and socket size match the fastener and tool before applying torque.
