Proto J74413MP Impact Socket 1/2 in Drive 13mm

Product Description

The PROTO J74413MP is a 6-point impact socket designed for heavy-duty fastening and removal applications where standard sockets would fail under torque load. Built from alloy steel, it accepts a 1/2 inch square drive and fits a 13mm hex fastener. The overall length is 2-19/32 inches, keeping it compact enough for tight access while maintaining the wall thickness required to handle impact driver and air wrench output. This socket meets ASME B107.2, confirming it is manufactured and tested to recognized industry dimensional and performance standards. Mechanics, industrial maintenance technicians, and field service pros reach for this part when working with metric fasteners in demanding environments.

This socket is suited for automotive, fleet maintenance, HVAC equipment service, and general industrial assembly where 1/2 inch drive impact tools are standard. The 6-point design concentrates force on the flats of the fastener rather than the corners, reducing rounding on corroded or high-torque fasteners. It is appropriate for both stationary shop use and mobile service applications. The universal style designation indicates it is intended as a broadly applicable impact socket rather than a specialized or thin-wall variant.

Key Features

• 6-point socket geometry reduces fastener rounding under high torque
• Alloy steel construction rated for impact tool use
• Meets ASME B107.2 dimensional and performance standard
• 1/2 inch square drive fits standard impact wrenches and ratchets
• Compact 2-19/32 inch overall length for restricted-access fastener work
• Universal style — broad application across automotive and industrial tasks

Compatibility

Designed for use with 1/2 inch drive impact wrenches, air ratchets, and hand ratchets where a 13mm hex socket is required. Compatible with standard 1/2 inch drive detent-pin and hog-ring impact anvil configurations.

Installation Notes

Install and remove using a 1/2 inch drive impact wrench, air tool, or hand ratchet. Ensure the socket is fully seated on the drive anvil and fastener before applying torque to prevent slippage or fastener damage. Do not use impact sockets on torque-sensitive fasteners requiring precision torque values without a calibrated torque wrench. Inspect the socket for cracks or deformation before each use and remove from service if damage is present.
