Proto J77513MP Impact Socket 3/8 in Drive 13mm 12-point

Product Description

The PROTO J77513MP is a 3/8 inch drive impact socket designed for use with pneumatic and electric impact wrenches in professional trade and industrial applications. Built from alloy steel, this 13mm, 12-point socket measures 2 inches in overall length and is rated to the ASME B107.2 standard. The 12-point configuration allows engagement from multiple angles, useful in tight access situations. Weighing 0.24 pounds, it is a compact, durable fastener-drive tool suited for automotive, mechanical, and general maintenance work performed by mechanics, millwrights, and service technicians.

This socket is appropriate for use in both shop and field environments where a 13mm fastener size is common. Typical applications include automotive suspension and drivetrain work, equipment assembly, and structural fastener removal and installation. The universal style designation indicates broad fitment across standard 3/8 inch drive impact tooling setups. It is well-suited for residential and commercial maintenance operations where speed and socket durability under high-torque impact loads are required.

Key Features

• 3/8 inch drive compatible with standard impact wrenches and ratchets
• 13mm socket size for metric fastener applications
• 12-point design allows multiple engagement positions in confined spaces
• Alloy steel construction rated for impact use and high-torque applications
• Meets ASME B107.2 specification for hand socket tools
• Compact 2 inch overall length suits tight-clearance installations

Compatibility

Designed as a standard OEM-style replacement and general-use impact socket compatible with 3/8 inch drive impact wrenches, air ratchets, and hand ratchets accepting 3/8 inch drive tooling.

Installation Notes

Installation and use should be performed by qualified mechanics or maintenance technicians familiar with impact tooling. Always ensure the socket is fully seated 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. Do not use impact sockets with standard hand-torque multipliers beyond their rated capacity.
