Proto J5564 Hand Socket 2 in 12-point 3/4 Drive

Product Description

The PROTO J5564 is a 2-inch, 12-point hand socket designed for heavy-duty fastener work on large hex fasteners. Built from alloy steel with a chrome-plated finish, it seats on a 3/4-inch drive and delivers the torque capacity needed for industrial, fleet, and mechanical service applications. The 12-point configuration allows engagement at 30-degree increments, giving technicians more swing arc in tight quarters. Overall length is standard at approximately 3-7/64 inches. The socket meets ASME B107.110-2012 requirements, confirming dimensional and performance conformance to recognized industry standards. Mechanics, millwrights, and heavy equipment technicians will find this socket well suited for high-torque fastener removal and installation.

The J5564 is used in applications requiring a large-bore socket on a 3/4-inch drive ratchet, breaker bar, or torque wrench. Typical use cases include commercial vehicle drivetrain service, industrial equipment maintenance, and structural fastener work where 2-inch hex fasteners are common. The standard-length profile fits most open-access fastener positions without the added height of a deep socket. This socket is not tether capable and is intended for conventional hand-tool use in shop and field environments.

Key Features

• 2-inch socket size for large hex fasteners common in heavy equipment and fleet service
• 12-point design allows engagement every 30 degrees for improved access in restricted swing areas
• 3/4-inch drive compatible with standard ratchets, breaker bars, and torque wrenches
• Alloy steel construction provides high strength and resistance to deformation under load
• Chrome-plated finish resists corrosion and simplifies cleaning
• Meets ASME B107.110-2012 dimensional and performance standard

Compatibility

Designed as a standard OEM-style 3/4-inch drive hand socket for use with compatible 3/4-inch drive hand tools including ratchets, breaker bars, extensions, and torque wrenches accepting 2-inch, 12-point sockets.

Installation Notes

Installed by mechanics, millwrights, and heavy equipment technicians as part of standard hand-tool socket sets. Ensure the drive square is fully seated before applying torque to prevent rounding the drive recess or damaging the fastener. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. This socket is not rated for impact tool use unless specifically marked for that application.
