Proto J5572 Hand Socket 2-1/4 in 12-point 3/4 Drive

Product Description

The PROTO J5572 is a 12-point hand socket designed for heavy-duty fastener work in industrial, mechanical, and trade service environments. Built from alloy steel with a chrome-plated finish, it accepts a 3/4 inch drive and fits 2-1/4 inch fasteners. The standard-length profile measures 3-13/32 inches overall, giving technicians adequate reach without excessive bulk. Weighing 3.14 pounds, the J5572 meets ASME B107.110-2012 dimensional and performance standards. Mechanics, millwrights, and heavy equipment technicians rely on this socket for applications where precision fit and durability under high torque are required.

This socket is suited for use in industrial maintenance, fleet service, and heavy equipment repair where 2-1/4 inch fasteners are common. The 12-point configuration engages hex and double-hex fasteners, offering more contact positions than a 6-point design for ease of placement in tight or awkward access situations. The 3/4 inch drive squares up with standard 3/4 inch drive ratchets, breaker bars, and torque wrenches common in professional shops and field service rigs.

Key Features

• 2-1/4 inch socket size for large-fastener applications in industrial and heavy equipment service
• 12-point design allows more positioning options during fastener engagement
• 3/4 inch drive compatible with standard heavy-duty drive tools
• Alloy steel construction provides strength under high torque loads
• Chrome-plated finish resists corrosion and simplifies cleaning
• Meets ASME B107.110-2012 standards for hand socket dimensions and performance

Compatibility

Designed as a standard 3/4 inch drive, 2-1/4 inch hand socket compatible with 3/4 inch drive ratchets, breaker bars, torque wrenches, and impact-rated extensions used in professional mechanical and industrial service settings.

Installation Notes

Installation and removal of large fasteners using this socket should be performed by qualified mechanics or millwrights familiar with the torque requirements of the specific application. Ensure the drive tool and socket are fully seated before applying load to prevent rounding of the fastener or socket slippage. De-energize, depressurize, or otherwise render safe any equipment before servicing fastened components. This socket is not tether capable and should be secured appropriately when working at elevation or in overhead applications.
