Proto J5780 2-1/2 Inch 12-point Hand Socket

Product Description

The PROTO J5780 is a 12-point hand socket designed for professional-grade mechanical and industrial work. Built from alloy steel with a satin finish, it accepts a 1-inch drive and fits a 2-1/2-inch fastener. The overall length is 4.125 inches, making it suitable for applications where reach and torque transfer matter. This socket meets ASME B107.110-2012 standards, confirming dimensional and performance compliance for trade and industrial use. It is a standard non-tethered tool intended for general fastening and removal tasks in heavy equipment, infrastructure, and industrial maintenance environments.

The J5780 is used in maintenance, repair, and overhaul settings where large-diameter fasteners are common. Typical applications include heavy equipment servicing, structural assembly, and industrial plant maintenance. The 1-inch drive interface pairs with heavy-duty ratchets, breaker bars, and torque wrenches suited for high-torque fastener work. Licensed mechanics, pipefitters, millwrights, and industrial maintenance technicians are the primary users of this socket size and drive class.

Key Features

• 12-point socket geometry allows engagement at multiple fastener positions, useful in tight working angles
• 1-inch drive size for high-torque applications with compatible drive tools
• Alloy steel construction provides durability under heavy load
• Satin finish reduces glare and provides light corrosion resistance
• Meets ASME B107.110-2012 dimensional and performance standard
• 4.125-inch overall length accommodates moderate fastener depth reach

Compatibility

Designed for use with 1-inch drive ratchets, breaker bars, and torque wrenches. Fits 2-1/2-inch fasteners in heavy-duty mechanical and industrial applications.

Installation Notes

This socket is installed and used by qualified mechanics, millwrights, and industrial maintenance technicians. Confirm the drive tool is rated to match the torque demands of the fastener application before use. Inspect the socket for cracks or wear before each use and remove from service if damage is found. This socket is not tether capable and should not be used in elevated work environments requiring tool retention systems.
