Proto J5548 1-1/2 Inch 12-point 3/4 Drive Hand Socket

Product Description

The PROTO J5548 is a 1-1/2 inch, 12-point hand socket designed for heavy-duty fastener work in professional trade and industrial environments. Built to a standard length profile, it accepts a 3/4 inch square drive and features a chrome-plated finish for corrosion resistance and easy cleaning. The 12-point configuration provides more engagement positions around the fastener head, reducing ratchet swing arc in tight spaces. This socket is suited for licensed mechanics, millwrights, pipefitters, and maintenance technicians who regularly work with large-hex fasteners on heavy equipment, flanges, and structural assemblies.

The J5548 is appropriate for stationary and field service applications where a 1-1/2 inch hex fastener must be driven or broken loose with a 3/4 inch drive ratchet, breaker bar, or torque wrench. Standard length makes it a straightforward fit for open-access fasteners without the clearance constraints that require deep-well or extension setups. It is commonly used in industrial plant maintenance, heavy equipment repair, and commercial mechanical service work.

Key Features

• 1-1/2 inch socket size for large-hex fastener applications
• 3/4 inch square drive for high-torque ratchets and breaker bars
• 12-point design increases positional flexibility around fastener flats
• Standard length profile for straightforward open-access installations
• Chrome-plated finish resists corrosion and simplifies surface cleaning

Compatibility

Designed as an OEM-style hand socket compatible with 3/4 inch drive ratchets, torque wrenches, and breaker bars used in industrial and heavy mechanical service applications.

Installation Notes

This socket is installed and removed by hand tool professionals including millwrights, pipefitters, and heavy equipment mechanics. Confirm the drive tool and socket are fully seated before applying torque to prevent rounding or ejection. Inspect the socket for cracks or wear before use on high-torque applications. Follow applicable workplace safety standards when working on pressurized or energized assemblies.
