Proto J5530HL Deep Hand Socket 15/16 in 3/4 Drive 6-point

Product Description

The PROTO J5530HL is a deep hand socket designed for heavy-duty hand-tool applications requiring extended reach. Built from alloy steel with a chrome-plated finish, this socket features a 3/4-inch drive and a 15/16-inch socket size across a 6-point contact pattern. The 6-point design grips fastener flats rather than corners, reducing the risk of rounding under high torque. At 3.5 inches overall length, it provides the depth needed for recessed or stud-mounted fasteners. Meets ASME B107.110-2012 standards. Intended for use by mechanics, millwrights, pipefitters, and industrial technicians working with larger fasteners and heavy equipment.

This socket is suited for industrial maintenance, construction, and mechanical assembly work where fasteners are deeply recessed or where a standard-length socket cannot achieve full engagement. The 3/4-inch drive makes it appropriate for use with heavy-duty ratchets, breaker bars, and torque wrenches common in fleet maintenance, structural steel work, and equipment overhaul environments. It is not tether capable and is intended for standard stationary or bench-level fastener work.

Key Features

• 15/16-inch socket size fits common large fastener applications
• 3/4-inch drive compatible with heavy-duty hand tool sets
• 6-point contact pattern reduces fastener rounding under high torque
• Deep length at 3.5 inches for recessed fastener access
• Alloy steel construction with chrome-plated finish for corrosion resistance
• Meets ASME B107.110-2012 standard for socket dimensions and performance

Compatibility

Designed for use with standard 3/4-inch drive ratchets, breaker bars, and torque wrenches. Compatible with 15/16-inch hex fasteners in industrial, mechanical, and construction applications.

Installation Notes

This socket is installed and removed by hand-tool technicians and does not require power tools. Ensure the drive tool is rated for the torque demands of the application before use. Inspect the socket for cracks or wear before each use, particularly in high-cycle industrial environments. This socket is not tether capable and should not be used in elevated work areas where drop hazards are a concern.
