Proto J5542HL Deep Hand Socket 1-5/16 in 3/4 Drive 6-point

Product Description

The PROTO J5542HL is a deep hand socket designed for 3/4-inch drive ratchets and breaker bars. Built from alloy steel with a satin finish, it handles a 1-5/16-inch fastener size across a 6-point contact geometry. The 6-point design distributes torque evenly across the flats of a nut or bolt head, reducing rounding under heavy load. At 3.5 inches overall length, the deep profile provides clearance for long bolt shanks, studs, and recessed fasteners that a standard-length socket cannot reach. This socket meets ASME B107.110-2012 standards and is suited for heavy mechanical, industrial, and automotive service work performed by professional trades.

The J5542HL is appropriate for use in automotive repair, truck fleet maintenance, industrial equipment service, and construction trades where large-diameter fasteners and extended reach are common requirements. The 3/4-inch drive sizing makes it a natural fit for high-torque applications involving suspension components, heavy machinery, structural bolting, and similar work where smaller drive sizes are undersized for the job. It is not tether capable and is intended for standard hand tool use in controlled shop or field environments.

Key Features

• 6-point contact geometry reduces fastener rounding under high torque loads
• Deep length profile at 3.5 inches overall accommodates long studs and recessed fasteners
• Alloy steel construction provides strength suitable for 3/4-inch drive torque levels
• Satin finish reduces glare and offers moderate corrosion resistance
• Meets ASME B107.110-2012 standards for hand socket tools
• Single-piece packaging with no minimum order beyond one unit

Compatibility

Designed as an OEM-style deep hand socket for use with standard 3/4-inch drive ratchets, breaker bars, and extensions in professional and industrial service applications.

Installation Notes

Installed by mechanics, millwrights, ironworkers, and other trades requiring 3/4-inch drive tooling for large fasteners. Ensure the socket is fully seated on the fastener before applying torque to prevent slippage or fastener damage. Inspect the socket for cracks or wear before each use, particularly in high-cycle or impact-adjacent applications. This socket is rated for hand tool use only and is not designated as tether capable for elevated work environments.
