Proto J5529M 29mm 12-point 3/4 Drive Hand Socket

Product Description

The PROTO J5529M is a 29 mm, 12-point hand socket designed for 3/4 inch drive ratchets, breaker bars, and torque wrenches. Constructed from alloy steel with a chrome-plated finish, it delivers the corrosion resistance and surface durability demanded in professional shop and field environments. The standard-length profile measures 2-7/32 inches overall, making it suitable for most accessible fastener applications. This socket meets ASME B107.110-2012 requirements, confirming dimensional and performance compliance. It is intended for use by mechanics, millwrights, and maintenance technicians working on heavy equipment, industrial machinery, or large-fastener applications where a 3/4 inch drive is required.

The J5529M fits standard 3/4 inch drive tool setups and is appropriate for both residential and commercial maintenance environments. Typical use cases include heavy equipment service, fleet maintenance, industrial assembly, and structural fastener work where a 29 mm hex fastener is involved. The 12-point geometry allows engagement at 30-degree increments, which is useful in tighter swing-arc situations. This socket is not tether-capable and is intended for conventional, non-dropped-object-control environments.

Key Features

• 29 mm socket size fits large hex fasteners common in heavy equipment and industrial applications
• 12-point design provides 30-degree engagement increments for improved access in restricted spaces
• 3/4 inch drive compatible with standard heavy-duty ratchets, breaker bars, and torque wrenches
• Alloy steel construction provides high tensile and impact strength
• Chrome-plated finish resists corrosion and simplifies cleaning
• Meets ASME B107.110-2012 dimensional and performance standards

Compatibility

Designed as a standard OEM-style replacement or addition to any 3/4 inch drive hand socket set requiring a 29 mm 12-point socket.

Installation Notes

Installation and removal of fasteners should be performed by qualified mechanics or maintenance technicians familiar with 3/4 inch drive tooling. Verify the socket is fully seated on the fastener before applying torque to prevent rounding. This socket is not rated for tethered or dropped-object-prevention applications and should not be used in elevated work zones where tool drops are a hazard. Inspect the socket for cracks or wear before each use and retire any damaged tooling immediately.
