Proto J5224MH 24mm 6-point 3/8 Drive Hand Socket

Product Description

The PROTO J5224MH is a 24 mm, 6-point hand socket built for professional mechanics and trade technicians who need reliable fastener engagement under daily shop conditions. Manufactured from alloy steel with a chrome-plated finish, this socket fits a 3/8 inch drive and delivers the wall thickness and geometry needed to seat squarely on hex fasteners without rounding. The 6-point contact pattern distributes torque evenly across fastener flats, reducing the risk of slippage on tight or corroded hardware. Overall length is 33.3 inches at standard length classification, keeping the profile compact for work in confined spaces.

This socket is suited for automotive, fleet, and light industrial maintenance where 24 mm fasteners appear on suspension components, drivetrain hardware, and general mechanical assemblies. It is a standard-length design appropriate for benchtop work, ratchet use, and torque wrench applications in professional shop environments. Licensed mechanics, fleet technicians, and industrial maintenance workers will find it a direct fit for everyday drive-train and chassis service work.

Key Features

• 24 mm socket size with 6-point contact for even torque distribution on hex fasteners
• 3/8 inch drive compatibility with standard ratchets, extensions, and torque wrenches
• Alloy steel construction for durability under high-torque applications
• Chrome-plated finish resists corrosion and simplifies cleaning
• Standard length profile suits confined-space and open-bench applications
• Meets ASME B107.5 standards for hand socket performance and dimensional accuracy
• Lifetime warranty backed by the manufacturer

Compatibility

Designed as an OEM-style hand socket for use with standard 3/8 inch drive ratchets, torque wrenches, and extension bars in professional and trade shop applications.

Installation Notes

Installation is performed by mechanics and trade technicians using standard 3/8 inch drive hand tools. Ensure the socket is fully seated on the fastener before applying torque to avoid rounding. Inspect the socket and drive square for wear or damage before use on safety-critical fasteners. Follow applicable shop safety practices and equipment manufacturer torque specifications when using with a torque wrench.
