Proto J5224M Hand Socket 24mm 12-point 3/8 Drive

Product Description

The PROTO J5224M is a 24 mm, 12-point hand socket designed for 3/8 inch drive ratchets, breaker bars, and extensions. Built from alloy steel with a chrome-plated finish, it delivers the corrosion resistance and surface hardness required for professional use. The socket measures 1-5/16 inches in overall length, placing it in the standard-length category. It meets AS4984A and ASME B107.110-2012 standards, making it a compliant choice for both shop and field applications. Mechanics, maintenance technicians, and industrial trades reach for this socket when working on metric fasteners across a wide range of equipment.

The J5224M suits residential and commercial maintenance, automotive service, equipment repair, and general industrial applications wherever a 24 mm metric fastener is present. The 12-point design engages fasteners at 30-degree increments, providing more ratchet swing positions in confined spaces. Standard length fits the majority of open-access fastener locations. At 0.23 pounds, it is lightweight enough for sustained use without hand fatigue. This socket is a straightforward replacement or addition for any 3/8 inch drive metric socket set.

Installation Notes

This socket is installed and used by mechanics, maintenance technicians, and general tradespeople. Verify the fastener size before applying torque to avoid rounding. Ensure the socket is fully seated on the fastener and the drive tool before applying force. This socket is not tether capable and should not be used in overhead or elevated work environments where dropped-tool hazards exist.
