Proto J5009M Deep Hand Socket 3/8 in Drive 9 Mm 12-pt

Product Description

The PROTO J5009M is a 12-point deep hand socket designed for professional hand-tool use in mechanical, HVAC, plumbing, and electrical service work. Built from chrome-plated steel, it accepts a 3/8 inch drive and fits a 9 mm fastener head. The deep length profile — 2-1/8 inches overall — provides the clearance needed to reach recessed or stud-mounted fasteners that a standard-depth socket cannot access. This socket meets ASME B107.110-2012, AS4984A, and SAE AS955 standards, making it appropriate for professional trade environments where tool certification matters.

The J5009M suits technicians working on mechanical systems where metric fasteners are common — HVAC equipment, refrigeration units, pumps, electrical panels, and plumbing assemblies. The deep length is especially useful when threading onto long bolts, studs, or fasteners seated inside recessed housings. The 12-point design allows engagement at multiple angles, useful in tight quarters where swing arc is limited. It is intended for hand-drive use with a 3/8 inch ratchet, breaker bar, or extension.

Key Features

• Deep length at 2-1/8 inches overall for access to recessed and stud-mounted fasteners
• 12-point socket geometry allows multiple engagement positions in confined spaces
• 3/8 inch drive compatible with standard ratchets, breaker bars, and extensions
• Chrome-plated steel construction for corrosion resistance and durability
• Meets ASME B107.110-2012, AS4984A, and SAE AS955 standards
• Not tether capable — intended for standard hand-tool use

Compatibility

Designed for use with any 3/8 inch drive ratchet, breaker bar, or extension bar accepting standard square-drive tooling. Fits 9 mm hex fasteners in metric applications across HVAC, plumbing, electrical, and general mechanical service.

Installation Notes

Intended for hand-tool use only — do not use with impact drivers, as this socket is not rated for impact service. Inspect the socket for cracks or rounding before use and replace if worn. Ensure the drive connection is fully seated before applying torque to avoid slippage or fastener damage.
