Proto j7008m Deep Socket 3/8 in Drive 6 Point 8mm

Product Description

The PROTO j7008m is a 6-point deep socket with a 3/8 inch drive, sized for 8mm fasteners and finished in black oxide. It features the TorquePlus internal drive geometry, which shifts contact away from fastener corners and distributes load across the flat faces instead. This radius-corner design reduces slippage, minimizes fastener rounding, and makes it easier to turn worn, rounded, or rusted fasteners. At 2-3/4 inches overall length, the deep profile provides clearance for extended fasteners and recessed bolt heads. The socket size is stamped directly on the tool for fast identification on the job.

This socket is suited for automotive, industrial, and mechanical service work where 8mm fasteners are common. The deep socket profile is useful when a standard-depth socket cannot reach the fastener fully, such as on wheel studs, suspension components, engine hardware, and similar recessed applications. The black oxide finish provides a degree of corrosion resistance for shop and field use. The side locking hole supports a pin or retaining ring for use with impact-rated accessories and extension setups.

Key Features

• TorquePlus drive design contacts fastener flats, not corners, reducing rounding and slippage
• Radius-corner geometry distributes contact stress over a larger surface area
• Effective on worn, rounded, or rusted fasteners
• Deep profile at 2-3/4 inches overall length for recessed fastener access
• Socket size stamped on tool for quick identification
• Side locking hole for pin or retaining ring retention
• Black oxide finish for corrosion resistance

Compatibility

Designed as an OEM-style deep socket for use with standard 3/8 inch drive ratchets, extensions, and impact tools requiring a 6-point 8mm socket.

Installation Notes

This socket is intended for use by automotive technicians, maintenance mechanics, and industrial service professionals. Ensure the drive tool and socket are fully seated before applying torque to avoid disengagement. Inspect the socket for cracks or wear before each use, particularly when used with impact drivers. Follow applicable shop safety practices and manufacturer torque specifications for the fastener being serviced.
