Proto J7218S Impact Socket 3/8 in Drive 9/16 in 8-point

Product Description

The PROTO J7218S is an 8-point impact socket designed for use with 3/8 inch drive impact wrenches and ratchets. It accepts a 9/16 inch fastener size and measures 1 inch in overall length, making it a compact option for tight-clearance applications. Built for the demands of impact tooling, this socket is suited for professional mechanics, industrial maintenance technicians, and trade contractors who require reliable drive-tool accessories for fastener removal and installation under high-torque conditions.

This socket is appropriate for automotive, mechanical, and general industrial service applications where a 3/8 inch drive impact tool is in use. The 9/16 inch size covers a common fastener dimension found across light-duty vehicles, equipment frames, and structural assemblies. Its short overall length of 1 inch suits confined spaces where a standard or deep socket would not fit cleanly.

Key Features

• 3/8 inch drive connection compatible with standard impact wrenches and ratchets
• 9/16 inch socket size for common fastener applications
• 8-point socket design for secure fastener engagement
• 1 inch overall length for use in tight or confined spaces
• Lightweight at 0.17 pounds for reduced tool fatigue

Compatibility

Designed as an OEM-style replacement and standard-fit impact socket for 3/8 inch drive impact wrenches, ratchets, and extension bars accepting 9/16 inch fasteners.

Installation Notes

This socket is installed and used by mechanics, millwrights, and maintenance technicians working with 3/8 inch drive impact tools. Ensure the socket is fully seated on the drive anvil before applying torque. Inspect the socket for cracks or wear before each use, and never use impact sockets on hand-ratchet tools where the drive retainer is not rated for impact loads.
