Proto J7319M Impact Socket 1/2 in Drive 19mm 6-point

Product Description

The PROTO J7319M is a 6-point impact socket designed for heavy-duty fastener removal and installation in professional trade environments. Built for a 1/2 inch square drive, it accepts a 19mm hex fastener and measures 3.25 inches overall length. The 6-point geometry maximizes contact on the fastener flats, reducing the risk of rounding under high torque impact loads. This socket is intended for use with 1/2 inch drive impact wrenches and is sized for a common fastener dimension found across automotive, mechanical, and industrial applications. It weighs 0.52 pounds.

The J7319M suits professional mechanics, millwrights, and maintenance technicians working in automotive, fleet, construction equipment, and general mechanical service. The 19mm size is a standard fastener dimension appearing frequently on wheel lugs, suspension components, and structural hardware. It is appropriate for both shop and field use wherever a 1/2 inch drive impact tool is employed.

Key Features

• 1/2 inch square drive for compatibility with standard impact wrenches
• 19mm socket size fits common metric hex fasteners
• 6-point drive style maximizes flat contact and reduces fastener rounding
• 3.25 inches overall length provides reach in standard access applications
• Compact weight of 0.52 pounds for reduced fatigue during extended use

Compatibility

Designed as an OEM-style replacement or direct-fit impact socket for use with 1/2 inch drive impact wrenches accepting standard square-drive sockets.

Installation Notes

This socket is installed and removed by licensed mechanics and trade technicians using 1/2 inch drive impact wrenches or breaker bars. Ensure the socket is fully seated on the drive anvil before applying torque. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Do not use impact sockets on non-impact hand ratchets beyond their rated torque range.
