Proto J78419MP Impact Socket 3/8 in Drive 19mm 6-pt

Product Description

The PROTO J78419MP is a 3/8 inch drive impact socket designed for high-torque fastening applications in professional trade environments. Built from alloy steel, this 6-point hex drive socket measures 19mm and has an overall length of 2-13/16 inches. The 6-point design concentrates force on the flat faces of the fastener, reducing the risk of rounding under heavy impact loads. It meets ASME B107.2 standards, confirming dimensional and performance compliance expected in industrial and mechanical service work. Mechanics, millwrights, and general maintenance technicians rely on this socket for reliable torque transfer in demanding conditions.

This socket is suited for automotive service, heavy equipment maintenance, and industrial assembly applications where a 3/8 inch drive impact tool is standard. The 19mm size covers common metric fasteners found on engines, suspension components, and structural assemblies. Its universal style makes it a practical addition to any impact socket set used in shop or field environments. The compact overall length of 2-13/16 inches allows access in moderate-clearance situations without requiring an extension in many standard applications.

Compatibility

Designed as an OEM-style impact socket compatible with standard 3/8 inch drive impact wrenches, air ratchets, and hand ratchets used in automotive, industrial, and mechanical service applications.

Installation Notes

Installation and use should be performed by qualified mechanics or maintenance technicians familiar with impact tooling. Always verify the drive size of the impact tool matches the 3/8 inch square drive before use. Do not use impact sockets with non-impact hand tools in high-torque applications beyond the tool rating. Inspect the socket for cracks or wear before each use, and replace if deformation is observed.
