Proto J77415MP Impact Socket 3/8 in Drive 15mm 6-point

Product Description

The PROTO J77415MP is a 15mm, 6-point impact socket designed for use with a 3/8 inch drive impact wrench or ratchet. Built from alloy steel, it delivers the toughness required for high-torque fastening and removal tasks encountered in professional automotive, heavy equipment, and industrial service work. The hex drive style provides a secure, positive engagement with the fastener, reducing the risk of rounding. At 2-3/32 inches overall length, this socket fits standard-depth applications where clearance is not a limiting factor. It meets ASME B107.2 specifications, confirming it is manufactured and tested to recognized industry standards for impact sockets.

This socket is suited for professional technicians working in automotive repair shops, fleet maintenance facilities, and industrial maintenance environments. It handles fastener removal and installation on engines, suspension components, drivetrain assemblies, and general mechanical assemblies where a 15mm hex fastener is specified. The 3/8 inch drive size makes it compatible with compact impact wrenches and torque tools commonly used for mid-range fastener applications.

Key Features

• 3/8 inch drive fits standard impact wrenches and ratchets in this drive class

Compatibility

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

Installation Notes

Installation should be performed by qualified technicians familiar with impact tooling and torque requirements for the fastener application. Always verify the socket is fully seated on the drive anvil and fastener before applying torque. Use impact-rated sockets exclusively with impact wrenches — do not substitute chrome hand-tool sockets in impact applications. Follow applicable torque specifications for the equipment being serviced as defined by the equipment manufacturer.
