Proto J7315M Impact Socket 1/2 in Drive 15mm 6-point

Product Description

The PROTO J7315M is a 15mm, 6-point impact socket designed for use with 1/2 inch drive impact wrenches and ratchets. Built for high-torque fastening applications, this socket features a hex drive configuration and measures 3.25 inches overall length, giving clearance in recessed or tight fastener locations. The 6-point geometry provides maximum contact surface on fastener flats, reducing the risk of rounding under impact loads. At 0.4 pounds, it is a solid, tool-belt-ready piece suited to professional trades work in mechanical, industrial, and field service environments. Installation and removal of hex fasteners in demanding conditions is the core application for this socket.

This socket is suited for use in automotive, industrial maintenance, HVAC equipment service, plumbing rough-in, and general mechanical assembly where 15mm hex fasteners are encountered. The 1/2 inch drive size is the standard for mid-range to heavy-duty impact tools found on most service trucks and shop benches. Technicians working on compressors, pumps, structural brackets, flanges, and equipment frames will find the 3.25 inch overall length useful for reaching fasteners in moderately recessed positions without an extension.

Key Features

• 15mm socket size with 6-point contact geometry for secure grip on hex fasteners under impact
• 1/2 inch drive compatible with standard mid-range and heavy-duty impact wrenches and ratchets
• 3.25 inch overall length provides reach into moderately recessed fastener locations
• Hex drive style ensures positive engagement and reduces cam-out during high-torque operation
• Compact 0.4 pound weight keeps tool load manageable during extended use

Compatibility

Designed for use with 1/2 inch drive impact wrenches, air ratchets, and hand ratchets. Fits standard 15mm hex fasteners encountered across mechanical, HVAC, plumbing, and industrial service applications.

Installation Notes

Impact sockets should only be used with impact-rated drive tools — do not substitute chrome hand-socket tools in impact applications. Before use, inspect the socket for cracks, deformation, or wear on the drive square and socket walls. Ensure the socket is fully seated on the fastener and the drive tool retaining pin or ring is engaged before applying torque. Follow applicable workplace safety standards when working with powered impact tools.
