Proto J15047 Impact Socket 1-1/2 in Drive 2-15/16 in 6-pt

Product Description

The PROTO J15047 is a heavy-duty impact socket designed for high-torque fastener work in industrial, mechanical, and trade environments. Built on a 1-1/2 inch drive, it accepts a 2-15/16 inch hex fastener and features a 6-point contact geometry for maximum engagement and reduced fastener rounding under impact load. With an overall length of 4.5 inches, this socket is sized for demanding applications where standard hand-tool sockets would fail under the stress of pneumatic or hydraulic impact wrenches. It is installed and used by millwrights, heavy equipment mechanics, pipefitters, and industrial maintenance technicians working with large-diameter fasteners.

This impact socket is suited for use with 1-1/2 inch drive impact wrenches on heavy industrial assemblies, structural connections, large machinery, and equipment requiring high break-away torque. Applications include compressor assembly, pump installation, structural steelwork, and large HVAC or mechanical equipment mounting where oversized fasteners are standard. The 6-point design is preferred in professional settings because it applies force to the flat faces of the fastener rather than the corners, preserving fastener integrity under repeated impact use.

Key Features

• 1-1/2 inch drive size for use with heavy-duty impact wrenches
• 2-15/16 inch socket size fits large hex fasteners common in industrial applications
• 6-point contact geometry reduces fastener rounding and increases torque transfer
• 4.5 inch overall length provides clearance and reach in tight or recessed bolt positions
• Hex drive style for direct engagement with hex-head fasteners and bolts

Compatibility

Designed for use with 1-1/2 inch drive impact wrenches and drive tools. Fits 2-15/16 inch hex fasteners in industrial and heavy mechanical applications.

Installation Notes

This socket is intended for use by qualified mechanics and tradespeople with 1-1/2 inch drive impact equipment. Always verify the socket is fully seated on both the drive tool and the fastener before applying torque. Inspect the socket for cracks, chips, or wear before each use and remove from service if damage is found. Never use impact sockets with hand-drive ratchets, as impact-rated and hand-tool materials have different mechanical properties.
