Proto J15076 Impact Socket 1-1/2 in Drive 4-3/4 in 6-point

Product Description

The PROTO J15076 is a heavy-duty impact socket designed for high-torque fastening applications in industrial, mechanical, and maintenance settings. Built around a 1-1/2 inch drive, it accepts a 4-3/4 inch hex fastener with a 6-point contact pattern that distributes force evenly across the fastener flats, reducing rounding and improving grip under load. The overall length is 6-1/4 inches, making it suited for applications where clearance and reach both matter. Licensed mechanics, millwrights, and heavy equipment technicians are the primary users of sockets in this drive class.

This socket is used in heavy industrial and construction environments where large hex fasteners are standard. Typical applications include structural steel assembly, large-bore flange work, heavy machinery maintenance, and utility equipment service. The 1-1/2 inch drive size places this tool firmly in the professional heavy-duty category, requiring a matching 1-1/2 inch drive impact wrench or breaker bar to operate.

Key Features

• 1-1/2 inch drive size for high-torque impact wrench compatibility
• 4-3/4 inch hex socket size for large industrial fasteners
• 6-point drive geometry reduces fastener rounding under load
• 6-1/4 inch overall length provides reach in deep or recessed applications
• Impact-rated construction for use with pneumatic and hydraulic impact tools

Compatibility

Designed for use with 1-1/2 inch drive impact wrenches, breaker bars, and torque multipliers that accept standard square-drive impact sockets.

Installation Notes

This socket should be used only with tools rated for 1-1/2 inch drive operation. Always confirm the impact wrench or torque tool is rated for the torque output being applied. Inspect the socket for cracks or deformation before each use and replace if any damage is found. Do not use impact sockets with standard hand-drive ratchets not rated for impact loads.
