Proto J15071 Impact Socket 1-1/2 in Drive 4-7/16 in 6-pt

Product Description

The PROTO J15071 is a heavy-duty impact socket designed for use with 1-1/2 inch drive impact wrenches and ratchets. It accepts a 4-7/16 inch hex fastener using a 6-point contact pattern, which distributes torque evenly across the fastener flats to reduce rounding. The overall length of 6 inches provides clearance for recessed or deep-set fasteners. At 29.8 pounds, this is a substantial industrial-grade socket built for demanding torque applications. It is sized for large-format fastener work common in heavy equipment maintenance, structural steel assembly, and industrial machinery service.

This socket is suited for industrial, construction, and heavy equipment service environments where large hex fasteners require high-torque impact driving. The 1-1/2 inch drive size places it in the heavy industrial category, typically used with large pneumatic or hydraulic impact wrenches. Applications include bolt-up work on structural steel, heavy machinery, mining equipment, and large commercial HVAC or mechanical systems requiring oversized fastener removal and installation.

Key Features

• 1-1/2 inch drive size for use with heavy industrial impact wrenches and ratchets
• 4-7/16 inch hex socket opening for large-format fasteners
• 6-point contact pattern reduces fastener rounding under high torque
• 6 inch overall length provides reach into recessed fastener locations
• Built for impact use — designed to absorb the shock loads generated by impact tools

Compatibility

Designed as an OEM-style replacement and standard-fit socket for 1-1/2 inch drive impact tools requiring a 4-7/16 inch 6-point hex socket.

Installation Notes

Installation and removal should be performed by qualified mechanics or tradespeople familiar with large-drive impact tooling. Ensure the impact wrench or ratchet drive is rated for 1-1/2 inch drive before use. Inspect the socket for cracks or wear before each use — do not use impact sockets that show signs of deformation. Never use impact sockets with hand-drive torque tools, as the steel alloy and wall thickness are optimized for impact loads, not controlled torque application.
