Proto J15063 Impact Socket 1-1/2 in Drive 3-15/16 in 6-pt

Product Description

The PROTO J15063 is a heavy-duty impact socket designed for use with 1-1/2 inch square drive impact wrenches. It features a 3-15/16 inch hex opening with a 6-point drive geometry, which maximizes contact on fastener flats and reduces the risk of rounding. The overall length is 5-1/2 inches. At 21.33 pounds, this is a substantial, professional-grade socket built for high-torque applications in industrial, heavy equipment, and fleet maintenance environments. Licensed mechanics, industrial technicians, and heavy equipment service crews are the primary installers.

This socket fits applications where large hex fasteners must be driven or removed under high torque conditions. Typical use cases include heavy truck axle work, construction equipment maintenance, large-scale structural fastening, and industrial machinery service. The 6-point configuration is preferred for impact use because it distributes force evenly across the fastener, reducing fastener damage during high-torque drive cycles. This socket is sold individually.

Key Features

• Built for high-torque industrial and heavy equipment service environments

Compatibility

Designed as an OEM-style impact socket for use with 1-1/2 inch drive impact wrenches in heavy-duty industrial and fleet maintenance applications.

Installation Notes

Installation is performed by licensed mechanics or industrial technicians using a 1-1/2 inch drive impact wrench or breaker bar. Always confirm the socket drive size matches the tool drive before applying torque. Inspect the socket for cracks or deformation before each use, and never use impact sockets with standard hand-drive ratchets beyond their rated capacity. Follow applicable workplace safety codes when working on heavy equipment or pressurized systems.
