Proto J15053 Impact Socket 1-1/2 in Drive 3-5/16 in 6-point

Product Description

The PROTO J15053 is a heavy-duty impact socket designed for high-torque fastening applications in professional trade environments. Built around a 1-1/2 inch drive, it accepts 3-5/16 inch hex fasteners and features a 6-point contact geometry that maximizes surface contact on fastener flats to reduce rounding under load. The overall length of 4-23/32 inches provides the reach needed for recessed or partially obstructed fastener locations. This socket is intended for use with 1-1/2 inch drive impact wrenches and is suited to heavy mechanical, industrial, and structural assembly work performed by journeymen mechanics and millwrights.

This impact socket fits applications where large-format hex fasteners are standard, including heavy equipment repair, structural steel assembly, pipeline flange work, and industrial machinery maintenance. The 1-1/2 inch drive size places this tool in the heavy industrial category, most commonly found in shop environments, field service rigs, and fleet maintenance facilities. It is compatible with pneumatic, hydraulic, and electric impact wrenches using a 1-1/2 inch square drive.

Compatibility

Designed as an OEM-style replacement and standard-service impact socket for 1-1/2 inch drive impact wrenches used in heavy industrial and mechanical trade applications.

Installation Notes

Installation and removal should be performed by qualified mechanics or millwrights familiar with large-drive impact tooling. Ensure the impact wrench is rated for the drive size and torque range of the application before use. Never use impact sockets with standard ratchet handles, as impact-rated sockets are engineered for the shock loads of impact tools and standard handles are not. Inspect the socket for cracks or wear before each use and replace if damage is found.
