Proto J15054 Impact Socket 1-1/2 in Drive 3-3/8 in 6-pt

Product Description

The PROTO J15054 is a heavy-duty impact socket designed for high-torque fastening and removal applications. Built around a 1-1/2 inch drive, it accepts a 3-3/8 inch hex fastener with a 6-point contact pattern that concentrates force on the flats of the fastener rather than the corners. This reduces rounding and fastener damage under impact load. The overall length of 4-23/32 inches provides adequate reach in tight service environments. It is the type of socket used by industrial mechanics, fleet technicians, and heavy-equipment service professionals who work with large-format fasteners on a routine basis.

This socket is suited for heavy industrial, construction equipment, and fleet maintenance applications where 1-1/2 inch drive impact tools are standard. The 6-point hex drive geometry makes it appropriate for large structural bolts, axle nuts, and heavy machinery fasteners found in commercial and industrial settings. Technicians working on large trucks, agricultural equipment, or structural steel assemblies will find the drive size and socket capacity within the expected range for those applications.

Key Features

• 1-1/2 inch drive fits standard heavy-duty impact wrenches and drive tools
• 3-3/8 inch socket size handles large hex fasteners common in industrial and fleet work
• 6-point contact pattern reduces fastener rounding under high-torque impact loads
• 4-23/32 inch overall length provides reach in recessed or confined fastener locations
• Hex drive style for direct engagement on hex-head bolts and nuts

Compatibility

Designed as an OEM-style impact socket compatible with standard 1-1/2 inch square drive impact wrenches and manual drive tools used in heavy industrial and fleet maintenance applications.

Installation Notes

This socket is installed and serviced by industrial mechanics, fleet technicians, and heavy-equipment service professionals. Always ensure the drive tool is powered down or depressurized before attaching or removing impact sockets. Verify that the socket is fully seated on the drive anvil and that the retaining pin or ring is engaged before applying torque. Do not use impact sockets with standard hand-drive ratchets not rated for impact loads.
