Proto J15052 Impact Socket 1-1/2 in Drive 3-1/4 in 6-point

Product Description

The PROTO J15052 is a heavy-duty impact socket designed for high-torque fastening applications in industrial, mechanical, and construction environments. Built around a 1-1/2 inch drive, it accepts 3-1/4 inch hex fasteners and features a 6-point contact geometry that maximizes torque transfer while reducing the risk of rounding fastener corners. The overall length of 4-23/32 inches suits deep-reach applications where clearance is limited. Licensed mechanics, millwrights, and heavy equipment technicians rely on impact-rated sockets like this one when running high-output pneumatic or hydraulic impact wrenches.

This socket is suited for heavy industrial, commercial, and fleet maintenance applications where large hex fasteners are standard. Typical use cases include structural bolting, large machinery assembly, and heavy-duty vehicle or equipment service. The 1-1/2 inch drive size places this socket in the category of tooling used with full-size industrial impact wrenches, making it appropriate for shops and field crews working on equipment with large-diameter fasteners that require significant torque output.

Key Features

• 1-1/2 inch drive size for use with full-size industrial impact wrenches
• 3-1/4 inch socket size fits large hex fasteners common in heavy equipment and structural applications
• 6-point drive geometry maximizes torque transfer and reduces fastener rounding
• 4-23/32 inch overall length provides reach in tight or recessed fastener locations
• Impact-rated construction designed to withstand repeated high-torque use

Compatibility

Designed as an OEM-style replacement or direct-fit impact socket for use with 1-1/2 inch drive industrial impact wrenches and drive tools.

Installation Notes

Installation and removal should be performed by qualified mechanics or technicians familiar with large-drive impact tooling. Always verify the socket is fully seated on the drive anvil and fastener before applying torque. Do not use impact sockets with standard hand-drive ratchets, as impact sockets are engineered for dynamic loading from pneumatic or hydraulic tools. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
