Proto J15074 Impact Socket 1-1/2 in Drive 4-5/8 in 6-point

Product Description

The PROTO J15074 is a heavy-duty impact socket designed for high-torque fastening applications in industrial, construction, and mechanical service environments. Built on a 1-1/2 inch drive, it accepts a 4-5/8 inch hex fastener and features a 6-point contact geometry that maximizes torque transfer while reducing the risk of rounding fastener corners. The overall length is 6-1/4 inches. This socket is intended for use with 1-1/2 inch drive impact wrenches and is typically installed by millwrights, industrial mechanics, and heavy equipment technicians working on large-diameter fasteners.

This impact socket suits heavy industrial and infrastructure applications where large hex fasteners are common, including structural steel assembly, pipeline flanges, heavy equipment maintenance, and large-format HVAC or mechanical equipment installation. The 1-1/2 inch drive platform is standard in industrial power tool setups. At 29.98 pounds, this is a substantial tool appropriate for stationary or floor-mounted impact wrench use rather than overhead or confined-space work.

Key Features

• 1-1/2 inch drive size compatible with industrial-class impact wrenches
• 4-5/8 inch socket size for large hex fasteners
• 6-point drive geometry reduces fastener rounding under high torque
• Hex drive style for direct engagement on hex-head fasteners and bolts
• 6-1/4 inch overall length provides reach in recessed or flanged applications

Compatibility

Designed as an OEM-style replacement and standard fitment for 1-1/2 inch drive industrial impact wrenches requiring a 4-5/8 inch 6-point hex socket.

Installation Notes

Installation and use should be performed by qualified mechanics or millwrights familiar with large-drive impact tooling. Always ensure the impact wrench is powered down and depressurized before changing sockets. Confirm the socket is fully seated on the drive anvil and the retaining pin or ring is engaged before applying torque. Do not use impact sockets with hand-drive ratchets, as impact-rated tools are designed for percussion loading only.
