Proto J15072 Impact Socket 1-1/2 in Drive 4-1/2 in 6-pt

Product Description

The PROTO J15072 is a heavy-duty impact socket designed for high-torque fastening and removal applications in industrial, construction, and mechanical service environments. Built on a 1-1/2 inch drive, this socket accepts a 4-1/2 inch hex fastener and features a 6-point contact geometry that delivers full-surface engagement on hex fasteners, reducing corner rounding under load. The overall length is 6 inches. At 28.4 pounds, this is a substantial tool suited for large-scale equipment service. Licensed tradespeople and heavy equipment mechanics are the primary users.

This impact socket is appropriate for heavy industrial maintenance, large-format mechanical assembly, and infrastructure or utility service work where 1-1/2 inch drive impact tools are standard. Typical applications include large pump and compressor service, structural bolting, heavy equipment repair, and industrial machinery maintenance. The 6-point hex drive profile makes it well suited for work on large hex fasteners where torque demands are high and fastener integrity must be preserved.

Key Features

• 1-1/2 inch drive size for use with heavy-duty impact wrenches and drive tools
• 4-1/2 inch socket size with 6-point hex drive geometry for full-face fastener contact
• 6 inch overall length provides clearance in recessed or obstructed fastener locations
• Designed for impact tool use, not hand-drive ratchets
• Single-piece package quantity suitable for individual tool procurement or fleet stocking

Compatibility

Designed for use with 1-1/2 inch drive impact wrenches and drive tools that accept standard square-drive impact sockets in industrial and heavy equipment service applications.

Installation Notes

This socket is intended for use by qualified mechanics and tradespeople operating 1-1/2 inch drive pneumatic or hydraulic impact tools. Always de-energize or depressurize connected systems before breaking or torquing fasteners on pressurized equipment. Use only impact-rated sockets with impact wrenches — do not substitute chrome hand-drive sockets. Verify fastener size and socket seating before applying torque to avoid socket ejection or fastener damage.
