Proto J15064 Impact Socket 1-1/2 in Drive 4 in Hex

Product Description

The PROTO J15064 is a heavy-duty 6-point impact socket designed for high-torque fastening and removal applications. Built around a 1-1/2 inch drive, it accepts a 4 inch hex fastener and measures 5-1/2 inches overall length. The 6-point design concentrates force on the flats of the fastener rather than the corners, reducing the chance of rounding during impact use. At 20.66 pounds, this is a substantial tool intended for industrial and heavy equipment service. Technicians working with large hex fasteners on structural assemblies, heavy machinery, or industrial equipment will find this socket suited to high-demand impact wrench applications.

This socket fits into service scenarios involving large-format hex drive fasteners found in industrial equipment, heavy trucks, agricultural machinery, and structural mechanical assemblies. The 1-1/2 inch drive size is standard in heavy industrial impact tooling and pairs with full-size industrial impact wrenches. It is well suited for maintenance, repair, and overhaul work where high breakaway torque is required. Professional mechanics and industrial maintenance technicians are the primary users of this socket size.

Key Features

• 1-1/2 inch drive size for use with heavy industrial impact wrenches
• 4 inch hex socket size for large-format fasteners
• 6-point design reduces corner rounding under high-torque impact loads
• 5-1/2 inch overall length provides clearance in deep or recessed fastener applications
• Heavy construction at 20.66 pounds suitable for sustained industrial use

Compatibility

Designed as an OEM-style replacement or service-grade socket for 1-1/2 inch drive industrial impact wrenches requiring a 4 inch hex socket.

Installation Notes

Installation and use should be performed by qualified mechanical technicians familiar with high-torque impact tooling. Always confirm the drive size of the impact wrench matches the 1-1/2 inch drive of this socket before use. Inspect the socket for cracks or wear before each use, and never use impact sockets with hand-drive ratchets. Secure the socket fully onto the drive anvil and verify fastener seating before applying torque.
