Proto J07528L Impact Socket 3/4 in Drive 1-3/4 in 6-point

Product Description

The PROTO J07528L is a 3/4 inch drive impact socket designed for high-torque fastening and removal applications. It features a 1-3/4 inch hex socket opening with a 6-point contact pattern, which distributes force evenly across fastener flats to reduce rounding under impact loads. The overall length is 3-7/8 inches. At 2.68 pounds, it is built to handle the demands of heavy-duty pneumatic and hydraulic impact wrenches. This socket is used by mechanics, millwrights, and industrial maintenance technicians who work with large fasteners on equipment, machinery, and structural assemblies.

This socket fits into applications where a 3/4 inch drive impact wrench is the tool of choice — typically commercial vehicle service, heavy equipment maintenance, structural steel work, and industrial facility maintenance. The 6-point design is preferred over 12-point in impact use because it grips fastener flats rather than corners, which is critical when breaking loose seized or high-torque fasteners. The 1-3/4 inch size is common on agricultural equipment, large trucks, and industrial machinery fasteners.

Key Features

• 3/4 inch drive fits standard heavy-duty impact wrenches and drive tools
• 1-3/4 inch hex socket opening for large fastener applications
• 6-point contact pattern reduces fastener rounding under impact
• 3-7/8 inch overall length suits standard-depth fastener access
• Built for impact use with pneumatic or hydraulic wrenches

Compatibility

Designed for use with 3/4 inch drive impact wrenches and ratchets in heavy-duty industrial, commercial vehicle, and equipment service applications.

Installation Notes

This socket is installed and removed by qualified mechanics and industrial maintenance technicians. Always verify the drive size of the impact wrench matches the 3/4 inch drive of this socket before use. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Do not use impact sockets with hand-drive ratchets as a substitute for proper impact tooling.
