Proto J10048L Impact Socket 1 in Drive 3 in 6-point

Product Description

The PROTO J10048L is a heavy-duty impact socket designed for high-torque fastening and removal applications in professional trades. Built from alloy steel, this socket features a 1-inch square drive and a 3-inch hex socket size with a 6-point contact pattern. The 6-point design concentrates force on the flat faces of the fastener, reducing rounding under heavy impact loads. At 5 inches overall length, it provides the reach needed for deep or recessed fastener access. Installed by mechanics, industrial maintenance technicians, and trade professionals who run 1-inch drive impact wrenches in demanding service environments.

This socket is suited for heavy equipment maintenance, fleet service, structural steel work, and industrial assembly applications where large-diameter fasteners require consistent, high-torque drive. The 1-inch drive size is standard for heavy-duty pneumatic and hydraulic impact tools used in commercial and industrial settings. Its alloy steel construction handles the cyclic stress and shock loading inherent to impact tool use without fracturing or deforming under normal service conditions.

Key Features

• 1-inch square drive compatible with heavy-duty impact wrenches and drive tools
• 3-inch hex socket size for large-diameter fastener applications
• 6-point contact geometry reduces fastener rounding under high torque
• Alloy steel construction rated for impact service stress and shock loading
• 5-inch overall length provides reach for recessed or deep fastener access

Compatibility

Designed as an OEM-style replacement and service socket for 1-inch drive impact tool systems used in heavy-duty industrial and fleet maintenance applications.

Installation Notes

Installation and use should be performed by qualified mechanics or trade professionals familiar with 1-inch drive impact equipment. Always verify the socket is fully seated on the drive anvil and fastener before applying torque. Do not use impact sockets with hand-drive ratchets, as impact-rated and hand-tool-rated sockets are not interchangeable. Inspect the socket for cracks or deformation before each use and remove from service if damage is observed.
