Proto J10020 Impact Socket 1 in Drive 1-1/4 in 6-point

Product Description

The PROTO J10020 is a 1 inch drive, 6-point impact socket designed for heavy-duty fastener removal and installation in demanding trade and industrial applications. Built around a 1-1/4 inch hex socket size, this socket delivers the torque transfer and wall strength required for high-output impact wrenches. The 6-point geometry concentrates force on the flat faces of the fastener, reducing the risk of rounding under high torque. At 2-5/8 inches overall length, it fits standard 1 inch drive impact tool anvils used by mechanics, ironworkers, and industrial maintenance technicians.

This socket is suited for structural steel assembly, heavy equipment maintenance, agricultural machinery, and industrial plant work where 1 inch drive impact tools are the standard. The 1-1/4 inch size addresses common fastener sizes found on large frame equipment, truck chassis components, and structural bolted connections. Technicians working in manufacturing, fleet maintenance, and field construction will find this socket addresses the fastener range typical to those environments.

Key Features

• 1 inch square drive fits standard heavy-duty impact wrenches and drive extensions
• 1-1/4 inch hex socket size for common large-frame fastener applications
• 6-point contact geometry reduces fastener rounding under high-torque impact use
• 2-5/8 inch overall length provides a compact profile for use in tighter access points
• Impact-rated construction designed to absorb the rotational shock loads of pneumatic and electric impact tools

Compatibility

Designed as an OEM-style replacement and standard fitment impact socket for 1 inch square drive impact wrenches used in heavy industrial, structural, and fleet maintenance applications.

Installation Notes

Installation and use should be performed by qualified mechanics or maintenance technicians familiar with 1 inch drive impact tooling. Always confirm the socket is fully seated on the impact wrench anvil and the retaining pin or ring is secure before applying torque. Do not use impact sockets with standard ratchets or torque wrenches, as impact-rated and hand-tool-rated sockets are not interchangeable under shock load conditions. Inspect the socket for cracks or deformation before each use and remove from service if damage is present.
