Proto J10018T Impact Socket 1 in Drive 1-1/8 in 12-pt

Product Description

The PROTO J10018T is a 12-point impact socket built for heavy-duty fastener work in industrial and mechanical service environments. Designed for use with a 1 inch drive impact wrench, it accepts 1-1/8 inch fasteners and measures 2-9/16 inches overall length. The chrome steel construction provides the strength and hardness needed to handle the rotational shock loads produced by pneumatic and hydraulic impact tools. This socket is suited for licensed mechanics, millwrights, fleet technicians, and industrial maintenance professionals who need reliable torque transfer on large fasteners without socket failure under load.

The J10018T fits common heavy-duty applications including truck drivetrain service, heavy equipment maintenance, industrial machinery assembly, and structural fastener work. The 12-point design allows easier engagement in tight or partially obstructed spaces compared to a 6-point socket, making it practical in confined work areas where socket alignment is difficult. It is appropriate for both shop and field use wherever a 1 inch drive impact tool is standard.

Key Features

• 1 inch drive size for use with heavy-duty impact wrenches and drive tools
• 1-1/8 inch socket opening accepts standard and heavy-hex fasteners
• 12-point design for easier socket-to-fastener engagement in restricted access areas
• Chrome steel construction engineered to withstand impact tool shock loads
• 2-9/16 inch overall length suits standard reach applications
• Compact package profile fits tool rolls, trays, and organized socket sets

Compatibility

Designed as an OEM-style replacement or addition for 1 inch drive impact socket sets used in heavy-duty mechanical and industrial service applications.

Installation Notes

Installation of this socket requires a compatible 1 inch drive impact wrench or breaker bar. Always verify the socket is fully seated on both the drive anvil and the fastener head before applying torque. Inspect the socket for cracks or deformation before each use and remove it from service if damage is found. Do not use impact sockets with standard hand-drive ratchets unless the tool is rated for impact use.
