Proto J10019L Impact Socket 1 in Drive 1-3/16 in 6-point

Product Description

The PROTO J10019L is a heavy-duty impact socket designed for use with 1-inch drive impact wrenches. Built for 6-point hex drive engagement, it accepts a 1-3/16 inch fastener and delivers the torque transfer needed for demanding industrial, mechanical, and construction applications. With an overall length of 3.75 inches, the socket provides adequate clearance for recessed or deep-set fasteners without sacrificing stability. Licensed tradespeople and experienced mechanics rely on impact-rated sockets like this one to handle the high-torque output of pneumatic and electric impact tools safely and consistently.

This socket is suited for heavy equipment maintenance, fleet service, structural assembly, and similar applications where a 1-inch drive tool is standard. The 6-point design concentrates force on the flat faces of the fastener rather than the corners, reducing the risk of rounding off hardware under high-torque conditions. It is a practical choice for shop technicians, field mechanics, and industrial maintenance crews working with large-diameter fasteners in commercial or industrial settings.

Key Features

• 1-inch square drive fits standard heavy-duty impact wrenches and breaker bars
• 1-3/16 inch socket size for large fastener applications
• 6-point hex drive geometry reduces fastener rounding under high torque
• 3.75 inch overall length provides reach for recessed fastener locations
• Impact-rated construction for use with pneumatic and electric impact tools

Compatibility

Designed as an OEM-style impact socket for use with 1-inch drive impact wrenches, torque multipliers, and breaker bars requiring a 1-3/16 inch hex socket.

Installation Notes

Installation and removal should be performed by a qualified mechanic or maintenance technician familiar with impact tooling. Always verify the socket is fully seated on the drive anvil and fastener before applying torque. 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 unless the socket is also rated for hand-tool use.
