Proto J10027 Impact Socket 1 in Drive 1-11/16 in 6-point

Product Description

The PROTO J10027 is a 1-inch drive, 6-point impact socket designed for heavy-duty fastener removal and installation in demanding trade environments. Built around a hex drive interface, it accepts 1-11/16 inch fasteners and carries an overall length of 2-13/16 inches. The 6-point contact geometry distributes torque evenly across fastener flats, reducing the risk of rounding under high-impact load. At 2.18 pounds, it is sized for use with industrial-grade impact wrenches. This socket is the type of tool used by millwrights, heavy equipment mechanics, pipefitters, and industrial maintenance technicians working on large bolted assemblies where a standard 1/2-inch drive socket is insufficient.

The J10027 is suited for commercial and industrial applications where large-diameter fasteners are standard. Typical install scenarios include structural steel connections, heavy machinery maintenance, large-diameter flange bolting, and industrial equipment assembly. Its 1-inch drive size positions it for use with full-size pneumatic or hydraulic impact wrenches rather than cordless hand tools. Technicians working in HVAC mechanical rooms, pump stations, compressor skids, and large chiller installations will encounter fastener sizes in this range regularly.

Key Features

• 1-inch drive size for use with full-size pneumatic or hydraulic impact wrenches
• 1-11/16 inch socket size for large-diameter hex fasteners
• 6-point design concentrates torque on fastener flats, not corners
• 2-13/16 inch overall length provides clearance in tight bolt access situations
• Rated for impact use, not hand-tool service only

Compatibility

Designed as an OEM-style impact socket for use with 1-inch drive pneumatic, hydraulic, or electric impact wrenches accepting standard square-drive tooling.

Installation Notes

Impact sockets should only be used with impact wrenches — do not use with standard ratchets or torque wrenches, as wall thickness and steel temper differ from chrome hand-tool sockets. Verify the drive pin and retaining ring or hog ring are fully seated before applying torque. Always wear appropriate eye and hand protection when operating impact wrenches at high torque settings. Follow applicable OSHA and facility safety guidelines for powered hand tool use.
