Proto J10020L Impact Socket 1 in Drive 1-1/4 in 6-pt

Product Description

The PROTO J10020L is a 1 inch drive, 1-1/4 inch, 6-point impact socket built for heavy-duty fastener work in professional trade and industrial environments. Designed to handle the high-torque output of pneumatic and hydraulic impact wrenches, this socket features a hex drive configuration and measures 3-3/4 inches overall length. The 6-point contact geometry reduces the risk of fastener rounding under load, making it well suited for high-stress applications where fastener condition matters. At 2.25 pounds, the J10020L is a solid, full-size impact-rated tool appropriate for licensed mechanics, pipefitters, millwrights, and heavy-equipment technicians.

This socket is used in applications requiring a large-drive impact tool, including industrial equipment assembly, structural steel work, heavy HVAC equipment installation, large-diameter pipe flange bolting, and commercial mechanical contracting. The 1 inch drive size is standard in heavy industrial and contractor-grade impact wrench setups. The 1-1/4 inch socket size is commonly encountered on large fasteners in HVAC equipment frames, mechanical rooms, and structural assemblies.

Key Features

• 1 inch drive size compatible with heavy-duty impact wrenches
• 1-1/4 inch socket size for large fastener applications
• 6-point contact geometry reduces fastener rounding under high torque
• Hex drive style for secure engagement with impact tool anvils
• 3-3/4 inch overall length provides reach in standard fastener access situations
• Rated for impact use, not intended for hand-ratchet-only applications

Compatibility

Designed as an OEM-specification impact socket for use with 1 inch drive pneumatic, hydraulic, or electric impact wrenches in heavy industrial and commercial trade settings.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with impact tool safety practices. Always verify the socket is fully seated on the impact wrench anvil and the retaining pin or ring is secure 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 on hand ratchets or torque wrenches, as the metallurgy is not rated for that application.
