Proto J10060L Impact Socket 1 in Drive 3-3/4 in 6-point

Product Description

The PROTO J10060L is a heavy-duty impact socket designed for use with 1 inch drive impact wrenches and rattle guns. Built from alloy steel, it delivers the torsional strength needed to handle high-torque fastener removal and installation in demanding shop and field environments. The socket measures 3-3/4 inches across the hex opening and features a 6-point drive geometry for maximum contact on fastener flats. Overall length is 6-1/4 inches. This socket is used by mechanics, industrial maintenance technicians, and heavy equipment service professionals who work with large-format fasteners on a daily basis.

The J10060L is suited for heavy equipment maintenance, truck fleet service, agricultural machinery repair, and industrial assembly applications where a 1 inch drive impact tool is the standard. The 6-point hex profile reduces the risk of fastener rounding under high torque, making it appropriate for rusted, seized, or high-load fasteners. At 18.47 pounds, this is a substantial piece of tooling intended for stationary or mobile shop use rather than light-duty hand-tool work.

Key Features

• 1 inch square drive compatible with heavy-duty impact wrenches
• 3-3/4 inch hex socket opening for large-format fasteners
• 6-point drive geometry maximizes contact area and reduces fastener rounding
• Alloy steel construction rated for impact use
• 6-1/4 inch overall length provides clearance in deep or recessed fastener applications

Compatibility

Designed for use with 1 inch drive impact wrenches and torque multipliers. Compatible with standard 1 inch drive detent or hog-ring retention systems common to heavy-duty impact tools.

Installation Notes

Install and remove using a 1 inch drive impact wrench or breaker bar. Confirm the retaining pin or hog ring is fully seated before applying torque. Inspect the socket for cracks or deformation before each use, as impact sockets can develop stress fractures under repeated high-torque cycling. Never use an impact socket with a standard hand-drive ratchet in place of a proper impact tool.
