Proto J10030L Impact Socket 1 in Drive 1-7/8 in 6-point

Product Description

The PROTO J10030L is a 1-inch drive, 6-point impact socket designed for heavy-duty fastener work in industrial, mechanical, and construction environments. Built with a hex drive style, this socket accepts 1-7/8 inch fasteners and measures 4.25 inches in overall length. The 6-point geometry concentrates drive force on the flats of the fastener, reducing the risk of rounding under high-torque conditions. At 3.92 pounds, the J10030L is built for sustained use on impact wrenches in demanding applications where socket integrity and dimensional accuracy are critical.

This socket is suited for heavy equipment maintenance, structural steel assembly, industrial machinery repair, and fleet service operations where large-diameter fasteners are common. The 1-inch drive size is standard in high-torque impact applications found in commercial and industrial settings. Licensed mechanics, ironworkers, and maintenance technicians working on large bolted assemblies are the typical users. The 4.25-inch overall length provides adequate reach for recessed or partially obstructed fastener locations without requiring an extension in many standard configurations.

Key Features

• 1-inch drive size rated for high-torque impact wrench use
• 1-7/8 inch socket size fits large-diameter hex fasteners
• 6-point drive geometry reduces fastener rounding under load
• Hex drive style for positive engagement on standard hex fasteners
• 4.25-inch overall length accommodates recessed fastener positions

Compatibility

Designed as an OEM-style impact socket for use with 1-inch drive impact wrenches and drive tools in industrial and heavy-duty mechanical service applications.

Installation Notes

This socket is intended for use by qualified mechanics and maintenance technicians operating 1-inch drive impact wrenches. Always confirm the socket is fully seated on the drive anvil and that the retaining pin or ring is engaged 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, as impact-grade sockets are not designed for that application.
