Proto J10014SS Impact Socket 1 in Drive 7/8 in 4-point

Product Description

The PROTO J10014SS is a 4-point impact socket designed for heavy-duty fastener removal and installation using a 1 inch square drive. Built to handle the high-torque output of pneumatic and hydraulic impact wrenches, it fits a 7/8 inch fastener and measures 2.5 inches in overall length. The 4-point drive configuration concentrates force on the flat surfaces of the fastener, making it a reliable choice in demanding industrial and mechanical service environments. Licensed mechanics, millwrights, and maintenance technicians are the primary users. At 1.52 pounds, the socket is built with the mass and material integrity expected in professional-grade impact tooling.

This socket is suited for heavy equipment maintenance, structural assembly, and industrial machinery service where a 1 inch drive impact wrench is the standard tool. The 7/8 inch size covers fasteners common in hydraulic fittings, structural bolting, and large-frame mechanical assemblies. It is appropriate for both shop and field use wherever controlled high-torque fastening or loosening is required.

Key Features

• 1 inch square drive accepts standard heavy-duty impact wrenches
• 7/8 inch socket size for large-frame fastener applications
• 4-point drive geometry for concentrated torque transfer on fastener flats
• 2.5 inch overall length for reach in typical heavy equipment access points
• 1.52 pound construction indicating solid, impact-rated wall thickness

Compatibility

Designed as an OEM-style replacement impact socket compatible with 1 inch drive impact wrenches in heavy industrial and mechanical service applications.

Installation Notes

Installation and removal should be performed by qualified mechanics or millwrights familiar with impact tooling. Always confirm the drive tool is set to the correct torque direction before engaging the fastener. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Do not use impact sockets with standard ratchets or torque wrenches, as impact-rated sockets are not designed for that loading profile.
