Proto J15058 Impact Socket 1-1/2 in Drive 3-5/8 in 6-point

Product Description

The PROTO J15058 is a heavy-duty impact socket designed for high-torque fastening and removal applications. Built around a 1-1/2 inch drive, it accepts a 3-5/8 inch hex fastener and features a 6-point contact geometry that concentrates force on the flat faces of the fastener rather than the corners. This reduces the risk of rounding under heavy impact loads. The overall length is 5 inches. The socket is intended for use with 1-1/2 inch drive impact wrenches in industrial, heavy equipment, and large-scale mechanical service environments. Licensed mechanics, millwrights, and heavy-equipment technicians are the primary installers.

This socket is suited for industrial maintenance, fleet service, construction equipment repair, and any application requiring a large-format hex drive interface. Its 6-point design makes it appropriate for high-torque removal of large fasteners on equipment such as industrial machinery, heavy trucks, and structural assemblies. The 1-1/2 inch drive size places this socket in the heavy-duty tier, typically used with pneumatic or hydraulic impact tools rated for that drive class.

Key Features

• 1-1/2 inch drive size for use with large-format impact wrenches
• 3-5/8 inch socket opening sized for large hex fasteners
• 6-point contact geometry reduces corner rounding under impact load
• 5 inch overall length provides clearance in deep or recessed fastener applications
• Hex drive style for direct engagement on standard hex-head fasteners

Compatibility

Designed for use with 1-1/2 inch drive impact wrenches and ratchets in heavy-duty industrial and mechanical service applications.

Installation Notes

Installation and removal should be performed by qualified mechanics or millwrights using a properly rated 1-1/2 inch drive impact tool. Ensure the socket is fully seated on both the drive tool and the fastener before applying torque. Inspect the socket for cracks or deformation before each use, and never use impact sockets with hand-drive ratchets in high-torque scenarios. Follow all applicable workplace safety standards when operating impact tools in industrial environments.
