Proto J15044 Impact Socket 1-1/2 in Drive 2-3/4 in 6-pt

Product Description

The PROTO J15044 is a heavy-duty impact socket designed for high-torque fastening applications in industrial, mechanical, and maintenance environments. Built around a 1-1/2 inch drive, this socket accepts 2-3/4 inch hex fasteners and features a 6-point contact geometry that maximizes surface contact on fastener flats to reduce rounding under load. The overall length of 4-1/4 inches provides adequate clearance for recessed fastener applications. It is intended for use with 1-1/2 inch drive impact wrenches and is suited for licensed mechanics, millwrights, and heavy equipment technicians working on large-scale machinery, structural assemblies, and industrial equipment.

This socket is appropriate for heavy commercial and industrial applications where large-format fasteners are common. Typical use cases include heavy equipment assembly, fleet maintenance, structural steel work, and large pump or compressor servicing. The 6-point hex drive design makes it well-suited for turning large bolts and nuts that require a controlled, high-torque input without slipping. It is a single-piece socket packaged individually.

Key Features

• 1-1/2 inch drive size for use with large impact wrenches
• 2-3/4 inch socket opening fits large hex fasteners
• 6-point contact geometry reduces fastener rounding under high torque
• 4-1/4 inch overall length for access in recessed or flanged applications
• Hex drive style ensures positive engagement on standard hex fasteners

Compatibility

Designed for use with 1-1/2 inch drive impact wrenches and compatible with 2-3/4 inch hex fasteners in heavy industrial and commercial applications.

Installation Notes

Installation and use should be performed by qualified mechanics or technicians familiar with large-drive impact tooling. Always ensure the socket is fully seated on both the drive and the fastener before applying torque. Inspect the socket for cracks or wear before each use, and never use impact sockets with hand-drive ratchets. Follow applicable equipment manufacturer torque requirements for the fastener being driven.
