Value Collection 365-3162 Hex Rethreading Die 3-1/8-8

Product Description

The VALUE COLLECTION 365-3162 is a hex rethreading die designed to restore damaged or corroded external threads on fasteners, pipe fittings, and threaded rod. It cuts a 3-1/8-8 UNS right-hand thread profile and is built from carbon steel for reliable performance in shop and field applications. The die measures 2 inches thick and features a 5-inch hex outer dimension for use with a standard die stock or wrench. Machinists, pipefitters, and maintenance technicians reach for this tool when threads need to be cleaned up or re-cut without full part replacement.

This rethreading die is suited for industrial maintenance, mechanical repair, and fabrication environments where large-diameter UNS threads are encountered. Typical applications include restoring threads on heavy equipment fasteners, large-diameter pipe fittings, and structural threaded components. The right-hand thread direction matches the most common fastener orientation in industrial assemblies. The 3-1/8-8 thread designation indicates a 3-1/8 inch nominal diameter with 8 threads per inch.

Key Features

• 3-1/8-8 UNS thread profile for large-diameter rethreading work
• Right-hand thread direction compatible with standard fastener orientation
• Carbon steel construction provides hardness suitable for rethreading steel and iron fasteners
• 5-inch hex outer dimension fits standard large die stocks or adjustable wrenches
• 2-inch thickness provides added tool stability and thread engagement during use

Compatibility

Designed for use with die stocks or wrenches sized to accept a 5-inch hex drive. Intended for rethreading external threads conforming to the 3-1/8-8 UNS thread standard.

Installation Notes

Rethreading dies are typically used by machinists, pipefitters, and industrial maintenance technicians. Secure the workpiece firmly before applying the die to prevent movement during thread cutting. Apply appropriate cutting oil to reduce heat and extend die life. Inspect the die for wear or chipping before each use and replace if the cutting edges are damaged.
