Irwin 6959 Hex Rethreading Die M18x1.5 Carbon Steel

Product Description

The IRWIN 6959 is a hex rethreading die designed to restore damaged or corroded external metric fine threads on fasteners, bolts, and fittings. Sized for M18x1.5 thread specifications with a right-hand thread direction, this die conforms to metric fine standards and is machined from carbon steel for durability under shop and field conditions. The 1-7/16 inch hex body seats securely in a standard rethreading die stock or wrench for controlled turning. It is a single-piece tool suited for use by mechanics, plumbers, HVAC technicians, and general maintenance trades who need to recover fastener threads without full replacement.

This rethreading die is appropriate for field service and bench work wherever M18x1.5 metric fine threaded fasteners appear, including equipment panels, pipe fittings, hydraulic components, and machinery hardware. It handles right-hand thread restoration on steel, iron, and similar ferrous substrates. The carbon steel construction holds up to repetitive use on standard fastener materials without significant edge degradation under normal rethreading loads.

Key Features

• M18x1.5 metric fine thread size for right-hand external thread restoration
• 1-7/16 inch hex body fits standard die stocks and adjustable wrenches
• Carbon steel construction provides adequate hardness for ferrous fastener rethreading
• Right-hand thread direction matches the most common fastener orientation
• Compact single-piece design for use in tight service environments

Compatibility

Designed as an OEM-style replacement rethreading die for use with standard hex die stocks accepting a 1-7/16 inch hex body and M18x1.5 metric fine thread specifications.

Installation Notes

This die is installed into a compatible hex die stock before use. Secure the workpiece or fastener before applying the die to prevent movement during rethreading. Apply cutting oil to the die and fastener threads to reduce friction and extend tool life. Always clean and inspect the damaged threads before rethreading to confirm the fastener shank is not cracked or deformed beyond recovery.
