Value Collection 364-0391 Hex Rethreading Die M39x2

Product Description

The VALUE COLLECTION 364-0391 is a hex rethreading die designed to restore damaged or corroded external metric fine threads on bolts, studs, and threaded rod. It carries an M39x2 thread size and cuts in a right-hand direction, making it the correct choice for standard metric fastener repair work. The die body is 1 inch thick and constructed from carbon steel, providing the rigidity needed to chase and restore threads without deforming the cutting edges under normal shop use. Licensed machinists, millwrights, pipefitters, and maintenance mechanics reach for rethreading dies when field-damaged fasteners need to be salvaged rather than replaced.

This die is suited for repair and maintenance applications in industrial, commercial, and heavy-equipment environments where large-diameter M39 metric fine fasteners are common. Typical scenarios include restoring thread integrity on hydraulic cylinder rods, large structural bolts, shaft ends, and machinery anchor studs. The hex body allows a standard die stock or adjustable wrench to drive the die with controlled torque, which is especially useful in tight or awkward service positions.

Key Features

• M39x2 metric fine thread size for large-diameter fastener repair
• Right-hand thread direction matches standard metric fastener convention
• 1 inch thick carbon steel body resists flex and distortion during use
• Hex outer profile accepts standard die stocks and wrenches
• Metric fine thread standard for precise thread pitch restoration

Compatibility

Designed as an OEM-style rethreading die for use on M39x2 metric fine right-hand external threads on bolts, studs, and threaded rod in industrial and mechanical maintenance applications.

Installation Notes

Rethreading dies should be installed and driven by a qualified machinist or maintenance mechanic familiar with thread repair procedures. Lubricate the fastener and die with a suitable cutting oil before use to reduce heat and extend die life. Ensure the die is started square to the thread axis to avoid cross-threading or die damage. Always secure the workpiece before applying torque to the die stock.
