Milwaukee Tool 49-57-5365 Hex Rethreading Die 9/16-12 Unc

Product Description

The MILWAUKEE TOOL 49-57-5365 is a hex rethreading die designed to clean and restore damaged or corroded external threads on fasteners and threaded rod. Sized for 9/16-12 UNC thread form, this die cuts right-hand threads and fits a 1-7/16 inch hex wrench or die stock for consistent torque application. Constructed from carbon steel, it delivers reliable hardness for field and shop rethreading work. At 0.17 pounds and 1/2 inch thick, it is compact enough to carry in a service bag. Mechanical contractors, electricians, and general trades use this type of die when salvaging threaded hardware rather than replacing it outright.

This rethreading die is suited for maintenance and repair tasks where fastener threads have been damaged by corrosion, cross-threading, or impact. Typical applications include restoring bolts, studs, and threaded rod in mechanical, structural, and electrical installations. The 9/16-12 UNC specification covers a common fastener size found across a wide range of industrial and construction assemblies. It is a non-adjustable, single-size die, so it is intended for the specific thread size listed and not as a general-purpose cutting die for new thread generation.

Key Features

• 9/16-12 UNC thread form for right-hand external thread restoration
• Carbon steel construction for field-use hardness and durability
• 1-7/16 inch hex drive fits standard die stocks and hex wrenches

Compatibility

Installation Notes

Rethreading dies are used by mechanics, electricians, and plumbers working with damaged fasteners. Secure the workpiece before applying the die to prevent movement during thread restoration. Apply appropriate cutting oil to reduce heat and improve thread quality. Follow applicable safety practices for hand tool use, including eye protection when clearing metal debris from restored threads.
