Milwaukee Tool 49-57-5315 Hex Rethreading Die 6-32 Unc

Product Description

The MILWAUKEE TOOL 49-57-5315 is a hex rethreading die designed to restore damaged or corroded external threads on fasteners and threaded rod. Built from carbon steel, this die delivers the hardness needed to clean and recut 6-32 UNC threads without deforming the workpiece. The hex body measures 1 inch across flats and 0.5 inches thick, allowing it to seat securely in a standard wrench or die holder for consistent torque transfer. Right-hand thread direction matches the most common fastener orientation in mechanical and electrical assemblies. It is part of the Hex-LOK series and is a non-adjustable, single-size tool intended for precision thread restoration work.

This die is suited for use by electricians, HVAC technicians, plumbers, and general maintenance tradespeople who regularly encounter thread damage on small-diameter fasteners in control panels, equipment enclosures, and mechanical assemblies. The 6-32 UNC thread size is common in sheet metal screws, terminal board hardware, and light fixture mounting hardware. It is appropriate for both shop bench work and field service repairs where a fastener must be reused or a threaded fitting must be restored to spec before reassembly.

Key Features

• 6-32 UNC thread size for right-hand external thread restoration
• Carbon steel construction provides hardness for clean thread recutting

• Non-adjustable design ensures consistent thread form on every pass
• Hex-LOK series for positive grip and reduced slip during use

Compatibility

Designed as an OEM-style rethreading die for use with standard 1 inch hex die holders and wrenches compatible with 6-32 UNC external thread profiles.

Installation Notes

Rethreading dies are installed by licensed tradespeople and qualified maintenance technicians. Before use, ensure the workpiece is secured and the damaged thread area is clean and free of debris. Apply cutting oil to the die and the fastener before making contact to reduce friction and extend die life. Do not force the die over badly deformed threads in a single pass; make incremental passes to avoid fracturing the carbon steel.
