Milwaukee Tool 49-57-5360 Hex Rethreading Die 1/2-13 Unc

Product Description

The MILWAUKEE TOOL 49-57-5360 is a hex rethreading die designed to restore damaged or corroded external threads on fasteners and threaded rod. Built from carbon steel, this die handles 1/2-13 UNC right-hand threads and fits into a standard 1.0000-inch hex driver or holder for secure, non-slip engagement during use. At 0.06 pounds, it is a compact, single-piece tool suited for field repair work. Plumbers, electricians, HVAC technicians, and general tradespeople use this die when a fastener thread is too damaged to accept a nut cleanly but replacement is not practical on the job.

This rethreading die is intended for use on 1/2-13 UNC right-hand threaded fasteners including bolts, studs, and threaded rod commonly found in mechanical, electrical, and plumbing assemblies. It is part of the Hex-LOK series, which is designed for use with hex-drive tools such as impact drivers, ratchets, and T-handles. Typical applications include maintenance and repair in commercial and residential mechanical systems where fastener threads have been fouled by rust, paint, or mechanical damage.

Key Features

• Restores damaged 1/2-13 UNC right-hand external threads without full fastener replacement
• Carbon steel construction provides durability for repeated field use
• 1.0000-inch hex size fits standard hex-drive ratchets, T-handles, and impact drivers
• Hex-LOK series design locks securely into the driver to prevent slipping during thread chasing
• Non-adjustable fixed geometry ensures consistent thread profile on every pass
• Compact at 1/2-inch thickness for access in tight fastener locations

Compatibility

Designed as an OEM-style replacement die for use with standard 1.0000-inch hex drive thread restoring sets and compatible with 1/2-13 UNC threaded fasteners.

Installation Notes

Thread rethreading dies should be installed by a qualified tradesperson familiar with thread repair procedures. De-energize and de-pressurize any system before accessing fasteners on live mechanical or electrical assemblies. Apply thread cutting oil to the fastener and die before use to reduce friction and extend die life. Do not force the die onto badly deformed threads in a single pass; make multiple light passes to progressively restore the thread profile.
