Milwaukee Tool 49-57-5369 Hex Rethreading Die 5/8-11 Unc

Product Description

The MILWAUKEE TOOL 49-57-5369 is a hex rethreading die designed to clean and restore damaged or corroded external threads without removing the fastener or workpiece from service. Built from carbon steel, it handles 5/8-11 UNC right-hand threads and fits a 1-7/16 inch hex wrench or socket for quick, controlled torque application. At 0.17 pounds and a 1/2 inch thickness, the die is compact enough to carry in a service bag and sized for single-hand operation in tight quarters. It is intended for use by mechanics, ironworkers, pipefitters, and maintenance technicians who need to recover threads in the field or on the bench without a full threading set.

This die is suited for restoration work on 5/8-11 UNC fasteners commonly found in structural connections, mechanical assemblies, and heavy equipment. The non-adjustable design keeps thread geometry consistent pass after pass, making it a reliable grab-and-go tool for shops and field crews. The standard UNC thread profile covers the widest range of inch-series fastener stock encountered in general industrial and construction applications.

Key Features

• 5/8-11 UNC thread size restores one of the most common inch-series coarse-thread fastener diameters
• Carbon steel construction provides hardness suitable for rethreading mild steel and similar fastener materials
• Right-hand thread direction matches standard UNC fastener orientation for direct drive-on use
• 1-7/16 inch hex drive accepts a standard wrench or socket for controlled torque without specialty tooling
• Non-adjustable fixed profile ensures consistent thread form on every pass
• Compact 1/2 inch thickness fits confined spaces and tool pouches

Compatibility

Designed as an OEM-style replacement or supplemental die for Milwaukee rethreading die sets compatible with 5/8-11 UNC external threads. Verify hex drive size and thread specification against your existing set before ordering.

Installation Notes

Rethreading dies are typically installed and operated by mechanics, maintenance technicians, or ironworkers following standard thread-restoration procedures. Before use, ensure the fastener or stud is secured and that any powered equipment is de-energized or locked out per applicable OSHA lockout/tagout procedures. Apply cutting oil to the die and workpiece threads to reduce friction and extend die life. Do not force the die over severely deformed threads in a single pass; make incremental passes to avoid stripping the workpiece.
