Milwaukee Tool 49-57-5366 Hex Rethreading Die 14mm

Product Description

The MILWAUKEE TOOL 49-57-5366 is a hex rethreading die designed to restore damaged or corroded external metric fine threads without replacing the fastener or fitting. Machined from carbon steel, this die handles right-hand thread direction and is sized for 14mm metric fine thread. The 1-7/16 inch hex body seats securely in a standard die stock or wrench, allowing controlled hand pressure during rethreading. Non-adjustable construction keeps the thread profile fixed and consistent pass after pass. Plumbers, pipefitters, HVAC technicians, and millwrights keep these dies on hand for field repair work where replacing a threaded rod or stud is impractical.

This rethreading die is suited for maintenance, repair, and overhaul work on metric fine-threaded fasteners and components in both residential and light commercial settings. Typical applications include restoring threads on bolts, studs, and pipe fittings that have been damaged by corrosion, cross-threading, or mechanical wear. The compact 1/2 inch thickness allows access in tighter spaces than full-depth threading dies.

Key Features

• Carbon steel construction for durability across repeated rethreading passes
• Metric fine thread standard, 14mm thread size, right-hand direction
• 1-7/16 inch hex body fits standard die stocks and adjustable wrenches
• Non-adjustable design maintains consistent thread profile
• 1/2 inch thickness for access in confined work areas

Compatibility

Designed for use with standard 1-7/16 inch hex die stocks compatible with metric fine 14mm right-hand thread applications.

Installation Notes

Rethreading dies are installed by a qualified tradesperson using an appropriate die stock or wrench sized to the hex dimension. Before rethreading, clean the damaged fastener of debris, rust, and old lubricant, and apply a thread cutting oil to reduce friction and extend die life. Never force the die past resistance — back off a quarter turn periodically to clear chips. Follow applicable facility lockout/tagout procedures before performing thread repair on any component still connected to a system under load or pressure.
