Milwaukee Tool 49-57-5362 Hex Rethreading Die 1/2-20 Unf

Product Description

The MILWAUKEE TOOL 49-57-5362 is a hex rethreading die designed to restore damaged or corroded external threads on fasteners and threaded rod. It cuts a 1/2-20 UNF right-hand thread profile and fits the Hex-LOK series, which accepts the die in a 1.0000-inch hex holder. The body is machined from carbon steel for durability under repeated use. At 0.06 pounds, the die is compact and lightweight, making it easy to carry in a service bag or toolbox. Licensed tradespeople and maintenance technicians use this die to recondition bolt and stud threads on the job without removing the fastener from the assembly.

This rethreading die is suited for mechanical, plumbing, and electrical trade applications where fastener threads are stripped, rusted, or otherwise damaged and replacement is not practical. It is used on 1/2-20 UNF threaded fasteners in residential and light commercial settings. The Hex-LOK series design allows the die to be driven with a standard wrench or driver equipped with the matching hex holder, speeding up rethreading tasks compared to traditional round-stock die stocks.

Key Features

• 1/2-20 UNF thread profile restores fine-pitch external threads to spec
• Carbon steel construction provides strength for rethreading hardened fasteners
• 1.0000-inch hex body fits Hex-LOK series holders for wrench or driver use
• Right-hand thread direction matches standard fastener orientation
• Non-adjustable design maintains consistent thread geometry
• 0.50-inch thickness keeps the die compact for tight-access work

Compatibility

Designed for use with the MILWAUKEE TOOL Hex-LOK series die stock system accepting a 1.0000-inch hex die body. Intended for 1/2-20 UNF right-hand threaded fasteners.

Installation Notes

Rethreading dies are typically used by licensed tradespeople or experienced mechanics. Before rethreading, clean the fastener of debris, rust, and old thread compound using a wire brush, and apply cutting oil to reduce heat and extend die life. Drive the die slowly with steady, even pressure, reversing periodically to clear chips. Never force the die past significant resistance, as this can crack the die or further damage the fastener thread.
