Value Collection 367-0561 Hex Rethreading Die 7/8-9 Hss Unc

Product Description

The VALUE COLLECTION 367-0561 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. Sized for 7/8-9 thread geometry, it conforms to the Unified National Coarse (UNC) standard and cuts in a right-hand direction. The die is manufactured from high-speed steel (HSS), which provides the hardness and wear resistance needed to rethread fasteners made from mild steel, iron, and similar materials. Weighing 0.5 pounds, it is compact enough for use in the field or on the bench. Machinists, maintenance technicians, and general tradespeople use this type of die when bolt or rod threads are stripped, galled, or rusted beyond reliable use.

This rethreading die is suited for maintenance and repair work across industrial, commercial, and mechanical service environments. It is appropriate for restoring threads on bolts, studs, and threaded rod in applications such as structural fastening, equipment maintenance, and pipefitting where 7/8-9 UNC fasteners are common. The hex outer profile allows the die to be driven with a standard wrench or die stock for controlled thread restoration.

Key Features

• 7/8-9 UNC thread specification for restoration of coarse-pitch external threads
• Right-hand thread direction matches standard fastener orientation
• High-speed steel construction provides hardness and extended cutting life
• Hex body profile accepts a standard wrench or die stock for positive drive
• Single-piece solid construction with no adjustable components

Compatibility

Designed for rethreading 7/8-9 UNC right-hand external threads on bolts, studs, and threaded rod in maintenance and repair applications.

Installation Notes

Apply cutting oil or thread-cutting lubricant to the workpiece before use to reduce heat buildup and extend die life. Secure the workpiece firmly before engaging the die to prevent movement during cutting. Start the die squarely on the thread axis to avoid cross-threading. This operation does not require electrical power, but appropriate eye protection and gloves should be worn when handling metal shavings.
