Irwin 9324 Hex Rethreading Die 8-32 Right Hand

Product Description

The IRWIN 9324 is a hex rethreading die designed to restore damaged or corroded external threads on fasteners and threaded rod. The die cuts a right-hand 8-32 Unified National Coarse (UNC) thread profile and fits a 1-inch hex holder or wrench for controlled torque during use. Constructed from carbon steel, it delivers the hardness needed to clean and recut threads on standard steel and iron fasteners. This is a single-piece die suited for maintenance technicians, plumbers, electricians, and HVAC technicians who need to restore fastener threads in the field or shop without replacing the entire fastener.

This rethreading die is used in light industrial, commercial, and residential maintenance applications where 8-32 machine screw threads have been stripped, cross-threaded, or corroded. Typical use cases include restoring threads on electrical panel screws, equipment mounting hardware, and small-diameter machine screws encountered across HVAC, plumbing, and electrical service work. The 1-inch hex drive allows use with a standard open-end wrench or hex die stock for consistent thread engagement.

Installation Notes

Rethreading dies are typically used by maintenance technicians and licensed trade professionals working on fastener repair. Before use, clean the damaged threads of debris and apply cutting oil to reduce friction and extend die life. Turn the die slowly and back off periodically to clear cuttings and prevent binding. Always verify the original thread specification before selecting the die to avoid further thread damage.
