Value Collection 367-0322 Hex Rethreading Die 1/2-20 Hss

Product Description

The VALUE COLLECTION 367-0322 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. Made from high-speed steel, it handles the heat and wear generated during rethreading operations on fasteners, fittings, and threaded rod. The die cuts a 1/2-20 UNF thread profile in the right-hand direction. It is used by HVAC technicians, plumbers, electricians, and general maintenance trades wherever bolt and fitting threads need to be cleaned up or restored rather than replaced. The hexagonal body allows a standard wrench or die holder to apply consistent torque during the cut.

This rethreading die is suited for repair work on 1/2 inch fasteners and threaded components in mechanical, plumbing, and HVAC installations. A right-hand thread pattern covers the vast majority of standard inch-series fasteners. The UNF thread standard indicates a fine-pitch profile, which is common on precision fasteners, hydraulic fittings, and certain equipment mounting hardware. Technicians reach for this die when field-damaged threads need to be chased or restored without full part replacement.

Key Features

• 1/2-20 UNF thread size for fine-pitch external thread restoration
• High-speed steel construction resists heat and wear during cutting operations
• Right-hand thread direction matches standard inch-series fastener orientation
• Hex body accepts standard wrenches and die holders for controlled torque application
• Single-piece design — no assembly required before use

Compatibility

Designed as a rethreading die for external 1/2-20 UNF right-hand threads on standard inch-series fasteners, fittings, and threaded rod.

Installation Notes

Rethreading dies are installed and operated by mechanics, pipefitters, and maintenance technicians. Before chasing threads on an assembled component, isolate or power down the system as required by the application. Use cutting oil or thread-cutting fluid to extend die life and improve cut quality. Do not force the die past resistance — back off periodically to clear chips and prevent die breakage.
