Value Collection 365-1178 Hex Rethreading Die 1-5/16-8

Product Description

The VALUE COLLECTION 365-1178 is a hex rethreading die designed to restore damaged or corroded external threads on fasteners, bolts, and threaded rod. The die cuts a 1-5/16-8 thread profile following the UNS (Unified National Special) standard and is manufactured from carbon steel for reliable hardness and wear resistance. At 1 inch thick, this die provides stable thread engagement during rethreading operations. It is a right-hand die, compatible with standard die stocks and rethreading die holders. Maintenance technicians, plumbers, pipefitters, and general machinists use this type of die when field repairs require thread restoration without full part replacement.

This rethreading die is suited for use in industrial maintenance, mechanical repair shops, and field service applications where large-diameter coarse-thread fasteners need to be cleaned up or restored. The 1-5/16-8 size is commonly encountered on heavy equipment, pipe fittings, structural fasteners, and machinery components. It is intended for hand-driven operation using a compatible hex die stock or rethreading wrench. The single-piece carbon steel construction withstands the torque demands of rethreading without deforming under normal operating loads.

Key Features

• 1 inch thick body offers stable engagement and consistent thread cutting
• Hex outer profile fits standard die stocks for hand operation

Compatibility

Designed as an OEM-style replacement or standard tooling addition for use with hex die stocks sized for large-diameter rethreading dies following UNS thread standards.

Installation Notes

This die is installed into a compatible hex die stock prior to use. Ensure the fastener or rod being rethreaded is secured and free of debris before starting. Apply cutting oil to the die and workpiece to reduce heat and extend die life during the rethreading pass. Work slowly and back off periodically to clear chips and avoid binding.
