Value Collection 365-1068 Hex Rethreading Die 7/8-20 Unef

Product Description

The VALUE COLLECTION 365-1068 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. It cuts a 7/8-20 UNEF (Unified Extra Fine) thread profile with a right-hand direction. Carbon steel construction provides the hardness needed to chase and clean threads on common fastener materials encountered in mechanical, HVAC, plumbing, and electrical work. The hex body form allows a standard wrench or die stock handle to drive the tool efficiently. This die is a practical addition to any field technician or shop mechanic's thread repair kit.

This rethreading die is suited for restoring 7/8-20 UNEF right-hand external threads on bolts, studs, fittings, and threaded rod in residential and commercial service applications. It is commonly used by HVAC technicians, plumbers, electricians, and general mechanics who encounter thread damage during equipment removal, installation, or repair. The 7/8-20 UNEF pitch is found in precision mechanical assemblies and specialty fastener applications where a fine thread engagement is required.

Key Features

• 7/8-20 UNEF thread size restores fine-pitch external threads to original specification
• Right-hand thread direction matches standard fastener convention
• Carbon steel construction delivers hardness suitable for chasing threads on typical fastener materials
• Hex body form accepts standard wrenches or die stock handles for controlled torque application
• Compact, single-piece design suited for field service and shop use

Compatibility

Designed as a rethreading die for 7/8-20 UNEF right-hand external threads on bolts, studs, and threaded components in standard mechanical assemblies.

Installation Notes

Thread repair dies are typically used by machinists, mechanics, and trade technicians working on threaded fasteners and fittings. Always de-energize, depressurize, or shut off the relevant system before attempting thread repair on installed components. Apply appropriate cutting oil to the die and the workpiece to reduce friction and extend tool life. Run the die slowly and back off periodically to clear chips and prevent binding.
