Value Collection 365-2166 Hex Rethreading Die 2-1/4-12

Product Description

The VALUE COLLECTION 365-2166 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. Built from carbon steel, this die handles 2-1/4-12 thread size with a right-hand thread direction conforming to the UNS thread standard. It is used by machinists, pipefitters, plumbers, and maintenance technicians to chase and clean threads on bolts, studs, pipe fittings, and threaded rod without full thread removal. The hex body allows a standard wrench or die stock to drive the tool efficiently across a range of field and shop applications.

This rethreading die suits maintenance and repair operations where existing fasteners or threaded pipe connections have been damaged by corrosion, impact, or cross-threading. It is appropriate for use in plumbing, industrial maintenance, and mechanical assembly environments where 2-1/4-12 UNS right-hand threaded components are present. The single-piece package makes it a straightforward stock item for tool cribs and service vans.

Key Features

• 2-1/4-12 thread size restores coarse external threads on large-diameter fasteners and fittings
• Right-hand thread direction matches the most common fastener convention
• Carbon steel construction provides the hardness needed for thread chasing on steel and iron components
• Hex body design accepts standard wrenches and die stocks for controlled torque application
• UNS thread standard compliance ensures dimensional accuracy on unified national special threads

Compatibility

Designed as an OEM-style replacement rethreading die for 2-1/4-12 UNS right-hand threaded external thread applications in general industrial and mechanical service.

Installation Notes

This die is installed and operated by machinists, pipefitters, or maintenance technicians using a properly sized die stock or wrench. Before use, clean the damaged thread area and apply cutting oil to reduce heat and extend die life. Do not force the die over severely deformed threads in a single pass; use light progressive passes to avoid cracking or stripping the die. Follow applicable shop safety practices and wear appropriate hand protection when handling sharp threaded components.
