Import 22172 Hex Rethreading Die 12-28 Unf Right Hand

Product Description

The IMPORT 22172 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. Built from carbon steel, this die is suited for use on 12-28 UNF right-hand threads. Rethreading dies like this one are used to chase and clean existing threads rather than cut new ones, making them a fast repair solution on fasteners, fittings, and threaded rod. Licensed tradespeople in HVAC, plumbing, and electrical service regularly carry rethreading dies to recover stripped threads on equipment and hardware during field repairs, avoiding the need to source replacement hardware on the spot.

This die is intended for light repair and maintenance tasks where a 12-28 UNF right-hand external thread needs to be cleaned up without full replacement of the fastener or fitting. The hex body style allows it to be driven with a standard wrench or ratchet, making it practical for use in tight spaces typical of equipment cabinets, panels, and mechanical rooms. It is sold individually and is well-suited for inclusion in a field service toolkit.

Compatibility

Designed as an OEM-style rethreading tool for restoring 12-28 UNF right-hand external threads on fasteners, fittings, and threaded components across general mechanical and trade applications.

Installation Notes

Rethreading dies should be used by qualified tradespeople familiar with thread standards and hand tool operation. Before chasing threads on any energized equipment, de-energize and lock out the system per applicable electrical or mechanical safety codes. Apply a suitable cutting or thread lubricant to the die before use to reduce friction and improve thread quality. Do not force the die over severely deformed threads; evaluate whether full fastener replacement is the safer option.
