Titan Usa TE80544 Hex Rethreading Die 3/8-16 Unc

Product Description

The TITAN USA TE80544 is a hex rethreading die designed to restore damaged or corroded external threads on fasteners, bolts, and threaded rod. It accepts a 3/8-16 Unified National Coarse (UNC) thread profile and cuts in the right-hand direction. The die measures 3/8 inches thick with a 25/32-inch hex profile for use with a standard open-end wrench or die stock. Machined from carbon steel, it delivers the hardness needed to chase and re-form steel fastener threads without deforming the cutting edges under normal shop or field use. Plumbers, pipefitters, HVAC technicians, and electricians keep rethreading dies in their service kits to recover field-damaged fasteners without full replacement.

This die is suited for maintenance and repair work across residential and light commercial applications wherever 3/8-16 UNC fasteners are used. Common scenarios include restoring threads on equipment mounting bolts, conduit fittings, pipe flange hardware, and structural fasteners that have been exposed to corrosion, impact, or cross-threading. The compact hex body allows the die to be driven with a wrench in tight spaces where a full die stock handle cannot fit, making it practical for in-place fastener recovery on installed equipment.

Key Features

• 3/8-16 UNC thread profile restores standard right-hand external threads
• Carbon steel construction provides cutting hardness for steel fastener recovery
• 25/32-inch hex body drives with a standard open-end wrench or adjustable wrench
• 3/8-inch thickness keeps the die compact for use in confined spaces
• Right-hand thread direction matches the vast majority of standard fastener applications
• Series 795 single-piece hex die — no die stock required

Compatibility

Designed for use on 3/8-16 UNC right-hand external threads on steel fasteners, bolts, and threaded rod in mechanical, HVAC, plumbing, and electrical service applications.

Installation Notes

Rethreading dies are typically used by hand or with a wrench — no power tools are required and are generally not recommended, as controlled torque prevents die damage and thread gouging. Before chasing threads, remove loose rust, debris, and burrs from the fastener with a wire brush. Apply cutting oil to the die and fastener prior to use to reduce heat and extend die life. Ensure the fastener is secured or the equipment is de-energized and de-pressurized before performing any thread repair on installed components.
