Eagle Cutting Tool CHD-540-I Carbon Hex Rethread Die 5-40

Product Description

The EAGLE CUTTING TOOL CHD-540-I is a carbon steel hex rethread die designed to restore damaged or corroded external threads on 5-40 threaded fasteners and fittings. The hexagonal body allows standard wrench engagement for controlled torque application, making it practical for field repairs as well as bench work. At 1.96 pounds, the die is a solid, durable tool suited for use by plumbers, HVAC technicians, electricians, and general maintenance professionals who need to salvage threaded components rather than replace them outright.

This rethread die is used when external threads on bolts, screws, pipe nipples, or fittings are crossed, corroded, or partially stripped. The 5-40 designation indicates a 5 thread form at 40 threads per inch, a fine-pitch fastener thread common in light mechanical and electrical applications. It is appropriate for both shop and field use wherever 5-40 threaded components require thread restoration without full replacement.

Key Features

• Carbon steel construction provides hardness suitable for thread chasing and restoration on standard fastener materials
• Hex body design accepts standard open-end or box wrenches for controlled application
• 5-40 thread specification for fine-pitch fastener thread restoration
• Compact, portable form factor at 1.96 pounds for field or shop use
• Rethread die extends the service life of threaded components, reducing replacement costs

Compatibility

Designed for use on 5-40 external threads on bolts, machine screws, and threaded fittings where thread restoration is required.

Installation Notes

Rethread dies should be installed by qualified tradespeople familiar with thread repair procedures. Before use, de-energize or depressurize any system containing the fastener or fitting being serviced. Apply a suitable cutting or tapping fluid to the die and the work piece to reduce friction and improve thread quality. Do not force the die onto severely deformed threads; pre-clean or file threads as needed before chasing.
