Eagle Cutting Tool CHD-3125-24-I 5/16-24 Nf Hex Rethread Die

Product Description

The EAGLE CUTTING TOOL CHD-3125-24-I is a carbon steel hex rethread die designed to restore damaged or corroded external threads to their original specification. Built to the 5/16-24 NF (National Fine) thread standard, this die fits standard hex die stocks and tap-and-die wrenches used by plumbers, pipefitters, HVAC technicians, and maintenance trades. Rethreading dies like this one are the right tool when a fastener or fitting has thread damage that makes assembly difficult or impossible without full replacement of the threaded component. The hex body provides a secure grip in the die stock for controlled cutting.

This die is suited for field and shop use wherever 5/16-24 NF threads appear on bolts, rods, fittings, or threaded hardware. Common applications include restoring threads on mechanical fasteners, equipment mounting hardware, and threaded pipe accessories in light commercial and residential service work. It is an import-grade tool appropriate for intermittent service and general trade use where a cost-effective rethreading solution is needed.

Key Features

• 5/16-24 NF thread form for National Fine external thread restoration
• Hex body profile fits standard hex die stocks for controlled torque application
• Carbon steel construction suitable for threading mild steel and similar materials
• Import-grade option for cost-effective, intermittent-use rethreading work

Compatibility

Designed for use with standard hex die stocks that accept the appropriate hex die size. Intended for rethreading 5/16-24 NF external threads on mild steel fasteners and hardware components.

Installation Notes

This die is installed and operated by licensed tradespeople or qualified technicians familiar with threading tools. Before rethreading, clean the damaged threads of debris, rust, and grease, and apply cutting oil to the die and workpiece to reduce friction and extend die life. Secure the workpiece firmly before engaging the die stock, and advance the die slowly with consistent pressure to avoid thread misalignment. Do not use on hardened steel or stainless alloys, as carbon steel dies are not rated for those materials.
