Eagle Cutting Tool CHD-3125-18-I 5/16-18 Nc Hex Rethread Die

Product Description

The EAGLE CUTTING TOOL CHD-3125-18-I is a carbon steel hex rethread die designed to restore damaged or corroded external threads on 5/16 inch-18 NC (National Coarse) fasteners and threaded rod. The hexagonal body allows for easy engagement with a standard wrench or die stock for controlled torque application. This die is well suited for field repair and shop use by plumbers, HVAC technicians, electricians, and general maintenance trades who need a fast way to clean up or restore threads without replacing the fastener entirely.

This rethread die is appropriate for use on 5/16 inch-18 NC threaded bolts, studs, and rods commonly found in mechanical systems, pipe hangers, equipment mounting hardware, and structural fasteners. It is a practical addition to any service van or shop toolbox where thread repair tasks arise on residential and light commercial work. The hex body format makes it compatible with standard open-end wrenches and adjustable wrenches, eliminating the need for a dedicated die handle.

Installation Notes

Thread repair dies should be applied to the fastener by hand-starting the die straight onto the thread axis before applying wrench torque to avoid cross-threading. Back the die off periodically to clear metal chips, especially on corroded fasteners. No power tools should be used to drive this die. Wear appropriate hand and eye protection when performing thread repair operations.
