Century Drill and Tool NC Hex Threading Die

The Century Drill and Tool NC Hex Threading Die is a hand-threading die used to cut or restore external National Coarse (NC/UNC) threads on bolts, rods, and studs. The hex outer shape lets you turn the die with a standard wrench or a die stock. This makes it a practical choice for thread repair, fabrication, and general maintenance work. It is also called a hex rethreading die or a National Coarse thread die.

Key Features:

• National Coarse (NC/UNC) thread form for common fasteners
• Hex body for use with a wrench or die stock
• Cuts new external threads and cleans up damaged or corroded ones
• Suited to automotive, motorcycle, marine, RV, powersports, and shop repair work
• Made from hardened tool steel for durable cutting performance

Use cutting oil when threading to get cleaner threads and longer die life. It works on a range of common materials, including mild steel and other metals suited to hand threading. Available in multiple thread sizes to match your project.
