Cle-line C65881 Round Die 9/16-12 Unc Hss Adjustable

Product Description

The CLE-LINE C65881 is a round threading die designed to cut external threads on rod, bolt stock, and fastener blanks. It produces a 9/16-12 UNC right-hand thread profile and is manufactured from high-speed steel for durability through repeated cuts in ferrous and non-ferrous materials. At 0.5 inches thick, it fits standard round die stocks sized for 9/16-inch tooling. The adjustable design allows the operator to fine-tune thread fit and compensate for tool wear, extending the usable service life of the die. Machinists, pipefitters, and maintenance technicians use this type of die for production threading and field repair work.

This die is suited for threading operations on mild steel, aluminum, brass, and similar workpiece materials where a 9/16-12 UNC external thread is required. Typical applications include fabricating threaded rod, chasing damaged threads on fasteners, and creating new threaded ends on bar stock. The UNC thread standard makes this a common choice in general industrial, mechanical, and maintenance-repair-operations settings where inch-series fasteners are standard.

Key Features

• 9/16-12 UNC thread size for inch-series external threading
• High-speed steel construction for heat resistance and edge retention
• Adjustable design allows thread fit fine-tuning and compensates for wear
• Right-hand thread direction matches standard fastener convention
• 0.5 inch thickness fits standard round die stocks for this size range

Compatibility

Designed as an OEM-style replacement or working die for use in standard round die stocks sized to accept dies for 9/16-inch thread cutting.

Installation Notes

Round dies are installed and secured in a die stock handle before use. Ensure the die stock set screw engages the adjustment slot properly before threading begins. Apply cutting oil to the workpiece to reduce heat and extend die life. Always de-burr the leading end of the workpiece and chamfer it slightly to allow the die to start cleanly.
