Cle-line C65844 Round Die 5/16-18 Unc Hss Adjustable

Product Description

The CLE-LINE C65844 is a round threading die designed to cut external threads on bolts, studs, and rod stock. Made from high-speed steel (HSS), it is built to handle the heat and wear of repetitive threading operations in production and maintenance environments. The die cuts a 5/16-18 UNC right-hand thread and measures 0.5 inches in thickness. The adjustable design allows the technician to fine-tune thread fit and compensate for minor wear over the life of the die. This die is used by machinists, pipefitters, maintenance mechanics, and tool-and-die tradespeople working in fabrication, repair, and field service applications.

The C65844 is suited for threading mild steel, aluminum, and similar ferrous and non-ferrous materials in shop or field settings. The 5/16-18 UNC specification makes it appropriate for standard fastener production and repair work where a coarse-thread unified national series profile is required. It fits standard round die stocks sized for the appropriate die outside diameter in the 0710 series. Machinists and mechanics performing bolt repair, custom fastener fabrication, or thread restoration will find this die appropriate for low-to-moderate volume threading tasks.

Key Features

• High-speed steel construction for heat resistance and extended die life under continuous use
• 5/16-18 UNC thread specification for standard coarse-thread fastener applications
• Adjustable design allows thread fit tuning and die life extension
• Right-hand thread direction for standard fastener orientation
• 0.5 inch thickness fits standard 0710 series round die stocks
• Series 0710 designation for straightforward replacement and stock matching

Compatibility

Designed for use with standard round die stocks accommodating the 0710 series die outside diameter. Verify die stock compatibility by confirming the die outer diameter matches the holder before use.

Installation Notes

Round dies are installed and secured in a matching die stock by a machinist or qualified mechanic. Ensure the die is seated squarely in the holder and the set screws are tightened before threading. Apply cutting oil to the workpiece and die to reduce friction, extend die life, and produce a cleaner thread profile. Inspect the die for cracks or chipped cutting edges before each use and replace if damaged.
