Value Collection 314-1014 Round Die 4-40 Unc Hss

Product Description

The VALUE COLLECTION 314-1014 is a round threading die designed to cut external threads on bolts, screws, and round stock. Made from high-speed steel (HSS), it handles the heat and wear generated during threading operations on a range of common metals. This die cuts a 4-40 UNC right-hand thread profile and features an adjustable design that allows the cutting diameter to be fine-tuned for thread fit and to extend die life by compensating for wear. It is sized for use in a standard round die stock holder and is suited for both shop and field threading work.

This die is used in machining, maintenance, and fabrication applications where 4-40 UNC external threads are required. Typical use cases include threading small fastener stock, cleaning up damaged threads on screws, and producing custom-length threaded rods in light machine work. The 4-40 thread designation is common in instrumentation, electronics assembly, and light mechanical assemblies. Machinists, tool-and-die workers, and maintenance technicians are the primary users of this type of tooling.

Key Features

• 4-40 UNC thread profile for compatibility with standard 4-40 fastener applications
• High-speed steel construction provides heat resistance and extended cutting life
• Adjustable design allows fine-tuning of thread fit and compensation for wear
• Right-hand thread direction — the standard for the vast majority of threading applications
• Round die form fits standard round die stock holders

Compatibility

Designed as a standard round die for use in compatible round die stock holders sized for this die diameter. Intended for cutting 4-40 UNC external threads on applicable round stock and fasteners.

Installation Notes

This die is installed and secured in a round die stock holder before use — ensure the holder is the correct size for this die. Apply cutting fluid to the workpiece and die before threading to reduce heat buildup and improve thread quality. For adjustable dies, set the cutting diameter with the adjustment screw before beginning a cut, and back the die off periodically to clear chips during threading. Secure the workpiece firmly in a vise before starting.
