Value Collection 314-1266 Round Die 5/8-11 Unc Hss

Product Description

The VALUE COLLECTION 314-1266 is a round threading die used to cut or recut external threads on fasteners, bolts, and round stock. Made from high-speed steel, this die is built to handle the heat and wear of continuous threading work. It cuts a 5/8-11 UNC right-hand thread profile and includes an adjustable design that allows the operator to fine-tune thread fit by slightly opening or closing the die body. Licensed machinists, maintenance technicians, and experienced mechanics rely on this type of tooling for fabrication, repair, and field work.

This die is suited for threading mild steel, stainless, aluminum, and similar machinable materials at 5/8-11 UNC — a coarse-thread standard common in structural fasteners, machine bolts, and general mechanical assemblies. It is appropriate for both shop use and field repair applications where standard hex or rod stock needs a fresh thread. The adjustable feature makes it useful when cutting threads on harder materials or when a closer-tolerance fit is required on the mating nut or coupler.

Key Features

• 5/8-11 UNC thread profile — coarse-thread standard widely used in structural and mechanical fastening
• High-speed steel construction for heat resistance and extended tool life in threading operations
• Adjustable die body allows thread fit to be fine-tuned without changing tooling
• Right-hand thread direction — standard for the vast majority of fastener applications
• Round die form accepts standard die stocks and die holders

Compatibility

Designed as a standard round die compatible with die stocks and holders sized to accept round threading dies for 5/8-11 UNC external thread cutting applications.

Installation Notes

Round dies are used by machinists, maintenance mechanics, and skilled tradespeople using a die stock or die holder. Secure the workpiece firmly before threading and apply cutting oil to reduce heat and improve thread quality. Start the die square to the workpiece to avoid cross-threading. Adjustable dies should be set to the full open position before beginning a cut, then adjusted incrementally for final thread fit.
