Value Collection 315-1206 Round Die 1/2-16 Uns Hss

Product Description

The VALUE COLLECTION 315-1206 is a round threading die machined from high-speed steel (HSS) for cutting external threads on rod, bolt blanks, and round stock. It produces a 1/2-16 UNS right-hand thread and features an adjustable design that allows the cutting diameter to be fine-tuned for fit tolerance or thread class. High-speed steel construction maintains cutting edge hardness under the heat generated during threading operations, making this die suitable for production and maintenance use in machine shops, fabrication environments, and field repair applications.

This die is used wherever a 1/2-16 UNS external thread must be cut or restored. The UNS (Unified National Special) thread standard covers non-standard thread pitches not found in the UNC or UNF series, making this die the correct choice when a 16-TPI pitch is required on a 1/2-inch diameter fastener or stud. Typical applications include custom fastener fabrication, stud replacement, and repair of non-standard threaded assemblies. It is installed in a standard round die stock holder sized for the die body diameter.

Key Features

• High-speed steel construction resists heat and wear during threading cuts
• Adjustable design allows fine-tuning of cutting diameter for thread fit
• Right-hand thread direction — standard orientation for most fastener applications
• 1/2-16 UNS thread specification for non-standard pitch applications
• Single-piece die ships ready for use in a compatible die stock

Compatibility

Designed as a replacement or spare round threading die for use in standard die stock holders sized to accept this die body. Cuts 1/2-16 UNS right-hand external threads on compatible workpiece materials.

Installation Notes

Round threading dies are installed and operated by machinists and maintenance technicians using a die stock holder. Secure the die in the holder using the set screws, aligning the adjustment screw with the die slot before tightening. Apply cutting oil generously to the workpiece before and during threading to extend die life and improve thread finish. Inspect the die edge for chipping before use and do not attempt to thread hardened material beyond the rated capacity of HSS tooling.
