Value Collection 315-1670 Round Threading Die 2-4-1/2 Unc

Product Description

The VALUE COLLECTION 315-1670 is a round threading die designed to cut external threads on rod, bolt blanks, and round stock. It produces a 2-4-1/2 UNC thread profile and features an adjustable design that allows the cutting diameter to be fine-tuned for thread fit. The die is manufactured from high-speed steel, giving it the hardness and heat resistance needed for sustained cutting performance. At 3 inches in outside diameter, it is sized to fit standard die stocks and holders compatible with that OD. This die is suited for machinists, maintenance technicians, pipefitters, and fabricators who cut threads manually or with a die stock in a production or repair environment.

This die is appropriate for threading mild steel, stainless, aluminum, and similar machinable materials where a 2-4-1/2 UNC external thread is required. Typical applications include creating or restoring threads on fasteners, studs, and threaded rod in industrial, maintenance, and fabrication settings. The right-hand thread direction matches the standard orientation used in the vast majority of threaded fastener applications.

Key Features

• Cuts 2-4-1/2 UNC external threads per Unified National Coarse standard
• 3-inch outside diameter fits compatible die stocks and holders
• High-speed steel construction for durability and heat resistance during cutting
• Adjustable design allows fine-tuning of thread cutting diameter for proper fit
• Right-hand thread direction for standard fastener applications

Compatibility

Designed for use in standard round die stocks and holders with a 3-inch bore. Fits threading applications requiring a 2-4-1/2 UNC external thread profile.

Installation Notes

This die is installed and secured in a compatible 3-inch die stock before use. Ensure the die is seated squarely against the workpiece at the start of the cut to prevent cross-threading. Apply cutting fluid appropriate to the workpiece material to extend die life and improve thread quality. Adjustment screws on the die should be set and locked before beginning the threading pass.
