Value Collection 314-1344 Round Die 5/16-18 2in Hss Unc

Product Description

The VALUE COLLECTION 314-1344 is a round threading die designed to cut external threads on bolts, studs, and round stock. It cuts a 5/16-18 Unified National Coarse (UNC) thread profile in a right-hand direction. The die is machined from high-speed steel (HSS), which maintains a sharp cutting edge under the heat and pressure of threading operations. At 2 inches outside diameter, it seats securely in standard 2-inch die stocks and die holders. The adjustable design allows the operator to fine-tune thread fit and compensate for wear, making it a practical choice for production and maintenance threading work.

This die is suited for threading mild steel, aluminum, brass, and similar machinable materials in shop and field environments. Typical applications include fabricating threaded fasteners, repairing damaged threads on existing hardware, and producing custom-length bolts or studs. The 5/16-18 UNC size is one of the most common coarse-thread fastener sizes in general mechanical and structural work, making this die a frequent tool in maintenance, manufacturing, and machine shop settings.

Key Features

• High-speed steel construction maintains cutting edge integrity through repeated use
• 2-inch outside diameter fits standard 2-inch die stocks and holders
• Adjustable design allows fine-tuning of thread tolerance and fit
• Right-hand thread direction matches standard fastener convention

Compatibility

Designed as a standard 2-inch OD round die compatible with any die stock or die holder accepting a 2-inch round die for cutting 5/16-18 UNC external threads.

Installation Notes

Threading dies are installed by machinists and maintenance technicians using a compatible die stock or holder. Ensure the die is seated flat and the set screw is tightened before beginning the cut. Apply cutting oil liberally to the workpiece to reduce heat buildup and extend die life. Back the die off periodically during threading to break chips and prevent binding.
