Value Collection 315-1333 Round Die 15/16-20 Unef 2 in Hss

Product Description

The VALUE COLLECTION 315-1333 is a round threading die sized 15/16-20 UNEF, designed to cut external threads on round stock in a single controlled pass. Made from high-speed steel (HSS), the die maintains cutting edge hardness under the heat and friction generated during threading operations. The 2-inch outside diameter fits standard round die stocks and holders used in machine shops and field service. The adjustable design allows cutting pressure to be tuned for thread quality and tool life. Right-hand thread direction is standard for general fastener and fitting applications.

This die is suited for machinists, toolmakers, pipefitters, and maintenance technicians who need to cut or recut 15/16-20 UNEF threads on bolt blanks, studs, shafts, or threaded rod. The UNEF (Unified National Extra Fine) thread form is common in precision assemblies, instrumentation, and aerospace-adjacent applications where fine thread pitch provides greater tensile strength and finer adjustment than UNC or UNF threads. The 2-inch OD and adjustable construction make it compatible with most standard die stocks available in trade and industrial settings.

Key Features

• 15/16-20 UNEF thread size for extra fine pitch external threading
• High-speed steel construction retains hardness at elevated cutting temperatures
• 2-inch outside diameter fits standard round die stocks and holders
• Adjustable design allows fine-tuning of thread fit and cutting pressure
• Right-hand thread direction for standard fastener and fitting applications

Compatibility

Designed as an OEM-style replacement or direct-use round die fitting standard 2-inch round die stocks and holders used for cutting UNEF external threads.

Installation Notes

Round dies are installed and used by machinists and maintenance technicians following standard threading procedure. Secure the die firmly in a properly sized die stock before use, and apply cutting fluid appropriate for the workpiece material to extend tool life and improve thread finish. Inspect the workpiece diameter against published UNEF tolerance charts before threading to avoid die damage or poor thread fit. Do not force the die if resistance increases sharply — back off to clear chips and reapply cutting fluid.
