Value Collection 315-1200 Round Die 1/4-32 Hss Unef

Product Description

The VALUE COLLECTION 315-1200 is a round threading die designed to cut external threads on fasteners, rod stock, and fittings. Sized for 1/4-32 UNEF (Unified Extra Fine) threads and machined from high-speed steel (HSS), this die handles right-hand thread cutting in production and repair applications alike. The adjustable construction lets the user dial in thread fit by slightly opening or closing the die body with a set screw, giving machinists and tradespeople control over thread tolerance. It is a standard round die compatible with common die stocks and holders of the appropriate size.

This die is suited for threading small-diameter work where extra-fine pitch is required, such as instrument components, hydraulic fittings, and precision fastener repair. The 1/4-32 UNEF designation is common in applications that demand greater thread engagement and vibration resistance compared to coarser thread series. It is used by machinists, pipefitters, and maintenance technicians in shop and field settings.

Key Features

• 1/4-32 UNEF thread size for extra-fine pitch external threading
• High-speed steel construction for durability across a range of materials
• Right-hand thread direction, the standard for most fastener and fitting work
• Adjustable die body allows thread fit fine-tuning via set screw
• Round die form fits standard die stocks and holders

Compatibility

Designed as an OEM-style replacement or standard-use round die for use with die stocks and holders sized to accept a round die in the appropriate outside diameter. Verify die stock compatibility before use.

Installation Notes

Round dies are installed and driven by a matching die stock or holder — confirm the die outside diameter matches your die stock before use. Secure the die fully in the stock before cutting threads. Apply cutting oil to both the die and the workpiece to extend die life and improve thread quality. Inspect the die for cracks or chipped teeth before each use and replace if damaged.
