Value Collection 314-1242 Round Die 1/4-28 Unf Hss

Product Description

The VALUE COLLECTION 314-1242 is a round threading die designed to cut external threads on bolts, studs, and round stock. Made from high-speed steel, this die holds its cutting edge under the heat and stress of threading operations on a wide range of metals. It is sized for 1/4-28 UNF thread, meaning it cuts a quarter-inch diameter with 28 threads per inch in the Unified Fine thread standard. The adjustable design allows a machinist or technician to tune the die for a tighter or looser thread fit. Thread direction is right hand, which is the standard for the vast majority of fastener applications.

This die is used in machine shops, maintenance facilities, and field service situations wherever external threads need to be cut or restored. Common applications include threading new rod stock, cleaning up damaged bolt threads, and fabricating custom fasteners. Electricians, pipefitters, and general maintenance technicians reach for dies like this when field repairs require a fresh thread on a shaft or stud. The 1/4-28 UNF size is common in precision assemblies, instrument work, and light mechanical equipment.

Key Features

• 1/4-28 UNF thread size for fine-pitch external threading
• High-speed steel construction for durability and heat resistance during cutting
• Adjustable design allows thread fit to be tuned without changing dies
• Right-hand thread direction, compatible with standard fastener orientation
• Round die form fits standard round die stocks and holders

Compatibility

Designed as a standard round die for use with round die stocks and holders sized to accept the die body. Cuts 1/4-28 UNF external threads on steel, aluminum, brass, and similar machinable materials.

Installation Notes

Round dies are installed by machinists or maintenance technicians using a matching die stock or holder. Secure the die firmly in the holder before beginning any threading pass. Apply a suitable cutting oil to the workpiece before and during threading to extend die life and improve thread finish. Always back off the die periodically to clear chips and prevent binding or breakage.
