Value Collection 314-1040 Round Die 1/4-20 Unc Hss

Product Description

The VALUE COLLECTION 314-1040 is a round threading die designed to cut external threads on rod, bolt stock, and cylindrical workpieces. Made from high-speed steel, this die holds a cutting edge through repeated use and resists heat generated during threading operations. It cuts a 1/4-20 UNC right-hand thread profile and features an adjustable design that allows the operator to fine-tune thread fit by opening or closing the die slightly using a setscrew. This die is a standard tool in any machine shop, maintenance facility, or fabrication environment where threaded fasteners are produced or repaired in-house.

This die is suited for threading mild steel, aluminum, brass, and similar machinable materials in diameters requiring a 1/4-20 UNC profile. Typical applications include fabricating custom-length bolts, restoring damaged threads on existing hardware, and producing threaded rod ends during repair or custom assembly work. The right-hand thread direction matches the standard fastener convention used across general mechanical and industrial applications.

Key Features

• 1/4-20 UNC thread profile for compatibility with standard unified coarse-thread fastener systems
• High-speed steel construction for durability and heat resistance during cutting
• Adjustable design allows fine-tuning of thread fit and cutting depth
• Right-hand thread direction matches standard fastener convention
• Compact round die form fits standard die stocks and holders

Compatibility

Designed for use in standard round die stocks sized to accept dies cut for 1/4-20 UNC external threading applications.

Installation Notes

Threading dies are used by machinists and maintenance technicians working with metal stock or existing hardware. Secure the workpiece firmly in a vise before beginning. Use cutting oil or thread-cutting fluid to lubricate the die and extend tool life. Turn the die stock slowly and reverse periodically to clear chips and prevent binding. The adjustable setscrew should be set before threading begins and only changed between passes, never mid-cut.
