Value Collection 314-1140 Round Die 1/4-20 1 in Od Hss

Product Description

The VALUE COLLECTION 314-1140 is a round threading die used to cut external threads on fasteners, bolts, studs, and round stock. Made from high-speed steel (HSS), it is built to handle the heat and friction generated during thread cutting on steel, iron, and similar metals. This die cuts a 1/4-20 UNC right-hand thread and features an adjustable design that allows the technician to fine-tune thread fit and compensate for tool wear. It has a 1 inch outside diameter, fitting standard round die stocks and holders of that size. Machinists, pipefitters, maintenance mechanics, and tool-and-die technicians are the typical end users.

This die is suited for general-purpose threading work in shop, field, and maintenance environments. It produces unified national coarse (UNC) threads, which are the most common fastener thread standard in inch-based applications. Typical uses include cutting threads on replacement studs, repair fasteners, and custom-length bolts where pre-threaded stock is not available. The adjustable feature is particularly useful in production or repair settings where consistent thread engagement across multiple passes is required.

Key Features

• Cuts 1/4-20 UNC right-hand external threads
• High-speed steel construction for heat resistance and extended tool life
• Adjustable design allows thread depth fine-tuning and wear compensation
• 1 inch outside diameter fits standard round die stocks
• Right-hand thread direction matches the vast majority of fastener applications

Compatibility

Designed as an OEM-style replacement or standard tooling choice for use in any round die stock or holder with a 1 inch bore, used in threading 1/4-20 UNC external threads on inch-standard fasteners and round stock.

Installation Notes

Installation is performed by machinists, maintenance mechanics, or trained technicians using a compatible round die stock. Secure the die firmly in the die stock before use, ensuring the set screw engages the adjustment slot. Apply cutting fluid to the workpiece before threading to reduce heat buildup and improve thread quality. Inspect the die for wear or chipping before each use and replace if thread quality degrades.
