Value Collection 314-4150 Round Die 3/8-24 1in Od Hss Left Hand

Product Description

The VALUE COLLECTION 314-4150 is a round threading die designed to cut external left-hand threads on fasteners, studs, and rod stock. Made from high-speed steel (HSS), this die handles the heat and friction generated during thread cutting without rapid wear. It produces a 3/8-24 UNF (Unified Fine) thread profile with a 1-inch outside diameter body that fits standard 1-inch round die stocks and holders. The adjustable design allows the operator to fine-tune the cutting depth for a closer fit on initial cuts or cleanup passes. Suitable for manual and machine-assisted threading operations in maintenance, fabrication, and repair environments.

This die is used wherever left-hand external threads are required — reverse-thread applications in mechanical assemblies, specialty fastener fabrication, or repair of existing left-hand threaded components. The 3/8-24 UNF specification makes it a fit for fine-pitch threading work on smaller-diameter rod and bolt stock. Metalworking shops, maintenance technicians, and precision fabricators will encounter this die in bench threading setups using a standard 1-inch die stock handle.

Key Features

• High-speed steel construction resists heat buildup during sustained thread cutting
• Left-hand thread direction for reverse-thread fastener and assembly applications
• Adjustable design allows cutting depth fine-tuning for initial cuts and thread chasing
• 3/8-24 UNF thread standard ensures consistent fine-pitch thread geometry
• 1-inch OD fits standard round die stocks and holders

Compatibility

Designed for use with standard 1-inch round die stocks and holders compatible with 1-inch OD round dies. Cuts 3/8-24 UNF left-hand external threads on steel, aluminum, and similar machinable materials.

Installation Notes

Secure the die firmly in a properly sized 1-inch round die stock before use. Apply cutting fluid generously to the workpiece and die to reduce heat and extend tool life. Advance the die in short increments and back off periodically to clear chips and prevent thread damage. Always verify the required thread direction — left-hand — before beginning the cut, as reversing a threading operation after the fact can damage the workpiece.
