Value Collection 314-1046 Round Die 5/16-24 Unf Hss

Product Description

The VALUE COLLECTION 314-1046 is a round threading die designed to cut external threads on rod, bolt stock, and fastener blanks. Built from high-speed steel (HSS), it holds a cutting edge through repeated use on ferrous and non-ferrous metals. The die is adjustable, allowing the technician to dial in thread fit by opening or closing the die body slightly with a set screw. It cuts a 5/16-24 UNF right-hand thread — a fine-thread profile used widely in mechanical assemblies where vibration resistance and precise clamping force matter. Machinists, maintenance mechanics, and trade professionals working with threaded fasteners are the primary users.

This die suits repair and fabrication work across industrial maintenance, HVAC equipment assembly, plumbing fixture work, and general mechanical service. The 5/16-24 UNF thread specification fits applications requiring fine-pitch external threads on 5/16-inch diameter stock. It is used with a standard round die stock holder sized for the die's outer diameter. The adjustable design makes it practical for both chasing damaged threads and cutting new ones to fit varying tolerance requirements.

Key Features

• High-speed steel construction retains cutting edge hardness under heat generated during threading
• Adjustable body allows thread fit tuning without changing tooling
• Right-hand thread direction matches standard fastener orientation
• 5/16-24 UNF thread form suited to fine-pitch fastener applications
• Round die form fits standard round die stock holders

Compatibility

Designed for use with standard round die stock holders that accept the appropriate outer diameter. Cuts 5/16-24 UNF external threads on compatible diameter stock.

Installation Notes

Round dies are installed and used by machinists and maintenance mechanics using a matching die stock holder. Apply cutting oil to the workpiece before threading to reduce heat buildup and extend die life. Ensure the die is seated squarely against the stock before applying rotational force to avoid cross-threading. Inspect the die for wear or chipping before each use, particularly when working with hardened materials.
