Value Collection 315-1210 Round Die 5/16-32 Hss Unef

Product Description

The VALUE COLLECTION 315-1210 is a round threading die designed to cut external threads on fasteners, bolts, rods, and threaded components. Made from high-speed steel, it delivers the hardness and heat resistance needed for consistent thread cutting in a shop or field environment. The die is sized for a 5/16-32 thread profile conforming to the UNEF (Unified Extra Fine) standard and features right-hand thread cutting geometry. An adjustable design allows minor diameter corrections to compensate for wear or to fine-tune thread fit. Machinists, pipefitters, and maintenance technicians use this type of die for fabrication, repair, and rethreading applications.

This die is suited for cutting 5/16-32 UNEF right-hand external threads on steel, aluminum, and similar machinable materials. It is appropriate for both production and repair threading tasks where extra-fine thread pitch is required. The UNEF thread standard is common in precision mechanical assemblies, aerospace-adjacent hardware, and applications where fine pitch provides greater clamping force or vibration resistance. The die is used in a standard round die stock holder sized for the die's outside diameter.

Key Features

• 5/16-32 UNEF thread size for extra-fine pitch threading applications
• High-speed steel construction for hardness and thermal resistance during cutting
• Adjustable design allows thread diameter fine-tuning and compensation for wear
• Right-hand thread cutting geometry for standard fastener thread direction
• Designed for use in a standard round die stock holder

Compatibility

Designed as a standard round threading die for use with round die stock holders accepting the appropriate outside diameter. Compatible with applications requiring 5/16-32 UNEF right-hand external threads.

Installation Notes

Secure the die firmly in a properly sized round die stock holder before use. Apply cutting oil generously to the workpiece and die to reduce heat buildup and extend cutting life. Back off the die periodically during threading to break chips and prevent binding. Always inspect the workpiece for proper diameter and surface condition before threading to avoid die damage.
