Value Collection 315-1125 Round Die 1/4-40 1 Inch Od Hss

Product Description

The VALUE COLLECTION 315-1125 is a round threading die designed to cut external threads on rod, bolt stock, and fastener blanks. It cuts a 1/4-40 UNS thread profile with a right-hand thread direction. The die body measures 1 inch in outside diameter and is machined from high-speed steel for durability and heat resistance during cutting operations. An adjustable design allows the operator to fine-tune thread fit by slightly opening or closing the die body using a set screw. Machinists, toolmakers, and maintenance technicians use this type of die for both production threading and repair work on existing threaded components.

This die is suited for threading operations on small-diameter stock requiring a 1/4-40 UNS thread form. The 1/4-40 designation indicates a 0.25-inch nominal diameter with 40 threads per inch, a fine-pitch specification common in instrument work, optical equipment, precision assemblies, and small mechanical fasteners. The 1-inch OD fits standard round die stocks and holders designed for that body diameter, making it compatible with common bench-top and hand-held die stock tools used in machine shops and maintenance environments.

Key Features

• 1/4-40 UNS thread form with 40 threads per inch for fine-pitch applications
• High-speed steel construction provides wear resistance and handles heat buildup during threading
• Adjustable die body allows fine-tuning of thread fit and tolerance
• Right-hand thread direction for standard fastener compatibility
• 1-inch outside diameter fits common round die stocks and holders

Compatibility

Designed as a replacement or supplementary round die for use in standard 1-inch OD round die stocks and holders used in manual and bench-top threading operations.

Installation Notes

This die is installed and used by machinists and maintenance technicians following standard threading procedures. Secure the die firmly in a properly sized die stock before use and apply an appropriate cutting fluid to the workpiece to reduce friction and improve thread quality. Inspect the workpiece diameter against the specified nominal size before threading to avoid die damage or poor thread form. Adjust die opening with the set screw before cutting to achieve the desired thread fit class.
