Value Collection 314-4018 Round Die 5-40 Hss Left Hand

Product Description

The VALUE COLLECTION 314-4018 is a round threading die designed to cut external left-hand threads on fasteners and cylindrical stock. Built from high-speed steel (HSS), it delivers the hardness and heat resistance needed for continuous use in shop and field environments. The die cuts to the 5-40 UNC thread standard and features an adjustable design that allows the technician to fine-tune thread fit by slightly opening or closing the die body. It weighs 0.5 pounds and is a practical choice for machinists, maintenance technicians, and trade professionals who work with non-standard or reverse-thread applications.

This die is used wherever a left-hand external thread must be cut on a number 5 screw-size diameter workpiece at 40 threads per inch. Left-hand thread dies are common in applications where standard right-hand threads would loosen under rotational load, such as in certain mechanical assemblies, turnbuckles, and specialty fastener work. The adjustable body allows controlled sizing passes, making it suitable for both roughing and finishing thread cuts on mild steel, aluminum, and similar materials.

Key Features

• High-speed steel construction resists heat buildup during extended threading operations
• Left-hand thread direction for reverse-thread applications where right-hand threads would back out
• Adjustable die body allows thread fit to be dialed in across multiple sizing passes
• 5-40 UNC thread standard for compatibility with number 5 diameter fastener stock
• Compact, round die form fits standard die stocks and holders

Compatibility

Designed as an OEM-style replacement or standard-use round die for use in conventional die stocks and holders sized to accept round dies at the 5-40 thread specification.

Installation Notes

Round dies are installed and used by machinists and maintenance technicians familiar with manual threading operations. Secure the die firmly in a properly sized die stock before beginning any cut. Apply cutting fluid to the workpiece before and during threading to reduce heat and extend die life. Always verify thread direction and thread standard on the workpiece before cutting to avoid mismatched fastener assemblies.
