Value Collection 314-1626 Round Die M4x0.5 1 Inch Od Hss

Product Description

The VALUE COLLECTION 314-1626 is a round threading die designed to cut external M4x0.5 metric fine threads on fasteners, studs, and cylindrical stock. Machined from high-speed steel (HSS), this die holds an edge under the heat and friction of threading operations. The 1-inch outside diameter fits standard round die stocks and holders. The adjustable design allows the operator to fine-tune thread fit and cutting pressure, reducing the chance of oversized or undersized threads on the finished workpiece. It is used by machinists, maintenance technicians, and trade professionals who need to chase damaged threads or cut new metric threads in the field or shop.

This die is suited for production and maintenance applications where M4x0.5 metric fine external threads are required. Typical use cases include threading small-diameter fastener stock, repairing stripped bolt threads on HVAC equipment components, electrical enclosure hardware, and plumbing fittings. The right-hand thread direction is standard for the vast majority of metric fastener applications. The 1-inch OD is a common size that accepts a wide range of commercially available round die holders.

Key Features

• M4x0.5 metric fine thread specification for precise, close-tolerance threading
• High-speed steel construction for durability under heat and repeated use
• Adjustable design allows thread fit fine-tuning during cutting
• 1-inch outside diameter fits standard round die stocks
• Right-hand thread direction — compatible with standard metric fastener assemblies
• Metric fine thread standard for applications requiring tighter thread pitch than coarse series

Compatibility

Designed for use in standard 1-inch round die holders and die stocks commonly used for metric threading operations.

Installation Notes

This die is installed into a matching round die holder or die stock before use. Secure the die firmly in the holder using the set screws before beginning any threading operation. Apply cutting fluid to the workpiece and die to reduce heat buildup and extend die life. Inspect the die for chipping or wear before each use, as a damaged cutting edge will produce poor thread quality.
