Value Collection 314-1118 Round Die 5-40 Unc 1 in Od Hss

Product Description

The VALUE COLLECTION 314-1118 is a round threading die designed to cut external threads on bolts, screws, and rod stock. Sized for 5-40 UNC thread form with a 1-inch outside diameter, this die is machined from high-speed steel (HSS) for durability across a wide range of workpiece materials including mild steel, aluminum, and brass. The adjustable design allows the operator to fine-tune thread fit or compensate for die wear, extending service life. Right-hand thread direction is standard for conventional fastener applications. Machinists, tool and die technicians, and maintenance professionals use this die for thread cutting in production and repair environments.

This die is suited for threading small-diameter fasteners and machine screws in both shop and field maintenance settings. The 5-40 UNC designation means 5 thread size with 40 threads per inch, a common specification in light instrumentation, electronics enclosures, and small mechanical assemblies. The 1-inch OD fits standard die stocks and die holders designed for that size, making it straightforward to integrate into existing tooling setups.

Installation Notes

This die is installed in a matching 1-inch round die stock by a machinist or maintenance technician. Secure the die in the holder using the set screws before beginning thread cutting. Apply appropriate cutting fluid to the workpiece before and during threading to reduce heat and improve thread quality. Inspect the die for chips or damage before each use, and adjust the die opening only within the range the adjusting screw allows to avoid cracking the die body.
