Value Collection 314-1372 Round Die 7/8-9 2 Inch Od Hss

Product Description

The VALUE COLLECTION 314-1372 is a round threading die designed to cut external threads on bolts, studs, and round stock. Manufactured from high-speed steel (HSS), it delivers the hardness and wear resistance needed for threading mild steel, stainless, and similar metals in production or maintenance applications. The die is sized for 7/8-9 thread — meaning a 7/8-inch nominal diameter with 9 threads per inch — and features a 2-inch outside diameter to fit standard round die stocks of that size. The adjustable design allows the operator to fine-tune thread fit by slightly opening or closing the die, making it practical for both roughing and finishing cuts.

This die is suited for machine shops, maintenance facilities, and fabrication environments where field threading or thread restoration is required. It cuts right-hand, Unified National Coarse (UNC) threads, which are the standard thread form across most general-purpose fastener applications in inch-measurement systems. Machinists, millwrights, and industrial maintenance technicians are the primary users. It is appropriate for both new thread cutting on unthreaded rod and for chasing damaged threads on existing fasteners or fittings.

Key Features

• High-speed steel construction provides hardness and heat resistance for extended tool life during threading operations
• Adjustable design allows thread fit tuning between roughing and finishing cuts
• Cuts 7/8-9 UNC right-hand external threads to standard inch fastener specifications
• 2-inch outside diameter fits standard round die stocks designed for 2-inch dies
• Right-hand thread direction matches the vast majority of general-purpose fastener applications

Compatibility

Designed as an OEM-style replacement or standard tooling addition for use in 2-inch round die stocks capable of holding adjustable round dies.

Installation Notes

Round dies are installed and used by machinists and maintenance technicians using a compatible round die stock wrench. Before threading, ensure the workpiece is properly secured in a vise and chamfered at the end to aid die engagement. Apply cutting oil liberally during the threading operation to reduce heat buildup and extend die life. Back off the die periodically to clear chips and prevent binding, especially when threading deeper lengths.
