Value Collection 315-1098 Round Die 12-40 1 in Od Hss

Product Description

The VALUE COLLECTION 315-1098 is a round threading die used to cut or recut external threads on bolts, studs, and round stock. This die is sized for a 12-40 thread specification with a 1 inch outside diameter, making it compatible with standard 1 inch die stocks and holders. Constructed from high-speed steel (HSS), it maintains cutting edge integrity under friction heat. The adjustable design allows minor diameter correction to achieve a precise thread fit. Machinists, maintenance technicians, and tool-and-die workers use this type of die for both production threading and field repair work.

This die is suited for threading applications in light industrial, maintenance, and repair environments. The 12-40 designation refers to a number 12 screw diameter with 40 threads per inch, a fine-pitch specification common in instrument work, electrical hardware, and precision assemblies. The right-hand thread direction follows standard fastener convention. The 1 inch OD fits widely available round die stocks, making it a practical addition to a threading set used on the bench or in the field.

Key Features

• 12-40 thread size: number 12 diameter, 40 threads per inch fine pitch
• 1 inch outside diameter fits standard round die stocks
• High-speed steel construction for heat and wear resistance during cutting
• Adjustable design allows thread diameter fine-tuning for precise fit
• Right-hand thread direction matches standard fastener convention

Compatibility

Designed as an OEM-style replacement or standard addition for use with 1 inch round die stocks that accept 12-40 threading dies.

Installation Notes

Threading dies are installed and used by machinists and maintenance technicians. Secure the die firmly in a properly sized die stock before use and apply cutting oil to reduce friction and improve thread quality. Inspect the workpiece diameter against the nominal thread specification before cutting to avoid die damage. Replace or recondition dies showing chipped cutting edges to prevent poor thread form.
