Value Collection 314-4722 Round Die M12x1.25 Hss Left Hand

Product Description

The VALUE COLLECTION 314-4722 is an adjustable round die designed to cut external M12x1.25 left-hand metric fine threads. Machined from high-speed steel, this die delivers the hardness and heat resistance required for threading steel, stainless, and other ferrous and non-ferrous stock. The adjustable design allows the technician to fine-tune thread fit by opening or closing the die slightly with a set screw. At 1/2 inch thick, it seats correctly in standard round die stocks sized for metric dies. This die is suited for maintenance shops, industrial production, and field repair work where left-hand threaded fasteners are required.

Left-hand thread dies are used wherever reverse-rotation or vibration-resistance requirements dictate a non-standard thread direction, such as on certain machinery shafts, turnbuckles, and specialty fastener applications. This M12x1.25 die covers the fine-pitch variant of the 12 mm metric thread, commonly found in automotive, mechanical, and precision equipment applications. It is installed in a matching round die stock and driven by hand or with a tap-and-die wrench. Machinists, maintenance technicians, and toolroom professionals are the primary users.

Compatibility

Designed for use in standard round die stocks that accept metric round dies. Fits die stocks sized for the 1/2 inch thickness dimension common to this die family.

Installation Notes

Seat the die fully and squarely in a matching round die stock before use and secure all set screws. Apply cutting fluid to the workpiece before threading to extend die life and improve thread finish. Begin threading with light, even pressure, reversing periodically to break chips. Inspect the die for wear or chipping before each use, and never use a cracked or chipped die.
