Value Collection 314-1756 Round Die M20x2.5 Hss Metric

Product Description

The VALUE COLLECTION 314-1756 is a round threading die designed to cut external M20x2.5 metric coarse threads on bolts, studs, and round stock. Made from high-speed steel (HSS), it holds an edge under the heat generated during threading operations. The adjustable design allows the cutting diameter to be fine-tuned using a set screw, giving machinists and tradespeople control over thread fit and tolerance. Right-hand thread direction is the standard configuration for the vast majority of metric fastener applications. This die is a hand-tool-shop or lathe-room staple for machinists, maintenance mechanics, and anyone fabricating or restoring threaded fasteners in the field or shop.

This die is suited for threading mild steel, aluminum, brass, and similar machinable materials to the M20x2.5 metric coarse standard. Common applications include fabricating custom fasteners, restoring damaged threads on hydraulic cylinder rods, machine shafts, and structural hardware, and general maintenance threading work in industrial, HVAC, plumbing, and mechanical contracting environments. It fits standard 1-inch round die stocks and holders designed for metric round dies of this size.

Key Features

• M20x2.5 metric coarse thread form for standard metric fastener applications
• High-speed steel construction for heat resistance and extended cutting life
• Adjustable die body allows fine-tuning of thread fit and cutting diameter
• Right-hand thread direction — compatible with standard metric hardware
• Single-piece round die format fits standard round die stocks

Compatibility

Designed as a standard-format round threading die for use in round die stocks and holders sized to accept metric round dies. Cuts M20x2.5 metric coarse external threads per standard metric thread specifications.

Installation Notes

Round dies are installed by a machinist or qualified mechanic using a matching round die stock or die holder. Secure the die in the holder and tighten all set screws before use. Apply cutting oil generously to the workpiece and die during threading to reduce heat buildup and extend tool life. Back off the die periodically to break chips and clear the cutting flutes, especially in deeper threading passes.
