Value Collection 82235932 Round Die M21x2.5 2 Inch Hss

Product Description

The VALUE COLLECTION 82235932 is a round threading die designed to cut external metric threads on bolts, studs, and rod stock. Sized for M21x2.5 thread profile, this die features a 2-inch outside diameter for use in standard round die stocks. Constructed from high-speed steel (HSS), it holds a cutting edge under the heat and friction generated during threading operations. The adjustable design allows the technician to fine-tune thread fit by opening or closing the die slightly across its split. Right-hand thread direction matches the overwhelming majority of standard fastener applications in mechanical, plumbing, and HVAC work.

This die is suited for threading or re-threading M21x2.5 metric fasteners in maintenance, fabrication, and repair applications. It is appropriate for use in machine shops, field service environments, and trade work where metric thread restoration or new thread cutting is required. The M21x2.5 designation indicates a 21mm nominal diameter with a 2.5mm pitch, classifying it as a metric special thread form. Machinists, pipefitters, and general maintenance technicians commonly use round dies of this type for low-volume threading on a bench-mounted or hand-held die stock.

Key Features

• M21x2.5 metric special thread profile for 21mm nominal diameter rod or fastener stock
• 2-inch outside diameter fits standard round die stock holders of matching size
• High-speed steel construction provides heat resistance and edge retention during cutting
• Adjustable split-die design allows fine tuning of thread fit and cutting depth
• Right-hand thread direction compatible with standard fastener assemblies

Compatibility

Designed as an OEM-style replacement or standard tooling die for use in any round die stock accepting a 2-inch OD die holder. Intended for M21x2.5 metric special thread applications.

Installation Notes

This die is installed and secured in a matching 2-inch round die stock before use. Secure the die firmly with the set screws on the die stock before beginning the thread-cutting pass. Apply cutting oil liberally to the workpiece and die during threading to extend tool life and improve thread quality. Back off the die periodically during cutting to clear chips and reduce binding.
