Value Collection 84047488 Round Threading Die 1-5/8-8 Hss

Product Description

The VALUE COLLECTION 84047488 is a round threading die designed to cut external threads on rod, bolt stock, and cylindrical workpieces. It produces a 1-5/8-8 Unified National Coarse thread profile and features a 3-inch outside diameter for use in standard-size die stocks and holders. Manufactured from high-speed steel (HSS), this die holds cutting edge integrity under the heat and friction generated during threading operations. The adjustable design allows the operator to fine-tune thread fit by slightly opening or closing the die body. Right-hand thread cutting is standard. Machinists, tool-and-die workers, and maintenance mechanics install this type of die for thread repair and production threading tasks.

This die suits shop and field applications where large-diameter external threads must be cut or chased. Typical uses include threading heavy-fastener stock, repair of damaged threads on structural bolts, and production of custom threaded components in maintenance, industrial, and manufacturing environments. The 1-5/8-8 designation indicates a 1-5/8-inch nominal thread diameter with 8 threads per inch, a coarse-pitch specification common in heavy mechanical assemblies and structural fastener applications.

Key Features

• 1-5/8-8 thread size cuts Unified National Coarse external threads at 8 threads per inch
• 3-inch outside diameter fits standard round die stocks designed for that bore size
• High-speed steel construction resists heat buildup and wear during threading cuts
• Adjustable die body allows fine-tuning of thread tolerance and fit
• Right-hand thread direction for standard fastener applications

Compatibility

Designed as an OEM-style replacement or standard production die for use in 3-inch round die stocks and holders that accept dies of this outside diameter.

Installation Notes

This die is installed and operated by machinists or skilled mechanics using a matching round die stock. Secure the die firmly in the stock before beginning a threading pass, and apply cutting fluid throughout the operation to extend die life and improve thread finish. Always work from the correct end of the workpiece and back off the die periodically to clear chips. Follow applicable shop safety practices and use proper personal protective equipment when operating cutting tools.
