Value Collection 84048189 Round Die 1-7/8 16 3in Hss

Product Description

The VALUE COLLECTION 84048189 is a round threading die designed to cut external threads on cylindrical stock. It produces a 1-7/8-16 thread profile to the UNS (Unified National Special) standard and features right-hand thread direction. The die is manufactured from high-speed steel (HSS), which maintains cutting edge hardness under the heat generated during threading operations. An adjustable design allows the operator to dial in thread fit by compressing or expanding the die slightly within its holder. The 3-inch outside diameter is a standard size compatible with most round die stocks and holders of that bore. Machinists, pipefitters, and maintenance technicians working with large-diameter threaded fasteners or fittings are the primary users.

This die is suited for threading large-diameter rod, bolt blanks, or shaft stock where a 1-7/8-16 UNS thread form is required. Applications include industrial maintenance, toolroom work, and fabrication environments where non-standard or specialty thread sizes appear on equipment, fixtures, or heavy assemblies. The right-hand thread direction covers the vast majority of standard fastening applications. Because this is a UNS thread, it is commonly encountered on specialized mechanical assemblies rather than in typical plumbing or HVAC pipework.

Key Features

• 1-7/8-16 thread size in UNS standard for specialty large-diameter threading applications
• High-speed steel construction retains hardness and cutting edge at elevated temperatures
• Adjustable design allows fine-tuning of thread fit and cutting tension
• 3-inch outside diameter fits standard round die stocks and holders of that bore size
• Right-hand thread direction for conventional fastening assemblies

Compatibility

Designed for use in standard 3-inch round die stocks and holders. Suitable for cutting external 1-7/8-16 UNS right-hand threads on steel, aluminum, brass, and similar machinable materials.

Installation Notes

This die is installed and operated by machinists or qualified maintenance technicians using a properly sized round die stock. Secure the die firmly in the die stock using the set screws before beginning any threading operation. Apply cutting oil generously to the workpiece and die throughout the threading process to extend tool life and improve thread finish. Inspect the workpiece for proper diameter before threading to ensure the die cuts within its designed range.
