Value Collection 315-1671 Round Threading Die 2-8 3 in Od Hss

Product Description

The VALUE COLLECTION 315-1671 is a round threading die designed to cut external 2-8 unified national coarse (UNC) threads on round stock. The die measures 3 inches in outside diameter and is machined from high-speed steel (HSS), which maintains cutting-edge hardness at elevated temperatures generated during threading operations. An adjustable split design allows the technician to fine-tune thread fit and compensate for tool wear. Right-hand thread orientation matches the standard fastener convention used across the majority of industrial and mechanical applications. Machinists, pipefitters, and maintenance technicians use this die for threading rod, bolt blanks, and threaded shaft stock.

This die is suited for threading 2-inch diameter round stock at 8 threads per inch in shop, maintenance, and field fabrication environments. The 3-inch OD is a standard size that seats in compatible die stocks and die holders designed for that shell diameter. Applications include heavy fabrication, structural repair, and custom shaft threading where a 2-8 UNC thread form is specified. The HSS construction makes it appropriate for threading mild steel, alloy steel, and similar ferrous materials at moderate cutting speeds.

Key Features

• 2-8 UNC thread size cuts external threads on 2-inch diameter stock at 8 TPI
• 3-inch outside diameter fits standard die stocks accepting that shell size
• High-speed steel construction resists heat buildup during threading operations
• Adjustable split design allows thread fit adjustment and accommodates tool wear
• Right-hand thread direction matches standard fastener convention

Compatibility

Designed as an OEM-style replacement or direct-use round threading die for die stocks and die holders accepting a 3-inch outside diameter shell.

Installation Notes

Threading dies are installed by machinists and maintenance technicians using a compatible die stock sized for the 3-inch OD. Secure the die firmly in the stock before beginning the threading operation and apply cutting oil continuously to reduce heat and extend tool life. Start the die square to the workpiece to prevent cross-threading. Follow shop safety procedures including securing the workpiece in a vise or fixture before applying torque to the die stock.
