Value Collection 315-1323 Round Die 7/8-20 2 Inch Od Hss

Product Description

The VALUE COLLECTION 315-1323 is a round threading die designed to cut external threads on rod, bolt stock, and cylindrical workpieces. Sized for a 7/8-20 thread form with a 2-inch outside diameter, this die is manufactured from high-speed steel for durability under the heat and friction generated during thread cutting. The adjustable design allows the operator to fine-tune thread fit and take multiple passes for a cleaner thread profile. It cuts right-hand threads conforming to the UNEF (Unified Extra Fine) thread standard. Machinists, tool and die makers, and maintenance technicians install this type of die using a standard round die stock or die holder.

This die is suited for applications requiring extra-fine thread pitch, which is common in precision mechanical assemblies, instrumentation, and aerospace or automotive repair work where fine thread engagement is critical. The 7/8-20 UNEF specification makes it appropriate for stock that demands a tighter thread pitch than standard UNF or UNC fasteners. It is used in both shop and field environments wherever external threads need to be cut or restored on a 7/8-inch diameter workpiece.

Key Features

• 7/8-20 thread size with UNEF (Unified Extra Fine) thread standard
• 2-inch outside diameter fits standard round die stocks for that size
• High-speed steel construction resists heat buildup during thread cutting
• Adjustable design allows thread fit tuning and multi-pass cutting
• Right-hand thread direction for conventional fastener applications
• Single-piece packaging suitable for individual replacement or toolbox stocking

Compatibility

Designed for use in any standard 2-inch round die stock or die holder that accepts a 2-inch OD round die. Intended for cutting 7/8-20 UNEF right-hand external threads on compatible workpiece diameters.

Installation Notes

This die is installed by a machinist or skilled tradesperson into a matching round die stock; ensure the die stock set screw engages the adjustment slot on the die before use. Secure the workpiece firmly in a vise and apply cutting oil generously to reduce heat and improve thread finish. Back the die off periodically to clear chips and prevent binding. Inspect threads with a calibrated thread gauge after cutting to confirm fit and pitch before final assembly.
