Value Collection 314-4376 Round Die 7/8-14 2in Od Lh Hss

Product Description

The VALUE COLLECTION 314-4376 is a round threading die designed to cut left-hand external threads in a 7/8-14 UNF thread form. Made from high-speed steel (HSS), this die maintains cutting edge integrity across a wide range of workpiece materials including mild steel, aluminum, and brass. The 2-inch outside diameter fits standard round die stocks and holders designed for that OD. The adjustable design allows the operator to fine-tune thread fit by opening or closing the die body slightly via the set screw provisions in the die stock. This die is intended for use by machinists, toolmakers, and maintenance professionals who need to produce or restore left-hand threaded fastener profiles on rod or bolt stock.

This die is suited for threading applications where left-hand thread direction is required, such as certain mechanical assemblies, turnbuckles, and safety-critical connections that use reverse-thread fasteners to prevent loosening under rotation. It is used in machine shops, manufacturing facilities, and maintenance environments. Compatible with standard 2-inch round die stocks. The 7/8-14 UNF specification targets fine-pitch threading on 7/8-inch diameter stock.

Key Features

• Left-hand thread direction for reverse-thread applications
• 7/8-14 UNF thread form — fine pitch for 7/8-inch diameter stock
• High-speed steel construction for durability and heat resistance during cutting
• Adjustable body allows thread fit fine-tuning via die stock set screws
• 2-inch OD fits standard round die stocks and holders

Compatibility

Designed to fit standard round die stocks and holders with a 2-inch die opening. Verify that your die stock accommodates a 2-inch OD round die before use.

Installation Notes

This die is installed and operated by machinists or maintenance technicians using a compatible 2-inch round die stock. Secure the die firmly in the stock using the set screws before beginning thread cutting. Apply appropriate cutting oil to the workpiece to reduce friction and extend die life. Never force the die through oversized stock — ensure the rod diameter is within the specified blank diameter tolerance for a 7/8-14 UNF thread before starting.
