Value Collection 314-4154 Round Die 7/16-20 1in Od Hss Left Hand

Product Description

The VALUE COLLECTION 314-4154 is a round threading die designed to cut external left-hand threads on metal stock. Sized at 7/16-20 UNF with a 1-inch outside diameter, it fits standard 1-inch die stocks and threading handles used in machine shops and field maintenance work. The die is manufactured from high-speed steel (HSS), which retains cutting hardness under the heat generated during threading operations. An adjustable design allows the operator to fine-tune thread depth and fit for precise results. This die is suited for machinists, tool-and-die workers, and maintenance mechanics who need to produce left-hand threaded fastener connections.

This die is used wherever left-hand external threads must be cut on bolt blanks, rod stock, or repair fasteners in 7/16-20 UNF specification. Left-hand thread dies are commonly required in applications where counter-rotation forces would otherwise loosen a standard right-hand fastener, such as certain spindle assemblies, bicycle components, and specialty mechanical equipment. The 1-inch OD makes it compatible with widely available round die stocks found in most threading sets.

Key Features

• 7/16-20 UNF thread specification for precise fine-thread cutting
• Left-hand thread direction for counter-rotation fastener applications
• High-speed steel construction maintains cutting edge under heat and load
• Adjustable die allows thread depth and fit tuning
• 1-inch outside diameter fits standard round die stocks

Compatibility

Designed for use with standard 1-inch round die stocks and threading handles. Intended for cutting 7/16-20 UNF left-hand external threads on compatible metal workpieces.

Installation Notes

Secure the die firmly in a properly sized die stock before beginning any threading operation. Apply appropriate cutting oil to the workpiece to reduce heat and extend die life. Start the die squarely on the stock to avoid cross-threading. Follow shop safety practices and wear eye protection when operating threading tools.
