Value Collection 314-4264 Round Die 9/16-12 Unc Left Hand Hss

Product Description

The VALUE COLLECTION 314-4264 is a round threading die designed to cut left-hand external threads in a 9/16-12 UNC profile. Manufactured from high-speed steel, it delivers the hardness and wear resistance required for threading steel, iron, and similar ferrous stock. The adjustable design allows the cutting diameter to be fine-tuned for thread fit and to compensate for tool wear, extending service life. This die is a standard hand and machine threading tool used by machinists, pipefitters, and maintenance tradespeople working with left-hand fastener applications.

This die is suited for creating left-hand external threads on bolts, studs, rods, and fittings where reverse-thread fastening is required — common in rotating shaft assemblies, turnbuckles, and applications where vibration would loosen a conventional right-hand thread. The 9/16-12 UNC size is a coarse-thread designation widely used in general mechanical and structural assemblies. It fits standard round die stocks that accept 1-inch OD round dies and is appropriate for both bench-mounted die stock work and low-speed threading machines.

Key Features

• Left-hand UNC thread direction for reverse-thread fastener applications
• High-speed steel construction for durability on ferrous and hard materials
• Adjustable cutting diameter for thread fit control and extended tool life
• 9/16-12 coarse thread pitch suitable for general mechanical and structural use
• Standard round die form fits common 1-inch round die stocks

Compatibility

Designed as a standard round die for use in compatible round die stocks that accept the appropriate OD. Intended for cutting 9/16-12 UNC left-hand external threads on rod, bolt, and stud stock.

Installation Notes

This die is installed and secured in a round die stock before use. Secure the workpiece firmly in a vise before threading. Apply cutting oil generously during the threading operation to reduce heat buildup, improve thread finish, and extend die life. Reverse the die stock periodically to break chips when threading deeper lengths.
