Value Collection 314-4380 Round Die 1-14 2 in Od Hss Left Hand

Product Description

The VALUE COLLECTION 314-4380 is a 2-inch outside diameter round die designed to cut 1-14 left-hand external threads on round stock. Manufactured from high-speed steel (HSS), it maintains cutting edge hardness under the heat generated during threading operations. The adjustable design allows the user to fine-tune thread fit by slightly compressing or expanding the die through its adjustment screw. This die follows the UNS (Unified National Special) thread standard and is a standard tool for machinists, pipefitters, and maintenance tradespeople who need to cut or recut external threads on metal fasteners, studs, or rod stock.

This round die is suited for bench or hand die stock use in machine shops, maintenance facilities, and industrial settings where left-hand threaded fasteners or fittings are required. Left-hand thread direction means the die advances clockwise when viewed from the cutting face — the opposite of standard right-hand dies. Applications include cutting replacement threads on left-hand studs, spindle shafts, and specialty hardware where reverse-thread engagement is required to prevent loosening under rotational loads.

Key Features

• High-speed steel construction resists heat buildup during threading cuts
• Adjustable die body allows fine control over thread fit and tolerance
• Left-hand thread direction for reverse-thread applications
• UNS thread standard — 1-14 thread size (1-inch nominal diameter, 14 threads per inch)
• 2-inch outside diameter fits standard round die stocks designed for 2-inch dies

Compatibility

Designed to seat in any standard round die stock or holder with a 2-inch die capacity. Verify that your die stock includes a center adjustment screw to take advantage of the adjustable feature.

Installation Notes

Secure the die in a properly sized die stock before beginning any threading operation. Always apply a suitable cutting oil to the workpiece to extend die life and improve thread finish. Clamp or secure the workpiece in a vise before applying torque to the die stock. Inspect the die for chips or wear before each use — a damaged cutting edge will produce out-of-tolerance threads.
