Value Collection 315-1156 Round Die 7/16-32 1 in Od Hss

Product Description

The VALUE COLLECTION 315-1156 is a round threading die designed to cut external threads on cylindrical stock. It produces a 7/16-32 UNS right-hand thread profile and features an adjustable split design that allows the cutting diameter to be fine-tuned for fit and finish. Constructed from high-speed steel, the die retains hardness and edge integrity under the heat generated during threading operations. With a 1-inch outside diameter, it fits standard round die stocks used in machine shops, maintenance facilities, and fabrication environments. Machinists and tool-and-die professionals are the primary installers of this type of tooling.

This die is suited for threading operations on small-diameter fastener stock, repair threading of damaged external threads, and prototype or low-volume production work requiring a 7/16-32 UNS thread form. The 7/16-32 designation is a fine-pitch unified national thread, commonly encountered in precision instrument, aerospace, and mechanical assembly applications. The adjustable construction makes it practical for both roughing passes and final sizing, reducing the need for a separate finishing die in many workflows.

Key Features

• 7/16-32 UNS thread size for fine-pitch external threading
• 1-inch outside diameter fits standard round die stocks
• High-speed steel construction for heat resistance and edge retention
• Adjustable split design allows cutting diameter fine-tuning
• Right-hand thread direction matches the majority of standard fastener applications
• UNS thread standard ensures interchangeability with unified national series hardware

Compatibility

Designed for use with standard 1-inch round die stocks and die holders compatible with round threading dies of this outside diameter. Suitable for threading operations on stock materials that accept a 7/16-32 UNS external thread form.

Installation Notes

This tooling is installed and operated by machinists or experienced tradespeople using a compatible round die stock or holder. Secure the die firmly in the holder and verify the set screw engages the die notch before applying cutting pressure. Apply appropriate cutting fluid for the workpiece material to extend die life and improve thread quality. Inspect the die for wear or chipping before each use, as damaged cutting edges produce out-of-tolerance threads.
