Value Collection 314-1503 Round Threading Die 1-1/8

Product Description

The VALUE COLLECTION 314-1503 is a round threading die designed to cut external UNC threads on rod, bolt stock, and fastener blanks. It measures 3 inches in outside diameter and cuts a 1-1/8-7 thread size, which is a coarse-pitch Unified National Coarse profile. The die is machined from high-speed steel for durability under repeated use and elevated cutting temperatures. An adjustable split design allows the operator to fine-tune thread fit by opening or closing the die within a standard die stock holder. Right-hand thread direction follows the conventional fastener standard. Machinists, tool-and-die makers, and maintenance tradespeople use this die for production threading and repair work.

This die is suited for threading operations on ferrous and non-ferrous workpieces in shop, maintenance, and light manufacturing environments. The 3-inch OD fits standard round die stocks and holders sized for that diameter. The 1-1/8-7 UNC thread form is common in heavy-duty fastener applications including structural assemblies, machinery frames, and industrial equipment. The adjustable design is particularly useful when cutting threads on harder materials where a single-pass cut at full depth may not be practical.

Key Features

• 1-1/8-7 UNC thread size for coarse-pitch external threading
• 3-inch outside diameter fits standard round die stocks
• High-speed steel construction resists heat and wear during cutting
• Adjustable split design allows thread tolerance fine-tuning
• Right-hand thread direction matches standard fastener convention
• Unified National Coarse (UNC) thread standard

Compatibility

Designed for use in standard round die stocks and holders that accept a 3-inch OD die. Suitable for cutting 1-1/8-7 UNC external threads on rod or bar stock in bench, lathe, or hand-held die stock applications.

Installation Notes

This die is installed and operated by machinists or maintenance tradespeople familiar with threading tooling. Secure the die firmly in a properly sized die stock before use, and ensure the workpiece is clamped or chucked to prevent movement during threading. Apply cutting fluid appropriate to the workpiece material to extend die life and improve thread finish. Inspect the die for chips or damage before each use and adjust the split for proper thread fit before committing to a final pass.
