Value Collection 315-1544 Round Die 1-1/4-18 Unef Hss

Product Description

The VALUE COLLECTION 315-1544 is a round threading die used to cut external threads on rod, bolt stock, and fastener blanks. Sized for 1-1/4-18 UNEF (Unified Extra Fine) threads, it is made from high-speed steel (HSS) for durability under repeated use. The adjustable design allows the operator to fine-tune thread fit by expanding or compressing the die body within its holder. Right-hand thread direction is standard for the majority of fastener and repair applications. This die is suited for machine shops, maintenance facilities, and field repair work where threading to a UNEF specification is required.

This die is intended for cutting 1-1/4-18 UNEF external threads on ferrous and non-ferrous materials. It fits standard round die holders sized for the die's outer diameter. Typical applications include threading replacement studs, rods, and damaged fastener shanks in industrial, automotive, and mechanical maintenance settings. The adjustable feature makes it practical for both roughing and finishing passes in a single tool.

Key Features

• Thread size: 1-1/4-18 UNEF (Unified Extra Fine)
• High-speed steel construction for heat resistance and edge retention
• Adjustable die body allows thread fit tuning without changing tools
• Right-hand thread direction for standard fastener applications
• Compatible with standard round die holders for secure, centered cutting

Compatibility

Designed for use in standard round die holders sized to accept this die's outer diameter. Suitable for cutting 1-1/4-18 UNEF external threads on compatible rod or fastener stock.

Installation Notes

Secure the die firmly in a properly sized round die holder before use. Apply cutting fluid appropriate to the workpiece material to reduce heat and extend die life. Start the die square to the workpiece to avoid cross-threading. High-speed steel dies should not be used dry on hardened stock, as this accelerates edge wear and can fracture the die.
