Value Collection 84030278 Round Die 1/4-27 1 in Od Hss

Product Description

The VALUE COLLECTION 84030278 is a round threading die designed to cut external threads on fasteners, rod stock, and fittings. Sized for a 1/4-27 UNS thread form with a 1 inch outside diameter, this die fits standard 1 inch round die stocks and holders. Machined from high-speed steel, it maintains a cutting edge through repeated use on mild steel, brass, aluminum, and similar materials. The adjustable design allows the operator to fine-tune thread fit by expanding or contracting the die slightly using the adjustment screw in the die stock. Right-hand thread direction is standard for the vast majority of fastener applications. Machinists, pipefitters, maintenance techs, and toolroom personnel are the primary users.

This die suits bench work and field threading tasks where a 1/4-27 UNS thread is required. The UNS (Unified National Special) thread standard at 27 threads per inch is commonly found in instrument fittings, optical equipment mounts, and specialty fastener applications. The 1 inch OD allows use in any die stock or threading handle designed for 1 inch round dies, making it compatible with a wide range of hand-threading and benchtop setups. Suitable for low-volume production, maintenance repair, and custom fabrication work.

Installation Notes

Secure the die firmly in the die stock before beginning threading, ensuring the adjustment screw engages the die adjustment slot. Apply cutting oil to the workpiece and die to extend tool life and improve thread quality. Start the die square to the workpiece to prevent cross-threading. Inspect threads with a thread gauge or mating fastener after cutting to confirm proper fit before final assembly.
