Osg 2706300 Round Threading Die 1/4-28 Unf Hss

Product Description

The OSG 2706300 is a round threading die designed to cut external 1/4-28 UNF right-hand threads on iron and steel workpieces. Manufactured from high-speed steel, it delivers consistent thread form across a range of threading applications. The die measures 1.5 inches in outside diameter and 0.5 inches thick, fitting standard round die stocks of that size. An adjustable design allows the operator to fine-tune thread fit and compensate for minor wear over the tool's service life. Machinists, pipefitters, and maintenance technicians use this die for thread repair and new thread production in production and field settings.

The OSG 2706300 is suited for threading iron and steel fasteners, studs, and rods to the 1/4-28 UNF standard. The UNF designation indicates a unified fine thread, commonly used where vibration resistance or a finer thread engagement is required compared to coarse-pitch alternatives. This die fits into a 1.5-inch OD round die stock holder, which is a widely available standard size in shop and field toolkits. It is appropriate for both bench work and portable threading operations.

Installation Notes

Install the die securely in a properly sized 1.5 inch round die stock before use, ensuring the set screw engages the adjusting slot on the die face. Apply a suitable cutting fluid to the workpiece before threading to reduce heat buildup and extend die life. Always chamfer or deburr the end of the workpiece before starting the thread to ensure the die engages squarely. Inspect the die for chips or cracks before each use and replace if damaged.
