Osg 2703700 Round Threading Die 7/16-14 1 Inch Od Hss

Product Description

The OSG 2703700 is a round threading die designed to cut external 7/16-14 UNC threads on iron and steel workpieces. Made from high-speed steel (HSS), this die delivers consistent thread form under the heat and friction of production and job-site threading applications. The 1-inch outside diameter fits standard die stock handles sized for 1-inch round dies. At 3/8 inch thick and 0.15 pounds, it is compact enough for handheld use while maintaining rigidity for accurate thread cutting. The adjustable design allows the operator to fine-tune thread fit tolerance without replacing the die. Right-hand thread direction is the standard orientation for UNC fastener applications.

This die is suited for threading bolts, studs, alloy rod, and fastener stock in iron and steel. It fits naturally into maintenance, fabrication, pipe fitting, and mechanical service workflows where UNC 7/16-14 threads are required. Typical users include machinists, pipefitters, millwrights, and maintenance technicians working in commercial and industrial settings. The 7/16-14 UNC designation is a coarse-thread standard common in structural fastening, equipment repair, and general mechanical assembly.

Key Features

• High-speed steel construction resists heat buildup during threading operations on iron and steel
• Adjustable die body allows fine-tuning of thread fit tolerance
• 1-inch outside diameter fits standard round die stocks sized for 1-inch dies
• Right-hand, 7/16-14 UNC thread form matches the most common coarse-thread fastener standard
• 3/8-inch thickness provides adequate die depth for clean, full-form threads
• Lightweight at 0.15 pounds for easy handling in handheld die stock use

Compatibility

Designed for use on iron and steel workpieces requiring 7/16-14 UNC external threads. Fits standard round die stocks with a 1-inch die cavity.

Installation Notes

Threading dies should be installed by a qualified machinist or mechanical tradesperson familiar with hand threading tools. Secure the die firmly in the die stock before use and apply appropriate cutting oil to the workpiece to extend die life and improve thread quality. Inspect the workpiece diameter against the nominal 7/16-inch major diameter specification before threading to avoid die damage. Never force a die over an oversized blank, as this can chip the cutting edges or distort the thread form.
