Product Description

OSG Spiral-Point Extension Taps for Steel & Stainless Steel.

Frequently Asked Questions

What is an OSG extension tap used for?

An OSG extension tap is used to thread deep or hard-to-reach holes in steel and stainless steel. Its extended reach and spiral-point design push chips forward, making it ideal for through-hole applications in automotive, aerospace, and general machining where standard taps cannot access the workpiece.

What are the specifications of the OSG extension tap 1764201?

The OSG extension tap 1764201 is a #6-32 UNC spiral-point tap with a plug chamfer and 2 flutes. It has an H3 / 2B-3B thread tolerance, designed for threading steel and stainless steel. The extension length allows access to recessed areas, and the spiral-point geometry pushes chips ahead for clean through-hole threads.

Where to buy OSG extension taps worldwide?

3G Electric supplies OSG extension taps worldwide, handling full logistics and customs clearance for global delivery. As a sourcing partner, we provide genuine OSG taps like the 1764201 to industrial buyers across 14 departments, including machining and tooling. Contact us for availability and lead time to your location.

How to select the right OSG extension tap for steel?

To select the right OSG extension tap for steel, match the thread size (e.g., #6-32 UNC), chamfer type (plug for through-holes), and flute count (2-flute spiral-point for chip evacuation). Confirm the thread tolerance (H3 / 2B-3B) fits your application. For deep or obstructed holes, choose an extension length that provides clearance without compromising rigidity.
