Product Description

OSG General Purpose Thread-Forming Taps.

Frequently Asked Questions

What is an OSG thread forming tap used for?

An OSG thread forming tap creates internal threads by displacing material rather than cutting it, producing stronger threads in ductile materials like aluminum, brass, and steel. It is ideal for applications requiring high thread strength and no chip generation.

What are the specifications of the OSG 3/8"-24 UNF thread forming tap?

This OSG tap has a 3/8"-24 UNF thread size, H4 / 2B-3B tolerance, plug chamfer, and TiN coated cobalt construction. The manufacturer part number is 1400138205. It is designed for general purpose thread forming in a range of materials.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide, handling full logistics and customs clearance. As a global industrial solutions provider, we source and deliver genuine OSG cutting tools to your location. Contact us for availability and lead time.

How to select the right OSG thread forming tap for your application?

Select an OSG thread forming tap based on thread size (e.g., 3/8"-24 UNF), material type, and required thread class (e.g., H4 / 2B-3B). For ductile materials, forming taps produce stronger threads. Consult OSG's technical data for optimal speed and lubrication.
