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 with no chips. It is ideal for ductile materials like aluminum, brass, and low-carbon steel in automotive, aerospace, and general machining applications.

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, H5 tolerance for 2B/3B class fit, bottoming chamfer, and is made from cobalt high-speed steel. The manufacturer part number is 1400136900. It is designed for through or blind holes in ductile materials.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide, including this 3/8"-24 UNF cobalt tap. We handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on this and other OSG tooling.

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

Select an OSG thread forming tap based on thread size (e.g., 3/8"-24 UNF), material ductility, hole type (through or blind), and required thread class (2B/3B). Cobalt taps like this one offer heat resistance for harder materials. Consult OSG's application guide for optimal speeds and lubrication.
