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, burr-free threads in ductile materials like aluminum and steel. It is ideal for high-speed production in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG #12-28 UNF thread forming tap?

This OSG tap is #12-28 UNF size with H3 / 2B-3B tolerance, plug chamfer, and black oxide cobalt finish. The black oxide cobalt coating reduces friction and extends tool life. 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 for international orders. As a global industrial solutions provider, we source genuine OSG tooling and deliver to your facility, ensuring compliance with local import requirements.

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

Select an OSG thread forming tap based on thread size (e.g., #12-28 UNF), material type, and required thread class (H3 / 2B-3B). For ductile materials like aluminum or low-carbon steel, forming taps produce stronger threads. Consult OSG's application data for optimal speeds and lubrication.
