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. This #4-48 UNF tap with TiN coated cobalt is ideal for precision applications in automotive, aerospace, and general manufacturing where thread integrity is critical.

What are the specifications of the OSG #4-48 UNF thread forming tap?

This OSG tap is #4-48 UNF with a H3 / 2B-3B fit tolerance, modified bottoming chamfer, and TiN coated cobalt construction. The TiN coating reduces friction and extends tool life. It is designed for general purpose thread forming in materials such as steel, aluminum, and brass.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide, including this #4-48 UNF model. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial solutions provider, we source genuine OSG tooling and support your procurement with technical expertise across 14 industrial departments.

How to select the correct thread forming tap for a job?

Select a thread forming tap based on thread size (e.g., #4-48 UNF), material type, and required thread class (H3 / 2B-3B). Use a modified bottoming chamfer for blind holes. Ensure the tap drill size matches the forming tap's specifications. OSG's TiN coated cobalt taps offer enhanced wear resistance for production runs.
