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 manufacturing applications.

What are the specifications of the OSG #2-56 UNC thread forming tap?

This OSG tap is #2-56 UNC, H4 / 2B-3B fit, with a modified bottoming chamfer and TiN coated cobalt construction. The TiN coating reduces friction and extends tool life. It is designed for through or blind holes in ductile materials.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies and delivers OSG thread forming taps worldwide. We handle full logistics and customs clearance, ensuring your order reaches any global destination. Contact us for availability and lead time on this #2-56 UNC TiN coated cobalt tap.

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

Select based on thread size, material, and hole type. For ductile materials like aluminum or brass, a forming tap like this OSG #2-56 UNC works well. Use a modified bottoming chamfer for blind holes. Ensure the H4 / 2B-3B fit matches your tolerance requirements.
