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, steel, and stainless steel in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG 3/8"-16 UNC thread forming tap?

This OSG tap has a 3/8"-16 UNC thread size, H7 / 2B-3B tolerance, bottoming chamfer, and TiN coated cobalt construction. The manufacturer part number is 1400134705. It is designed for general purpose thread forming in a range of materials.

Where to buy OSG thread forming taps worldwide?

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

Select a thread forming tap based on material type, thread size, and tolerance class. For ductile materials, use a forming tap like this OSG TiN coated cobalt version. Match the chamfer type to hole depth: bottoming for blind holes, plug for through holes. Always use proper lubrication.
