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. It is commonly used in automotive, aerospace, and general manufacturing for applications requiring high thread strength and no chip evacuation.
What are the specifications of the OSG 9/16"-12 UNC thread forming tap?
This OSG thread forming tap has a 9/16"-12 UNC thread size, H8 / 2B-3B tolerance, modified bottoming chamfer, and is made of cobalt for heat resistance. The manufacturer part number is 1400146700. It is designed for general purpose thread forming in steel and non-ferrous materials.
Where to buy OSG thread forming taps worldwide?

How to select the correct OSG thread forming tap for your application?
Select an OSG thread forming tap based on material type, thread size, and tolerance class. For ductile materials like aluminum or low-carbon steel, use a forming tap with the correct H limit (e.g., H8 for 2B-3B fit). Ensure the chamfer type matches your hole depth—modified bottoming for shallow blind holes.
