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 in ductile materials like aluminum, steel, and brass. It is ideal for high-speed production 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, H8 / 2B-3B tolerance, plug chamfer, and TiN coating on cobalt steel. The TiN coating reduces friction and extends tool life. Manufacturer part number is 1400136305.

How to select the right thread forming tap for your application?
Select a 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 TiN coating for longer life. Match the tap's H limit (e.g., H8) to your required thread class (2B or 3B).
