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 and steel. This TiN-coated cobalt H12 tap is ideal for high-production applications requiring precise thread fit and extended tool life.
What are the specifications of the OSG 9/16"-18 UNF thread forming tap?
This OSG tap has a 9/16"-18 UNF thread size, H12 tolerance, modified bottoming chamfer, and TiN-coated cobalt construction. The H12 designation indicates an oversized thread form for controlled fit. It is designed for forming threads in materials up to 850 °C hardness.

How to select the correct OSG thread forming tap size?
Select an OSG thread forming tap by matching the thread size (e.g., 9/16"-18 UNF), tolerance class (H12 for oversized), and chamfer type (modified bottoming) to your application. Ensure the tap is suitable for the workpiece material—TiN coating improves wear resistance in abrasive materials.
