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 like aluminum and steel. It is ideal for applications requiring high thread strength and chip-free operation.
What are the specifications of the OSG #3-56 UNF thread forming tap?
This OSG tap has a #3-56 UNF thread size, H5 tolerance for 2B class fit, and a modified bottoming chamfer for threading close to blind-hole bottoms. It is made from cobalt for heat resistance and durability, with MPN 1400104600.

How to select the right OSG thread forming tap for your application?
Select an OSG thread forming tap based on material type, thread size, and hole depth. For ductile materials like aluminum, use a forming tap with proper chamfer (e.g., modified bottoming for blind holes). Ensure tolerance matches your thread class, and choose cobalt for high-speed or tough materials.
