Frequently Asked Questions

What is an OSG thread forming tap used for?

An OSG thread forming tap creates internal threads in ductile materials like aluminum, brass, and steel without cutting. It displaces material to form threads, producing stronger, burr-free threads ideal for aerospace, automotive, and general manufacturing applications.

What are the specifications of the OSG #2-56 UNC thread forming tap?

This OSG tap is #2-56 UNC size with a H4 / 2B-3B tolerance, bottoming chamfer, and made from cobalt for durability. The manufacturer part number is 1400102400. It forms threads in blind or through holes for precision fastening.

Where to buy OSG thread forming taps worldwide?

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

Select an OSG thread forming tap based on material type, thread size, and hole condition. For #2-56 UNC, use a bottoming chamfer for blind holes. Ensure the H4 / 2B-3B tolerance matches your required fit. Cobalt taps suit harder materials. Consult OSG's technical data for optimal speeds and lubrication.
