How to select the correct OSG STI tap for a thread repair job?

To select the correct OSG STI tap, match the thread size and pitch (e.g., 1"-12 UNF) to the insert you will install. Use a bottoming chamfer for blind holes and a spiral-flute design for steel or stainless steel to evacuate chips. The H6 tolerance ensures proper thread class fit.
