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

To select the correct OSG STI tap, match the thread size (e.g., M3x0.5) and tolerance class (D2 / 4H-6H) to your insert requirements. For steel or stainless steel blind holes, choose a spiral-flute design. Always verify the tap is for STI (screw thread insert) use, not standard threading.
