Frequently Asked Questions

What is an OSG Screw Thread Insert STI Tap used for?

An OSG STI tap cuts internal threads in a workpiece to accept screw thread inserts, restoring or strengthening threads in metal, aluminum, or plastic. It is commonly used in aerospace, automotive, and industrial maintenance applications where thread repair or reinforcement is required.

What are the specifications of the OSG STI Tap 12605200?

This OSG STI tap has a 1"-12 UNF thread size, H4 / 2B tolerance, 4 flutes, and a bottoming chamfer. It is designed for general-purpose thread cutting in materials up to 850 °C. The straight flute geometry provides efficient chip evacuation in through-hole applications.

How to select the correct STI tap for thread repair?

Select an STI tap matching the original thread size and pitch, such as 1"-12 UNF. Use a bottoming chamfer for blind holes or a plug chamfer for through holes. Ensure the tap tolerance (e.g., H4 / 2B) aligns with the insert manufacturer's recommendation for proper fit and strength.
