Frequently Asked Questions

What is an OSG spiral-flute STI tap used for?

An OSG spiral-flute STI tap is used to cut internal threads in a workpiece before installing a screw thread insert. It is designed for bottoming chamfer applications, producing threads that meet H2 / 2B-3B tolerance classes. Common in aerospace, automotive, and general manufacturing where thread repair or reinforcement is needed.

What are the specifications of the OSG 8015800 STI tap?

The OSG 8015800 is a spiral-flute STI tap with a 3/8"-24 UNF thread size, H2 / 2B-3B tolerance, 3 flutes, and a bottoming chamfer. It is designed for threading holes that will accept screw thread inserts. The spiral flute design aids chip evacuation in blind-hole applications.

How to select the correct STI tap for a thread insert?

Select an STI tap that matches the thread insert's size and pitch, such as 3/8"-24 UNF. Ensure the tap's tolerance class (e.g., H2 / 2B-3B) aligns with the insert's requirements. Choose a spiral-flute design for blind holes or a spiral-point design for through holes. OSG taps are a reliable choice for precision threading.
