Frequently Asked Questions
What is an OSG Screw Thread Insert STI Tap used for?
An OSG Screw Thread Insert STI Tap is used to cut internal threads in steel and stainless steel for installing helical wire thread inserts. It is commonly applied in aerospace, automotive, and industrial maintenance to repair or reinforce threaded holes without replacing larger components.

The OSG 30201108 is a spiral-flute STI tap with thread size 1/4"-20 UNC, H3 / 2B-3B tolerance, and 3 flutes. It is designed for tapping steel and stainless steel. The spiral flute design helps evacuate chips upward, making it suitable for through-hole applications.

How to select the correct STI tap size for a thread insert?
Select an STI tap that matches the thread insert's nominal size and pitch, such as 1/4"-20 UNC. The tap tolerance (e.g., H3 / 2B-3B) must align with the insert's internal thread class. Always refer to the insert manufacturer's recommendations and use a tap designed for the base material, like OSG's spiral-flute taps for steel.
