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 stripped threads without replacing the parent component.

What are the specifications of the OSG STI Tap 30201708?

The OSG STI Tap 30201708 is a spiral-flute tap for steel and stainless steel. It has a thread size of 3/8"-24 UNF, a thread limit of H2 / 2B-3B, and 3 flutes. The spiral flute design helps evacuate chips upward, making it suitable for blind-hole threading.

Where to buy OSG STI Taps worldwide?

You can source OSG STI Taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the OSG 30201708 or other OSG threading tools.

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

To select the correct OSG STI Tap, match the tap thread size and pitch to the insert you will install. For steel or stainless steel, choose a spiral-flute tap like the 3/8"-24 UNF model for blind holes. Verify the thread class (e.g., H2 / 2B-3B) matches your required fit tolerance.
