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 tapped holes without replacing the parent material.

What are the specifications of the OSG 30102408 STI Tap?

The OSG 30102408 is a spiral-point STI tap with a 1/2"-20 UNF thread, H3 / 2B-3B tolerance, 3-flute design, and plug chamfer. It is designed for threading holes that will accept screw thread inserts in steel and stainless steel workpieces.

Where to buy OSG STI Taps worldwide?

3G Electric supplies OSG STI Taps worldwide, handling full logistics and customs clearance for international orders. As a global industrial sourcing partner, we provide genuine OSG cutting tools like the 30102408 to customers across multiple industries, ensuring compliance with export requirements.

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 1/2"-20 UNF. The tap tolerance (e.g., H3 / 2B-3B) must align with the insert's class fit. Always verify the tap's chamfer type—plug chamfer suits most general applications—and ensure it is rated for the workpiece material, like steel or stainless steel.
