OSG Screw Thread Insert STI Tap: Spiral Point, 3/4"-10 UNC, H5 / 2B-3B, 3 Flute

An OSG Screw Thread Insert STI Tap cuts internal threads in steel and stainless steel to accept helical wire thread inserts. It is commonly used in aerospace, automotive, and heavy equipment repair where stripped threads must be restored to original strength without replacing the parent component.

The OSG 30103601 is a spiral-point STI tap with 3/4"-10 UNC thread, H5 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is designed for threading holes that will receive screw thread inserts in steel and stainless steel. The spiral-point design pushes chips forward for through-hole applications.

Select an STI tap that matches the original thread size and pitch, such as 3/4"-10 UNC. The tap must be marked for screw thread insert use, not standard threading. Always verify the insert manufacturer's recommended tap drill size and tolerance class (e.g., H5) to ensure proper insert fit and thread strength.
