How to select the correct STI tap size for a thread repair?
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.
