- Features
| Designed for use in aluminum, magnesium, and other nonferrous materials where taps of this type are most commonly used |
| Taps suitable for other materials can be furnished on request |
| STI taps are dimensionally oversize and utilize a larger tap drill size so that the thread they produce will accept a helical coil wire screw thread insert of the same nominal size and pitch |
| For a particular size and pitch the lower H-Limit number is suggested for class 2B and 3B threads, while the higher H-Limit is suggested for class 2B |
| Through or blind hole |
