Back To Top
    • 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 hole
