THROUGH TAPPED SELF-TAPPING INSERTS

Through-tapped self tapping inserts offer a hybrid of Metric OD inserts and blind self-tapping inserts. They are shouldered, undercut and have metric internal threads. However the main difference that makes these inserts stand out is the external threads are a 30 degree self-tapping form with a three notch cutting relief that work in a similar way as the blind self-tapping inserts. For non standard threaded inserts, please contact our manufacturing team for details.
