Thread forming screws AB and B, shown in Fig. 9.01 are fast driving, spaced-thread screws. The BP screw is much the same as the B screw except that it has a 45° included angle and unthreaded cone points. The cone point is useful
Tap-Flex Thread-Forming Structural Screws
anchors.dewalt.comEnhanced Thread Design Tap-Flex screws are threadformers with the patent-pending E-Form® segmented thread profile. This design improves both installation and in-place performance: • Decreases thread-forming torque, easing starting and placement • Overcomes friction build-up and reduces drive torque • Increases thread engagement, so it

4. Manufacturing screws and nuts
www.wuerth-industrie.comWhere screws are mass-produced, the thread is usually formed or rolled. In this procedure, the screw is rolled between two rolling dies (flat dies), one of which is fixed and the other running, and this creates the thread (see the diagram). With this type of thread production it is possible to fit several hundred screws per minute with a thread.
