What is a self-tapping screw? In the usual sense, a self-tapping screw is a threaded fastener that does not need a pre-tapped internal thread. When the screw is driven into a smooth, untapped hole, it cuts its own internal thread, so a relatively high torque is required. The mating part is normally a soft material such as plastic or an aluminum/magnesium alloy. Self-tap...
In the blow-feed structure of existing blow-type screw feeders, a feed tube is usually used as the conveying channel for screws.
