Abstract

This product is a self-drilling screw with a male thread formed on the conical surface below the countersunk head. As shown in the reference diagram illustrating the usage, for example, a steel plate is placed on top of a square pipe-shaped frame, and the self-drilling screw of this product is screwed into the steel plate from above. In this way, the drilling part at the tip drills into the steel plate and the frame, the thread is screwed into the drilled hole, and the male thread formed on the conical surface below the countersunk head screw-connects to the steel plate and the frame.
