304 316L Stainless Steel Trim Head Screws for Metal Studs Self Tapping Wood Screws Product：

Self tapping screws are more common in the daily link of thin metal plate (steel plate, saw plate and so on). Due to the high strength of the thread surface of the tapping screw (≥HRC45), so when linking, screw the tapping screw into the connection piece which is made out of the thread bottom hole in advance, so that the inner thread can be tapped out of the thread bottom hole of the link piece to complete the connection.

There are special types of tapping screws that work better than ordinary tapping screws and can even replace machine screws - tapping pin tightening screws are often used for connections between thin metal plates. The difference between it and the common tapping screw is that it has a higher hardness of the arc triangle interface of the common thread. This excellent screw with low insertion torque and high locking performance can, of course, tap the inner thread in the bottom hole of the thread to be connected just like a normal screw.
