This screw is primarily used for fastening thicker and harder metal sheets. Its threads feature a cutting groove and three chip clearance slots. The cutting groove helps the screw penetrate materials more easily, reducing driving resistance and improving installation efficiency. The chip clearance slots quickly expel debris generated during fastening, preventing clogging, reducing friction and heat buildup, which greatly extends the screw’s service life.
Due to the enhanced design and manufacturing complexity, the production cost of this screw is higher, so it is reserved for special applications. If you have any needs, please feel free to contact us. We look forward to the opportunity to cooperate.
