Ordinary Discount Double Sided Screw - Cross sink self-drill screw – Tiancong

Product Description

The difference between the self-drilling self-tapping screw and the ordinary self-tapping screw is connected through the two processes of drilling (drilling thread bottom hole) and tapping (including tightening connection); when the self-drilling self-tapping screw is connected, the drilling and tapping screw are combined once.
