Cross Countersunk Tapping Screws

Cross countersunk tapping screws are self-tapping screws, mainly used for woodworking and metal connections. The head is designed as a countersunk head, and after tightening, the screw head is completely embedded in the material surface and not exposed. This design is suitable for threaded connections between thin metal sheets (such as aluminum, copper, and low-carbon steel) and thicker metal parts or wood products. It can be directly screwed in to form threads without pre-drilling. In addition, cross countersunk tapping screws are widely used in architectural decoration, door and window curtain wall fasteners and other fields. The materials include carbon steel, stainless steel, etc., and the specifications are diverse.
