The design features of the countersunk head sharp point self-tapping screws enable them to form threaded holes directly on the surface of the material, thereby achieving quick installation. This product complies with multiple international standards such as DIN 7982, ISO 15482 and ASME/ANSI B 18.6.4. The materials include C1022A, SUS410, SUS304 and SUS316 stainless steel, and the specifications range from ST3.5 to 1/4 inches to meet the needs of different scenarios.
The head of the countersunk head and pointed tail self-tapping screw is designed as a countersunk head, and the tail is a pointed tail structure, which is convenient for forming a flat installation surface on the surface of the material while ensuring the fixing effect of the nail.

These treatments not only improve the corrosion resistance of the product, but also enhance the aesthetics and durability.
The product specifications are diverse, ranging from ST3.5 to ST6.3 and thinner models such as 6#, 7#, 8#, 10#, 12#, 14#, etc., which can meet the fixing needs of materials of different thicknesses. The groove design is usually a cross groove or a hexagonal groove, which further enhances the flexibility of use.
