Cross Recessed Countersunk Head Self-Tapping Screws

This Cross Recessed Countersunk Head Self-Tapping Screws is made of  304 stainless steel. Its surface has undergone blackening and passivation treatment, which is different from the common blackening achieved through spraying paint. The coating has strong adhesion and is not prone to fading or peeling. The screw comes with a pointed tail self-tapping thread, eliminating the need for pre-drilled threaded holes. It can directly penetrate the material through its own thread pattern for fastening. The sink-in structure can fully sink into the workpiece, resulting in a smooth and seamless surface after installation. It combines rust prevention performance with a matte black appearance, and is suitable for various indoor and outdoor concealed fastening needs.

Product Feature

The core advantage of this screw lies in the combination of stainless steel base material and black surface treatment. The stainless steel material offers excellent rust and corrosion resistance, capable of coping with humid, outdoor and weak acid-base environments. Its service life is much longer than that of ordinary galvanized screws. The countersunk design ensures that it fits flush with the surface of the workpiece after being screwed in, which not only guarantees a flat and aesthetically pleasing installation surface but also avoids the risk of scratches caused by protrusions. The cross-slot is compatible with a regular screwdriver for quick operation. The self-tapping tooth pattern can directly drill out threads on thin metal plates, plastics or woods, eliminating the need for pre-drilling and improving assembly efficiency. The black surface treatment not only meets specific color matching requirements but also has certain lightening and wear-resistant effects, making the overall appearance more textured.
