Self drilling screw, also known as sheet metal screws or dovetail screws, are a type of high-hardness self-tapping screws. The unique drill tail or pointed tail design at the tail gives it the ability to directly screw into materials without pre-drilling holes. The powerful functions of drilling, tapping and locking greatly simplify the installation process and effectively save construction time and labor costs.The round-head, self-drilling screw with a (Phillips)-shaped drive and integrated washer is a versatile fastening solution.

Featuring a round head design, it allows for easy insertion and tightening into various materials such as wood, metal, and plastic. The integrated washer eliminates the need for a separate one, enhancing stability and load-bearing capacity. The Phillips drive ensures efficient installation with standard screwdrivers. Its self-drilling tip simplifies the process by drilling and tapping threads simultaneously, saving time and effort on pre-drilling.

Suitable for a wide range of applications, this screw offers a secure, reliable, and cost-effective fastening option.

Full-thread design: The thread covers most of the nail shank length, ensuring full engagement for a more secure fixation and stronger pull-out resistance.
Self-tapping thread: Sharp thread profile for fast tapping speed and low locking torque, making installation easier.
Fine-pitch thread: Closer pitch for tighter engagement with thin-walled metal plates, resulting in stronger pull-out and shear resistance.
Low-torque thread design: Optimized thread design reduces installation resistance and prevents material tearing or damage.
Large pressure-bearing area: The head diameter is larger than that of a standard round head, providing better pressure distribution and preventing damage to thin sheet materials during tightening.
Low profile design: The head height is low and slightly curved, resulting in less protrusion after installation and a smooth, aesthetically pleasing surface.
No surface damage: The wide head design reduces surface indentations or dents, making it particularly suitable for painted workpieces or those requiring a specific appearance.
Anti-slip: The wide head provides better tool contact area, ensuring greater stability during installation.
Wide head, low pressure, won’t damage surfaces; self-drilling eliminates the need for holes, saving half the labor. Specifically designed for metal frames/plasterboard/HVAC systems; C1022A heat treatment ensures no cracking. Low-profile and aesthetically pleasing design; large bearing area.
