Self Drilling Security Screws
Weight Range ： 0.5g–500kg
Materials: Carbon steel / Mild steel / Structural steel / Stainless steel / Aluminum / Copper, etc.
Self Drilling Security Screws can be drilled, tapped and fastened simultaneously. They effectively prevent disassembly and significantly improve construction efficiency. This screw does not require pre-drilling and is suitable for a variety of materials and occasions. It can greatly save installation time and reduce labor costs.
Its head is equipped with a variety of anti-tamping designs, such as one-way, three-wing, snake, pentagonal or lug-type structures. These special designs prevent unauthorized disassembly of ordinary tools. They are ideal for high safety requirements such as public facilities, power housings and mechanical equipment.
We strictly control the manufacturing quality and keep the dimensional tolerance within ±0.1mm. This ensures reliable fit for each screw. We galvanize the surface of our products and provide excellent corrosion resistance. They pass salt spray tests over 96 hours and maintain stable performance and integrity for a long time even in humid or corrosive environments. Therefore it becomes ideal for safe and durable fastening solutions outdoors and harsh environments.

Classic combination
Metal Sheets + Self Drilling Security Screws
Screws penetrate directly through the metal sheet and cut firmly into the base bracket. It efficiently completes the complete drilling, tapping and locking process, greatly improving the construction speed of exterior walls and partition walls.
Its special anti-tear head design can effectively prevent the reverse operation of ordinary tools, providing reliable anti-theft protection for public facilities, and at the same time, the galvanized coating on the surface ensures its long-term corrosion resistance in outdoor environments.
Grounding terminal piece + self-drilling safety screw
Screws firmly fix the stamped grounding terminal piece to the equipment box or metal structure. It can quickly form a reliable electrical grounding path without pre-drilling to ensure system safety.
Its safety head design prevents unauthorized personnel from easily dismantling, thus maintaining the integrity and permanence of ground connections, and is especially suitable for power or communication rooms that need to meet strict safety regulations.
Ventilation Mesh Panels + Self Drilling Security Screws
Screws easily install stamped ventilation mesh panels onto the chassis, cabinet doors or equipment housings.
While providing efficient air circulation, its anti-theft characteristics prevent unauthorized disassembly and protect internal critical equipment from interference or theft.
The screws' excellent corrosion resistance also ensures that they can maintain a stable connection and a complete appearance even in the face of humid environments during long-term use.
Equipment Enclosures + Self Drilling Security Screws
Screws are responsible for quickly assembling various components of the equipment box and fastening the access panel.
It simplifies the installation process with its self-drilling and self-attacking characteristics, and its anti-tearing function ensures that only authorized personnel can open the box and effectively protect internal components.
This makes it an ideal fastening option for outdoor cabinets, power facilities and other high safety requirements, taking into account installation efficiency and long-lasting safety.
