Square Drive Self Tapping Screws
Weight Range ： 0.5g–500kg
Dimensional tolerance ： ±0.1mm
Square drive self tapping screws are the epitome of efficiency and reliability in modern fastening operations. Its unique square drive design can increase torque transmission efficiency by nearly 50%. This fundamentally eliminates the slipping problem of traditional grooves and protects the screws and bits. In actual construction, it can increase the overall installation efficiency by 20 to 30%. At the same time, the Type 17 tip equipped with high-quality products can reduce the introduction resistance by up to 70%. This enables efficient pre-drilling installation.
Its long-term performance is equally excellent. The sturdy square head notch design allows the torque transmission capacity to remain at more than 95% after five disassembly and reassembly. This ensures ease of maintenance. With advanced surface treatments, these screws provide over five hundred hours of neutral salt spray protection. Therefore, it can maintain corrosion resistance and structural integrity in harsh environments, making it a safe choice for outdoor and heavy-duty structures.

Drawing Design & Confirm
Obtain drawings from clients or produce drawings based on their samples or specifications.
The drawings, product raw materials, surface treatment, and other details are attested to by both parties.
Advantages
Excellent anti-skid ability
The square head design increases the contact area by approximately 30%. It meshes with the batch mouth with almost no play. Tests have shown that the torque it can withstand is nearly 50% higher than that of traditional cross recesses. This effectively avoids slipping or "circling".
During installation, workers can safely use power tools to work at high speeds. No need to worry about the screws being damaged by idling. The overall installation efficiency is thus improved by about 20-30%. This advantage is particularly prominent in high-volume operations.
Excellent chip removal ability
High-quality products often use Type 17 planing tips. It's like a miniature drill. This design can reduce introduction resistance by up to 70%. It cuts and expels wood chips efficiently.
In most cases, this eliminates the need for pre-drilling holes. It not only saves drilling time and tool costs, but also avoids connection problems caused by pre-drilling deviations. Installation is more straightforward and connection is more reliable.
Good reusability
Square head notches are very wear resistant. Even after disassembly and reinstallation, its driving performance is still good. Tests have shown that after 3-5 complete screwing-in and screwing-out cycles, the maximum torque transmission capacity decreases by typically less than 5%.
At the same time, its threads can firmly engage the substrate. The possibility of loosening under vibration and long-term load is very low. This ensures a long-lasting and stable connection.
Controllable preload
The square head design allows greater mounting torque to be applied. Builders don't need to worry about notch damage. This allows the screw to generate and maintain a higher pre-tightening force, pressing the connection tightly together.
For example, when fixing hardwood floors, it can easily reach more than 95% of the specified installation torque. This ensures even and consistent clamping force on each screw. This controlled preload is key. It can effectively prevent wood cracking, loose joints and abnormal noise.
why choose us
Excellent anti-skid performance
- The square notch fits closely with the batch nozzle and has a large contact area, which fundamentally solves the problem of cross grooves or slots being easy to slip and be damaged.
Not easy to loosen
- Combined with high preload force and reliable thread engagement, it can maintain tightness for a long time under dynamic loads, making the connection more durable and stable.
Extended service life
- The stress is distributed evenly, which greatly reduces abnormal wear of the batch nozzle. The number of screws that can be installed in a batch nozzle is several times that of a traditional batch nozzle.
Reusable
- The groove is strong and wear-resistant, and even after several disassembly and reassembly, it can still maintain good driving performance and facilitate maintenance.
