Product Description
Self-drilling screws are usually classified as self-tapping screws and are often called drill tail screws or self-tapping and self-drilling screws in daily life. Their tails are like drill bits and can drill holes by themselves. They can directly penetrate into the connected materials without the need for pre-drilling, thus greatly saving construction time.
Carbon steel: Commonly used, with a surface hardness of HV560 - 750 and a core hardness of HV240 - 450 after standard heat treatment. However, it is prone to rusting with ordinary surface treatments2.
Stainless steel: Self-drilling screws made of stainless steel have excellent anti-corrosion properties. For example, those made of 304 stainless steel have strong rust prevention capabilities, but they cannot be heat treated, have relatively low hardness, and higher costs. They are often used in environments with high requirements for corrosion resistan
Head Shapes: Commonly seen head shapes include countersunk head with cross slot, pan head with cross slot, pan head with Phillips slot, slotted pan head, slotted countersunk head, hexagon head with washer face, etc1.
Slot Types: There are multiple options such as cross slot, slotted, and Phillips slot.
| Diameter | Self-tapping screws have a variety of diameter specifications. Commonly seen ones include M1.0, M1.2, M1.4, M1.6, M2.0, M2.5, M3.0, M3.5, M4.0, M5.0, M6.0, etc. |
| Length | The length range is usually from 1.5 mm to 100 mm, such as 3 mm, 5 mm, 8 mm, 10 mm, 12 mm, 16 mm, 20 mm, 25 mm, 30 mm, 40 mm, 50 mm, etc. |
| Thread Parameters | They can be divided into coarse threads and fine threads. Coarse threads have a larger pitch, enabling faster penetration but relatively lower fastening force. Fine threads have a smaller pitch, are more difficult to penetrate but can provide greater fastening force, suitable for occasions where higher connection strength is required. |

Self-Drilling Function: It can drill holes by itself, saving construction time and improving work efficiency.
Powerful Fastening Force: It can provide reliable fastening to ensure the stability of the connection.
Wide Range of Applicable Materials: It can be used for various materials such as metal, wood, and plastic.
Multiple Head Shapes and Slot Types: Different head shapes and slot types are available to meet different usage requirements and aesthetic needs.
Diverse Surface Treatments: Different surface treatments can be selected according to different usage environments to improve the anti-corrosion and wear resistance of the screws.
