The tail of the truss head self-drilling screw is drill-tailed or pointed-tailed, which does not require auxiliary processing. It can directly drill, tap and lock on the setting materials and foundation materials, which greatly saves construction time. Compared with ordinary screws, the self-drilling screws have higher toughness and maintaining force, and the long time after combination is not loose. The use, safe drilling and tapping are completed at one time, and the operation is simple.

Truss self-drilling screws are usually used in industrial or daily use. When purchasing truss head self-drilling screws, we should pay special attention to the corrosion resistance and anti-rust treatment of boring head self-drilling screws. The oxidation method can be applied separately, surface treatment, and its function is to form a separate film on the surface of the metal, usually a compound of oxygen and metal, preventing the metal from directly contacting the corrosive medium.
The boring head self-drilling screw is inspected for inventory check. Classified according to the product specifications and batch numbers indicated on the package, and establish an inventory schedule and issue registration form. Work well against moisture and dust. The bottom layer is at least 30cm away from the ground and at least 30cm away from the wall to ensure ventilation and moisture, and to prevent surface conditions and corrosion of the self-drilling screw of the truss head. Do not open the box at will during the storage period. Prevent the boring head self-drilling screws from rusting or contaminating the dirt, and ensure the original surface treatment condition of the bolts, nuts and washers, and the torque coefficient does not change. Unpacking before use. If the boring head self-drilling screw is exposed in the air, especially if it is exposed for a long time on the bridge before being screwed, it will definitely cause the torque coefficient to change.
