As self-tapping screws, High Strength Cross Recess Fiberboard Screws are equipped with a special self-tapping thread design. The thread pitch is precise, the thread profile is optimized, and the tip is sharp and wear-resistant. When in use, there is no need to pre-drill holes on the fiberboard or other materials; the screws can be directly screwed into the material by virtue of the self-tapping force generated by the thread, which greatly improves the installation efficiency and reduces the construction difficulty. At the same time, the thread design has strong gripping force, which can closely fit the internal structure of the fiberboard, effectively preventing the screws from loosening due to vibration, temperature changes or long-term use. The high-strength performance of the screws allows them to bear greater tensile force and shear force, and they are not easy to break or deform even under heavy load, ensuring the stability and safety of the connection structure.
