The anti-slip self-drilling screw is precision-forged from high-hardness carbon steel. Its tail features a spiral self-drilling design, which can directly penetrate base materials such as metal and wood without pre-drilling, improving installation efficiency by more than 50%.
It is doubly enhanced by a unique serrated anti-slip thread and a cross anti-slip slotted head, which effectively prevents slipping and thread stripping during twisting, ensuring long-term tightness without loosening.
The surface is treated with hot-dip galvanizing or Dacromet, providing salt spray resistance and rust resistance, making it suitable for various scenarios such as outdoor guardrails, color steel tiles, and photovoltaic brackets.It comes in specifications of 5.5mm, 6.3mm, and 8mm to meet the needs of base materials with different thicknesses. It is an efficient anti-slip fastening choice in the fields of construction, decoration, and equipment installation.
