Drill tail screws can be integrated with self-drilling, self-tapping, and locking, and are widely used in steel structure factories, color steel tiles, photovoltaic brackets, guardrails, aluminum alloy and plate fastening, with efficient construction without the need for pre-drilling. The mainstream materials are 1022A carbon steel, 410 stainless steel, and 304/316 stainless steel. Carbon steel has a high cost-performance ratio, 410 combines hardness and rust prevention, and 304/316 is corrosion-resistant and suitable for outdoor and coastal environments. The commonly used strength grades are 4.8 and 8.8, with stainless steel corresponding to A2-70. Hardness standard: HRC28-40 for the core and HRC40-50 for the surface of the drill tail, ensuring that the drill hole does not collapse or the threads do not slip, meeting the requirements for rapid fastening and long-term load-bearing of metal plates.
