Self-drilling bolts feature a unique point design that allows them to pierce through materials such as metal, wood, and plastics. The shaft of the bolt is crafted to have threads that grip the material securely once the bolt is installed. This eliminates the need for pre-drilling, saving time and labor costs. The design often includes a cutting tip that facilitates penetration and minimizes damage to the surrounding material, ensuring a clean and reliable connection.

Furthermore, fully threaded bars offer excellent corrosion resistance, making them a durable and long-lasting solution for construction projects. Unlike plain steel bars, which can rust and corrode over time, fully threaded bars are coated with a zinc layer that provides effective protection against corrosion. This means that these bars can withstand the harsh conditions commonly found in construction sites, ensuring that the structure remains intact for many years to come.
