expanding hollow wall anchor

Self-drilling screws have a sharp point at the tip, designed to pierce through metal, wood, or plastic without requiring pre-drilled holes. This feature significantly reduces installation time and effort, thereby increasing efficiency on the job site. The thread of these screws is specifically designed to cut into the substrate, providing a strong and secure hold. They are particularly useful in situations where speed and convenience are paramount, such as in the assembly of furniture, automotive parts, or even in home renovation projects They are particularly useful in situations where speed and convenience are paramount, such as in the assembly of furniture, automotive parts, or even in home renovation projects They are particularly useful in situations where speed and convenience are paramount, such as in the assembly of furniture, automotive parts, or even in home renovation projects They are particularly useful in situations where speed and convenience are paramount, such as in the assembly of furniture, automotive parts, or even in home renovation projectsnylon head self drilling screws.

The primary structure of a wedge-type anchor consists of a threaded rod, a nut, a washer, and the wedge itself. The threaded rod, often made from durable materials like steel or stainless steel, is inserted into a pre-drilled hole. As the nut is tightened, the wedge is forced against the inner wall of the hole, causing the anchor to expand. This expansion generates a powerful frictional force that locks the anchor in place, providing exceptional holding power.
