The key feature of long self-drilling screws lies in their unique. Unlike conventional screws, they possess a sharp point and a series of cutting edges that cut through material like a drill bit. This makes them ideal for use in a wide range of materials, from wood to metal, plastic, and even composite materials. Their length, often extending beyond the standard size, enables them to penetrate deeper into substrates, providing superior holding power and structural integrity.

Chemicals, on the other hand, play a vital supporting role in the functionality of anchor fasteners. Chemical anchor systems, such as epoxy resins and urethane adhesives, offer a more versatile and reliable alternative to traditional mechanical anchors. These chemicals, when mixed, form a strong bond with the substrate, providing superior load-bearing capabilities and resistance to environmental factors like moisture and temperature changes. They are particularly useful in situations where drilling is difficult or impossible, or when a high degree of precision is required.
