In addition to their efficiency and practicality, self-drilling screws also boast superior holding power and corrosion resistance. The sharp threads and self-tapping design create a tight and secure grip, preventing the screws from loosening or pulling out over time. Furthermore, most self-drilling screws are made from high-quality materials, such as stainless steel or hardened steel, that offer excellent resistance to rust and corrosion. This ensures that the screws maintain their strength and integrity even in demanding environments or harsh weather conditions.

The primary function of wedge bolts is to firmly attach the wooden or metal forms to the concrete foundation or structural steel. This ensures that the forms maintain their position during the pouring and setting of the concrete, preventing any displacement or leakage that could compromise the integrity of the structure. The bolts' ability to withstand high tensile forces is critical in withstanding the pressure exerted by wet concrete and the subsequent curing process.
