Self-drilling screws have become a popular choice for many construction and engineering projects due to their convenience and efficiency. These screws eliminate the need for pre-drilling a hole before inserting them, saving both time and effort. One type of self-drilling screws that is commonly used is the 4% self-drilling screw.

4. Corrosion Resistance The black phosphate coating not only provides a sleek finish but also protects the screws from rust and corrosion. This is crucial in regions with high humidity or in applications where moisture may be a concern, ensuring that the integrity of the assembly remains intact over time.

One of the primary advantages of T-head screws is their excellent load distribution capabilities. The broad head design reduces the risk of damage to the material being fastened, ensuring a secure grip without compromising the integrity of the substrate. Moreover, the shape of the T-head prevents the screw from turning when tightened, enabling efficient and straightforward installation.
