3. Material Quality The material of the butterfly screws can affect durability and performance. Look for screws made of high-quality metal, such as stainless steel, to avoid corrosion and ensure longevity.

1. Efficiency The primary advantage of Tek screws lies in their ability to self-drill. This feature significantly reduces installation time, as workers do not have to pre-drill holes. This efficiency translates to cost savings on labor and time, making them an attractive option for contractors.

The mechanical properties of A325 fasteners include a minimum yield strength of 80 ksi and a minimum tensile strength of 120 ksi, ensuring they can handle the demanding conditions often found in structural applications.
