These screws are typically made from high-carbon steel or stainless steel, ensuring durability and reliability. The design features a drill point that allows the screw to penetrate through various materials—metal, wood, and even some composites—while simultaneously creating a snug fit as they are installed.

Tek screws, also known as self-drilling screws, are specially designed fasteners that eliminate the need for pre-drilling holes in the materials being joined. They feature a drill point at the tip, allowing the screw to penetrate and create its own hole as it is driven into the material. The term Tek is derived from the brand name of a popular series of self-drilling screws, but it has become a generic term within the industry.

In the realm of engineering and construction, the importance of fasteners cannot be overstated. Among the various types available, hex head bolts and nuts play a critical role due to their unique design and functionality. This article explores the characteristics, uses, and advantages of these essential components.
