A hex head self-drilling screw, as the name suggests, combines the functions of a drill bit and a screw in one. It features a sharp point at its tip, designed to pierce through various materials without the need for a pre-drilled hole. The hexagonal head allows for easy handling with a wrench or socket, providing greater torque control during installation.

Self-drilling screws, also known as Tek screws or drill point screws, are a type of fastener designed to drill and tap their own holes as they are driven into the material. This makes them ideal for applications where drilling a pilot hole is not practical or possible. One popular size of self-drilling screws is the 150mm variant, which is commonly used in construction, metalworking, and woodworking projects.

Structural bolts are made from high-strength materials such as grade 5 or grade 8 steel, making them resistant to corrosion and wear. They are heat-treated to achieve the necessary tensile strength, which can range from 120,000 to 180,000 pounds per square inch (psi). This high-strength capacity is crucial for withstanding the dynamic forces and stresses that structures face over time, including wind, seismic activity, and the weight of the structure itself.
