heavy duty expansion anchor

A wafer head screw, as the name suggests, has a flat, thin, and circular head, resembling a wafer. The head is usually larger than the screw's body, providing a broad bearing surface that distributes the load evenly and reduces the chances of damage to the material being fastened. The self-tapping attribute refers to the screw's ability to cut its way through the material it is inserted into, forming threads as it goes, hence the term self-tapping.

Steel, being a material of choice for many construction projects due to its high strength-to-weight ratio, can be effectively reinforced with cross bracing. This system not only adds stiffness to the structure but also redistributes loads, preventing excessive deformation under stress. In essence, cross bracing acts as a tension-compression member, counteracting horizontal forces by creating a tension force in one direction and compression force in the other.
