expansion bolts for hollow structural steel sections

A tek screw, also known as self-drilling screw, is equipped with a drill-like point that allows it to create its pilot hole as it is driven into materials. This eliminates the need for pre-drilling, which can streamline the construction process significantly. The 5 designation typically refers to specific measurement protocols related to the screw's dimensions and strength characteristics. However, the specific meaning of 5 often involves manufacturer specifications or industry standards, allowing for slight variations in size and application based on regional or production practices.
