2. Strong Hold Tek screws provide a robust connection, ensuring that cladding materials remain securely fastened. Their design allows them to create strong threads in the substrate, which prevents loosening over time due to temperature fluctuations or structural movement.

The term 2% self-drilling screws generally refers to a specific classification or standard that adheres to a manufacturing specification, often denoting the composition or performance traits of the screws. The 2% might relate to various factors such as the percentage of alloying elements in the material, or guidelines that measure performance under certain conditions. For instance, these screws might contain 2% alloying elements that enhance their strength and corrosion resistance.
