1. Time Efficiency The self-drilling capability eliminates the need for pre-drilling, saving considerable time during installation. This makes them ideal for situations where speed is essential, such as in large-scale construction projects.

4. Durability Made from materials such as stainless steel, zinc-plated steel, or other corrosion-resistant materials, expandable anchors are designed to withstand environmental factors. This durability ensures that they maintain their integrity over time, even in harsh conditions, making them a long-term solution for anchoring needs.

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.

- Size and Thread Type Choose the appropriate size and thread type based on application requirements, including load-bearing specifications.
