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.

Self-tapping screws are designed to create their own hole as they are driven into materials, eliminating the need for pre-drilling. This feature significantly enhances the efficiency of installation processes, making them a popular choice among professionals and DIY enthusiasts alike. Available in different sizes and materials, self-tapping screws can be utilized in metal, wood, or plastic applications. Their ease of use and reliability make them ideal for a wide range of projects from home repairs to large-scale constructions.
