1. Material Composition The “1% 201% 4%” typically indicates a specific ratio of metals used in the alloy, such as stainless steel or another corrosion-resistant material, which enhances durability. Stainless steel screws resist rust and corrosion, making them ideal for settings exposed to moisture or chemicals.

The self-drilling aspect of these screws implies that they come equipped with a sharp, drill-like tip that enables them to pierce through materials without the need for pre-drilling a pilot hole. This feature significantly speeds up the installation process and reduces the risk of damaging the material being used. Self-drilling screws are often made from durable materials, such as stainless steel or carbon steel, and are coated with various finishes to enhance corrosion resistance and longevity.

An M6% resin anchor is a type of fastener designed to be embedded into a substrate, primarily concrete, using a high-strength resin adhesive. The M6 designation refers to the metric thread size; this means that the anchor has a nominal diameter of 6 millimeters. The % indicates that the resin is formulated to perform effectively under various conditions, enabling a secure bond regardless of the environment. This type of anchor is ideal for applications requiring substantial load-bearing capacity while maintaining a non-corrosive and durable bond.
