Self tapping screw and self drilling screw
Self-Tapping Screws (STS)
Self-tapping screws are designed to create their own threads as they are driven into a material. However, they usually require a pre-drilled hole before insertion. These screws are commonly used in metal, wood, plastic, and composite materials. They offer strong fastening with minimal effort and are ideal for applications where disassembly and reassembly may be necessary. The thread-cutting action provides a secure hold, preventing loosening due to vibration. Depending on the head type, they can be flush-mounted or provide extra holding power on the surface.

Self-Drilling Screws (SDS)
Self-drilling screws eliminate the need for pre-drilling by incorporating a drill bit tip at the end of the screw. They are mainly used in metal-to-metal and metal-to-wood fastening applications. These screws speed up installation and reduce the risk of misalignment by ensuring precise placement. Their hardened steel tips allow them to penetrate tough materials without additional drilling tools, making them highly efficient for industrial and construction projects.
