Use and selection
This is the pointed self-tapping type with a flat head and under-head serrations. The receiving material and hole preparation are central enquiry inputs: state whether holes already exist and provide their dimensions where specified. Keep the required thread and head geometry on the drawing so the pointed type is not confused with a similar-looking drill-point screw.

Compare the configuration
Flat Head Self Drilling Screw with Under-Head Serrations identifies a self-drilling point instead. Choose the point type to match the receiving material and the specified hole preparation. M6 Needle Point Screw is a separate needle-point framing reference with an expressly pre-punched-hole context.
