Features Company profile Certification & test
Flat Head Self Tapping Metal Screws are used when the fastener head needs to sit level with the surface. The original product name is M4.8 Countersunk Head CSK Self-Drilling Screws.
The page describes a pointed end, widely spaced threads, stainless steel material direction, flat head style, and Phillips drive. The flat / countersunk head allows a cleaner surface after installation, which is useful for panels, brackets, furniture metal fittings, and visible hardware parts.
The pointed end helps start the screw into the base material, while the thread profile supports self-tapping into suitable materials. Phillips drive can help reduce over-driving by cam-out behavior under high torque in some assembly conditions.
