CSK SELF TAPPING SCREW FLAT HEAD 4.2MM X 38MM (1000PCS/BOX)

CSK (Countersunk) Self-Tapping Screw with Flat Head is designed for applications where a flush finish is needed. These screws tap their own threads into materials such as wood, plastic, or soft metals without the need for a pre-drilled hole. The flat head allows the screw to sit flush or below the surface for a clean and smooth appearance, making it ideal for projects where aesthetics are important. Commonly used in cabinetry, furniture assembly, and general construction, these screws offer both durability and ease of installation.
