High-strength self-tapping screw with triangular locking thread, designed for thread-forming in pre-drilled holes without tapping. The pan head provides a larger contact area for even load distribution, while the Phillips drive ensures easy and efficient installation. Made from carbon or alloy steel with advanced anti-corrosion coatings, it offers strong anti-loosening performance and durability in vibration and harsh environments. Widely used in automotive, electronics, furniture, and metal or plastic assemblies.
