These zinc plated and hardened self tapping screws are designed for efficient assembly of metal or wood components. They are commonly used in sheet metalworking and the construction industry for building steel frames, wooden floors, roof decks, and doors. These screws tap their own threads, requiring only a pilot hole for installation. For many everyday gadgets with plastic parts, the pilot hole comes pre-drilled, simplifying assembly. The countersunk profile ensures a neat, flush finish without any protruding parts. Featuring a Pozidriv-type head, these screws allow for high torque, leading to quick and secure installations. The zinc plating provides excellent corrosion resistance, making them suitable for both indoor and outdoor applications.
