Zinc plated, hardened. Save time while assembling metal or wood components using these self-tapping screws. They are typically used in the sheet metalworking and construction industry for building steel frames, wooden floors, roof decks and doors. These screws tap their own threads, so you only need to drill a pilot hole before inserting the screw. In many everyday gadgets with plastic components, the pilot hole comes pre-drilled so you can simply use a self-tapping screw like this one during assembly or for fixing accessories. The screws feature a countersunk profile, so they will sit flush on the surface. This ensures a neat finish without any potentially dangerous protrusions sticking out of the frame. A Pozidriv-type head ensures you can achieve high torques for quick and secure installations. Zinc plating on the screws ensures it is corrosion-resistant, so you can use it for indoor and outdoor applications. These screws are zinc-plated for corrosion resistance and outdoor use.
