Need some sturdy screws for a woodworking project? This pack of 50 SKIR'CO self-tapping screws is handy to have around. They're 4.2mm in diameter and 19mm long, fully threaded, with a PH modified truss head (that's like a washer head) in a graphite grey color (RAL 7024). The zinc plating helps prevent rust, so they're good for indoor use and maybe some outdoor projects if not exposed to heavy weather. The sharp point makes them easy to start, and they work in all kinds of wood – solid wood, plywood, MDF, chipboard, you name it. You can also use them to attach thin metal or plastic sheets to wood. They come with a suitable screwdriver bit, which is a nice touch. The wide head gives good clamping force without sinking too deep. Great for DIY furniture, shelving, repairs, or even light construction. They're reliable, easy to use, and the grey color is less noticeable than silver screws if that matters to you.
