These used Cross Recessed Countersunk Head Carbon Steel Black Zinc Plated Self-Tapping Screws (M3) come in a 12-piece pack, ready to fasten small assemblies with confidence. The combination of a countersunk head, a Phillips drive, and a self-tapping thread delivers a clean, flush finish and fast installation for a variety of projects.

• Drive and head: cross recessed (Phillips) drive for secure engagement with standard screwdrivers; countersunk head sits flush to the surface.
• Material and finish: carbon steel core with a durable black zinc plating that provides corrosion resistance in typical workshop environments and a discreet, satin finish.
• Size and fit: M3 diameter; designed for light-duty, precision assemblies in plastics, thin metals, and soft materials where a self-tapping screw is appropriate.
• Pack and condition: 12 screws in each pack; used condition, inspected for thread integrity and overall usability for reliable performance in ongoing projects.
• Ideal applications: electronics enclosures, hobbyist projects, DIY plastic or metal housings, small appliance repairs, and other precision fittings where a flush, low-profile fastener is desired.
• Installation tips: use the correct pilot hole for the material, and drive to a snug fit without over-torquing to prevent thread stripping; these screws work well in soft plastics and thin metal panels when pre-drilled or pre-tapped as appropriate.

Whether you're assembling a budget electronics project, repairing a lightweight enclosure, or prototyping a new idea, this 12-pack of M3 cross recessed countersunk self-tapping screws is a practical, value-focused choice. The used condition keeps costs down while delivering dependable performance for non-critical assemblies.
