About this item

  • PREMIUM 304 STAINLESS & BLACK FINISH: Stop compromising between durability and aesthetics. Unlike common alloy steel black screws that rust easily, LUKAISEN combines high-grade 304 stainless steel with a sleek black coating. Perfect for professional-looking projects that require long-term corrosion resistance in humid environments.
  • COMPREHENSIVE 820PCS METRIC KIT: One box to solve all your fastening needs. This assortment includes M2, M3, and M4 button head socket cap screws in various lengths, along with matching nuts, flat washers, and spring washers. Total 820 pieces ensure you always have the right size for RC cars, 3D printers, or drone repairs.
  • REINFORCED HEX SOCKET DRIVE: Say goodbye to stripped heads. Our screws are precision-machined with deep hex sockets to ensure a secure fit with your Allen wrench. The button head design provides a wider bearing surface and a low-profile, clean finish for your most delicate DIY electronics or furniture projects.
  • ORGANIZED & CLEARLY LABELED CASE: No more mixed-up hardware. All 820 components are housed in a heavy-duty, partitioned storage box. Each compartment features a high-contrast size chart on the lid, allowing you to identify M2, M3, and M4 sizes instantly, even in low-light workshop conditions.
  • VERSATILE SCENARIO APPLICATION: Designed for the modern maker. Whether you are building a custom matte-black PC case, maintaining an RC crawler, or fixing household appliances, these black oxide finish screws blend perfectly with dark-colored equipment while providing the structural integrity you trust.
