580PCS ESSENTIAL 9-SIZE COLLECTION: Never stop a project for a missing part. This kit provides a balanced range of 9 popular sizes: M2(100pcs), M2.5(100pcs), M3(100pcs), M4(100pcs), M5(60pcs), M6(40pcs), M8(50pcs), M10(20pcs), and M12(10pcs). Perfect for precision electronics or heavy machinery repairs. GENUINE 304 STAINLESS STEEL (A2-70): Engineered for longevity in the UK's humid climate. Our washers are crafted from high-grade 304 stainless steel, offering superior corrosion resistance compared to zinc-plated options. They won't rust or seize, making them ideal for both outdoor garden equipment and indoor appliances. LOAD DISTRIBUTION & SURFACE PROTECTION: These plain washers provide a smooth, flat bearing surface to distribute the pressure of nuts and bolts evenly. This prevents pull-through on softer materials and protects your work surface from damage during tightening, ensuring a professional and secure finish. REINFORCED STORAGE BOX WITH LABELS: Say goodbye to messy toolboxes. We use a heavy-duty, compartmentalized case with a secure snap-lock. Each size is clearly labeled with a visual chart, ensuring that small M2/M2.5 washers stay in their dedicated slots even during transport or if the box is dropped. PRECISION METRIC STANDARDS: Strictly manufactured to standard tolerances for a snug fit. Whether you are upgrading your RC car suspension, fixing a 3D printer, or securing household furniture, our gaskets ensure consistent performance and reliability for every bolt and screw.
