Machine Screws, Nuts and Washers, 1080-Piece M3-M6 Zinc-Plated Carbon Steel Assortment - wugongshan

Machine screws, nuts and flat washers in a broad metric assortment keep repair and assembly hardware organized for furniture, vehicles, electronics, machinery and 3D-printing projects. This wugongshan set contains 1,080 silver zinc-plated carbon-steel pieces covering M3, M4, M5 and M6 threads. Cross-slotted pan heads offer a familiar drive, while separate case compartments help replace missing fasteners without sorting a loose mixed box.

The documented model C lists sixteen screw types, although only fifteen diameter-and-length combinations are enumerated: M3 at 6, 10, 14 and 20mm; M4 at 10, 20, 25 and 30mm; M5 at 20, 30 and 40mm; and M6 at 10, 20, 30 and 40mm. It also includes four nut groups and four washer groups. Treat the screw-type count as a source conflict and verify the current compartment chart; models B and E may differ.
