Comprehensive Nuts and Bolts Assortment - 840 Pieces
This extensive fastener collection provides everything needed for precision mechanical work, electronics assembly, and general repair tasks. The set contains 840 carefully selected pieces across three essential metric sizes: M2, M2.5, and M3.
Construction and Materials Each fastener is manufactured from high-quality carbon steel with a protective zinc finish, delivering excellent corrosion resistance and long-lasting durability. The hex socket button head cap screws feature uniform threading with a smooth, precise pitch for reliable engagement and consistent performance.
Design Features The round head design provides an enlarged contact surface area, ensuring superior connection reliability compared to standard screw heads. Each screw utilizes a hexagonal socket drive system that requires Allen keys for installation, offering excellent torque transfer and a clean, professional appearance when fastened flush.
