【Specifications:】 ● Color: Silver ● Package Quality: 220 PCS ● Sizes: M3 M4 M5 M6 M8 M10 M12 ● Material: High Grade Stainless Steel ● Washer Type: 304 Stainless Steel Large Fender Washer 【How to judge whether it is 304 stainless steel material?】 304 stainless steel is cold-worked and its structure will be transformation, the greater the degree of cold work deformation, the more transformation, the greater the magnetic properties of the steel. On the contrary, the 200-series stainless steel of the second-class quality is likely to be nonmagnetic, so it is a mistake to judge that it is a genuine stainless steel. In particular, the magnetic properties of 304 stainless steel due to the above reasons are not at the same level as the magnetic properties of stainless steel of other materials, which means that the magnetic properties of 304 steel always show weak magnetic properties. This tells us that if the stainless steel strip is weakly magnetic or not magnetic at all, it should be judged as 304; if it is the same as the magnetic steel, it shows strong magnetism, because it is judged not to be 304 material. 【Package Included:】 M3x15x0.8mm ------------------20pcs M4x20x1.2mm ------------------ 20pcs M4x25x1.5mm ------------------ 10pcs M5x20x1.2mm------------------- 20pcs M5x25x1.5mm ------------------ 10pcs M6x20x1.5mm ------------------ 20pcs M6x25x1.5mm ------------------ 15pcs M6x30x1.5mm ------------------ 10pcs M8x20x1.5mm ------------------ 20pcs M8x25x1.5mm ----------------- 10pcs M8x30x1.5mm ----------------- 10pcs M10x20x1.5mm --------------- 20pcs M10x25x1.5mm --------------- 10pcs M10x30x1.5mm --------------- 10pcs M12x24x1.5mm --------------- 15pcs 【Total: 220 PCS, 15 Sizes 304 Stainless Steel Large Fender Washers】
