Many people say that these two are actually similar, but we must know that the demand for each product is different, so we have to choose according to the needs of the product, but before we make the choice, It is necessary to know where the difference between the two screws is. What are the advantages of the two?
Stainless steel screws, whether they are 304 stainless steel, 316 stainless steel, or 302 stainless steel screws, are difficult to distinguish with the naked eye because the surface color of stainless steel screws is almost the same. It can't be distinguished. Some people say that the difference between stainless steel and carbon steel can be distinguished by magnets. This is also unreliable. The performance of stainless steel screws will change after production. The original non-magnetic stainless steel wire is produced. The screw will be magnetic after the out, and this is unavoidable in production.
   Therefore, we can't distinguish whether it is a stainless steel screw with the naked eye or a simple magnet tool. When buying stainless steel screws, we must choose the screw manufacturers with the strength and integrity to purchase. If necessary, you can use the test report of the screw wire to the manufacturer.
