Stainless steel micro screw is used very frequently in everyday life. But after long time, it is also easy to rust. So how to loosen the stainless steel micro screw is a big problem. I will teach you five tips to solve the rusty micro screw in further detail below.

   1.Shock. For the rusty micro screw, it can not be hard twist with a wrench, to prevent sliding screw the six sides edges, twist screws or twist the bad wrench. At this time, you can use a hammer shock wrench handle gently. Generally, the rusty screws can be screwed out under the vibration.

   2.Knock. Use your hammer edge to knock on the rusty stainless steel nut. It is easy to make the nut loose.

   3.Burn. Some screws are corroded seriously, and the above methods are still not working. You can adopt the method of “fire attack”. Use gas welding oxidizing flame to barbecue the screw and nut fully. And then drop a little oil on the burned screw.  The purpose of heating screw is to make the screw heat expansion. The aim of drip is to make the screw cooled rapidly shrinking to increase the gap between micro screw and stainless steel nuts. After oil flowing into, the nut will be easily unscrewed. But if you have any plastic components nearby, you should be cautious to use this method.

   4.Punching. The top of the rusty micro screw of some device are corroded and contorted, they can't use a wrench and cutting pliers to discharge.

   5.Weld. For the broken top screw, it generally does not use electric drill. The better way is to weld a long iron on the broken wires.
