Stainless steel screws are used frequently every day, but they are rusted for a long time. If rusted, how to loosen the stainless steel screws. Use the following to solve:
1 Earthquake: Regarding rusted screws, do not use wrenches to tighten them, so as to prevent the six sides of the slide screws from twisting, or to loosen or loosen the wrench. At this moment, you can use the hammer to slam the handle of the wrench. Usually, the rusted screws can smash down.
2 Knock: Use the edge of the square top hammer and tap the rusted stainless steel nut. It is easy to loosen the nut. For example, the nuts of the fixing bolts on both ends of the pedals of the bicycle can be tapped on the nuts according to the thickness of the pedals, the metal structure, and the grasping force. The nut at the cast iron is slightly more powerful, and the plastic must strike it quietly. If it is still not possible, use a hammer to turn the nut in the direction of rotation to easily disassemble the nut.
3 Burning: Some screws are very badly embroidered. If the above method is still not effective, you can use “Fire Attack”. Use gas welding to oxidize the flame to screw the nuts and nuts, and then apply a small amount of oil to the red-hot screws. The purpose of the heating screw is to cause the screw to swell. The purpose of the oil drop is to make the screw cool and shrink quickly, increase the gap between the screw and the stainless steel nut, and the oil can be unscrewed after the oil flows into the nut. However, if there is a nearby plastic device, use this method with caution.
4 Chong: The stainless steel screws on some equipment are corroded at the top and cannot be removed by wrenches or wire cutters. First strike a v-shaped groove straight in the direction of the top of the screw with a hammer and a flat top screwdriver. Then, adjust the point of view of the punch cone and hit it in the direction of the screw. After loosening, use the wire cutters to unscrew the screws. When the “1” or “10” screw is sliding, this method can also be used to connect the wire cutters to screw out the screws.
5 welding: When you open the equipment, the status of the screw is endless. For broken screws, electric drills are generally not used, and holes will be drilled due to slight carelessness. It is better to weld a long iron block on the broken wire by electric welding. The cross section of the iron block is indeed made of stainless steel screw diameter.
