Stainless steel screws are widely used in life, its role is mainly to connect the two workpieces together, to play a fastening role. As the screws are exposed to the air for a long time, very easy to rust, it is not easy to unscrew, the following Aozhan hardware fastener factory to explain to you a few methods, so you can easily screw down.
A.shock: we can first shake the rusty screws, can not directly use the wrench to screw. Because the product material and screws rusted inside, very solid, so the rusted screws with a lot of force can not be unscrewed. If the screw is tightened with force, it is likely to damage the screw rolling teeth or cross groove. Assuming that it is an Allen bolt, it may cause damage to the Allen bolt. We can use a shake, you can shake off some rust, the important part has been rusted out, so it will be easy to unscrew.
B.Tap:Rusty stainless steel nuts are very easy to loosen when tapped with a square hammer. For example, the nut that fixes the bolt on both sides of the bicycle pedal, depending on the thickness of the pedal and the difference in metal components, can suffer more or less impactful. The nuts of pig iron can be properly knocked with gas, plastic should be lightly knocked. If this still can not be unscrewed, we can use the hammer head to smash the nut in the direction of the screw teeth, one circle after another.
C.Hot: We can choose to “fire point attack”, with a gas oxidation fire baked screws and nuts, after the blazing screw smeared with a drop of oil. The purpose of heating the screw is to make the screw in the heating pent up. The effect of the drop of oil is to make the screw shorten rapidly when it is cooled and to raise the interval between the screw and the nut. When the oil is injected, it will be easy to unscrew the nut. This method should be used with caution if plastic equipment is around.
D.Welding: There are various cases of broken screws when equipment is disassembled. For broken top screws, we can’t use electric drill because we will drill wire holes if we are not careful. A better solution is to weld a long iron to the broken wire. The cross section of the iron is determined by the diameter of the stainless steel screw, which makes it easier to unscrew the screw.
The above is the method of unscrewing rusty stainless steel screws, if you have a better way, welcome to discuss together.
