Several solutions for rusting stainless steel hinge screws

Five parts manufacturers tell you how tosolve the problem ofstainless steel hinge screw rust

1. Knocking: Use the edge of the square top hammer to strike the rusted stainless steel nut, which is very simple to loosen the nut. For example, the nut of the fixing bolt at both ends of the pedal of the bicycle can be tapped according to the thickness of the pedal, the metal structure, and the force of the hammer. The nut at the cast iron can be used slightly more, and the plastic should be hit quietly. If it is still not possible, the nut can be easily removed by hitting the nut with a hammer in the direction of the circle.

2, burning: Some screws embroidered very serious, with the above methods still not effective, you can use "fire attack." Use a gas welding oxidizing flame to fully screw the nuts and nuts, and then apply a trace of oil to the red-hot screws. The purpose of the heating screw is to swell the screw. The intention of dripping oil is to shorten the screw quickly and shorten the gap between the screw and the stainless steel nut. When the oil flows in, the nut can be unscrewed. However, if there is plastic equipment nearby, use this method with caution.

3. Welding: When the equipment is disassembled, the situation of twisting the screws is endless. For broken screws, spring hinges, generally do not use electric drills, because the wire holes will be drilled if you are not careful. A better method is to weld a long piece of iron on the broken wire. The cross section of the iron block is determined by the diameter of the stainless steel screw.

4. Shock: For rusted screws, do not use a wrench to harden them to prevent the six corners of the screws from being screwed, twist the screws or screw the wrench. At this moment, the handle of the wrench can be quietly shaken with a hammer, and the screws that are generally rusted can be shaken and unscrewed.

5, rush: some equipment stainless steel screw top corrosion shape, can not be used wrenches, wire cutters to unload, both shock method. First, use a hammer and a flat-top screwdriver to impact a v-groove in the straight direction of the top of the screw. Then, adjust the angle of the cone and impact it in the direction in which the screw is screwed out. After loosening, the screw can be screwed out with a wire cutter. This method can also be used when the "one" or "ten" screw is slid, and the screw is screwed out together with the wire cutter.
