How to take off the rusty screws These tricks will help you get it all done!

　　I believe that many people have encountered situations in their lives when they want to unscrew the screws and found that the screws have rusted, so they can’t be unscrewed. Today, let’s talk to you about how to easily unscrew rusty screws. Let’s take a look!In addition to domestic, wheel nut It has also emerged in the international field and gradually gained the favor of more foreign friends. https://www.hengkefasteners.com/

　　

　　01

　　

　　We can screw the screw with a wrench first, and then hit the handle of the wrench with a hammer, so that after a few knocks, the rusty part inside will become loose because of the knocking, so that it will be much easier to screw it again.

　　

　　02

　　

　　You can also use the method of fire. After fully burning the screws and nuts with gas welding oxidation flame for a while, drop a few drops of oil on the red-hot screws to let the screws cool quickly, which can increase the gap between the screws and nuts and facilitate unscrewing the screws.

　　

　　03

　　

　　If the screw is slippery, we can put a small rubber block on it to increase the friction.

　　

　　04

　　

　　We can also try to use vinegar to remove rusty screws. Sprinkling vinegar on rusty screws can dissolve some rust, and it will be easy to wait for a while before twisting rusty screws.

　　

　　If all the above methods fail, you need to use professional tools.

　　

　　5, with the help of nut breaker. Nut breaker is a special tool for cutting and removing corroded nuts. It consists of a hydraulic cylinder, a cutter and a tool rest. It adopts a single-acting return hydraulic cylinder to cut the nut into two halves at one time without damaging the thread and screw, thus effectively solving the problem of disassembling and replacing the bolt and nut.

　　

　　Specific use method:

　　

　　Open the oil filling plug, fill the manual oil pump box with hydraulic oil, and close the unloading valve;

　　

　　Sleeve the head hole of the breaker into the nut to be broken, and straighten and level it;

　　

　　Press the manual oil pump to push the cleaver higher than the nut. When the AG nut is half of the cleaver, carefully press the manual oil pump to avoid overexertion, and the nut will split at the cleaver speed to damage the bolt thread;

　　

　　When you hear the cracking sound of “beep”, it means that the nut has been broken, that is, stop pressing;

　　

　　Unscrew the unloading valve, return to the original position after cleaving, and remove the cleaver to finish the work.

　　

　　6. Use drip pine. Droplet is a liquid chemical agent, which acts on the contact surface between the screw and the tool to increase the contact friction. After use, the friction force can be increased by 500 times, which is more than enough for general dead screws. If it is used with rust remover and lubricant, the effect will be more obvious.

　　

　　7. Repair artifacts with threads.

　　

　　Take a look at it.

　　

　　Adjust and clamp.

　　

　　One twist, one more turn.

　　

　　Tighten.

　　

　　8. Chamfer the damaged and corroded bolts with the aid of the bolt chamfering tool.

　　

　　Rusty bolts, chamfers and nuts on the site.

　　

　　Chamfering of two bolts with different diameters

　　

　　9. Remove rusty nuts by induction heating. This method is easy to operate, and is suitable for the disassembly or installation of various metal parts, such as driving parts, bearings, bearing seats, gears, bolts, nuts, pipe fittings and small parts. Widely used, suitable for narrow space.

　　

　　And can accurately heat locally, so that the area outside the heated workpiece still maintains the original temperature; However, the heated workpiece expands and loosens, which is convenient for disassembly or installation. Especially for bolts and nuts, it is an ideal solution.
