the rusty screws of the Allen wrench
source:Industry News release time:2021-06-30 Article author:Rosit Popular:Air band saw
The screws of the Allen wrench are very common in our lives. They provide us with great help in fixing objects. But when the screws are rusted and cannot be screwed down, what should I do? Here are some suggestions for you: Shock, knock, burn, rush.
Allen wrench
The rusty screw of the Allen wrench must not be screwed hard with a wrench. It is very likely that the screw will slip, the screw will be broken or the wrench will be broken. In this case, you can tap the handle of the wrench with a hammer to cause vibration. In general, screws that are not severely corroded can be unscrewed by this method.
This is almost the same as making the rusty connection between the screw and the nut detached, and it will be easier to unscrew it when it is loosened.
Some screws of the Allen wrench are very corroded, the previous method is difficult to work, this is the method of fire attack. Use gas welding oxidizing flame to fully grill the screws and nuts, and then drip a trace of oil on the red screws. The purpose of heating the screw is to heat the screw to expand. The purpose of dripping oil is to make the screw shrink quickly when cold, increase the gap between the screw rod and the nut, and the nut can be unscrewed after the oil flows in. However, this method is more limited and cannot be used for flammable items such as plastic parts.
The top of the screws of some components of the Allen wrench are corroded and out of shape, and cannot be unloaded with a wrench or wire cutters. The impact method can be used. First, use a hammer and a flat screwdriver to impact a v-shaped groove in the vertical direction of the top of the screw, and then adjust the angle of the punching cone to impact in the direction in which the screw is unscrewed. After loosening, you can use wire cutters to unscrew the screw. When the "one" or "cross" screw is slippery, this method can also be used, combining with wire cutters to unscrew the screw
