hello everyone i would like to show how to crew and unscrew screws like this many times in plastic without damaging the thread when you try to tighten up the screw in plastic or aluminum or some soft metals like this and tied it without keeping any rules next until it if you need to disassemble it again and tidy it again if you untied it and tell it if you just do this few times and at one point you just cannot tighten anymore it's just spinning infinitely why this is happening and how to avoid that i will show now to illustrate what's happening with thread i've just used a plastic pipe and i screw this big screw in one of the site in the same way like similar screws are going into the plastic pillars this is how the thread looks like after the first cycle and it obviously looks good next i screwed it again by aiming the thread which basically is pushing the screw gently into the hole b
