ego - tapping screws , also squall flat solid metallic element screw , are very various . They can be used to firmly tighten metal together , including aluminum . They can also be used to efficiently fasten metal to other materials , such as Grant Wood or charge plate , by creating a much stronger bond than a regular nail .
Aluminumhas many characteristics that make it easy to work with . It ’s lightweight and easy to shape . However , aluminum is also bed to resonate , and when used as building material for boat , for example , this can be a job when the engines cause the frame of the gravy boat to vibrate . Regular shtup and nail have a tendency to come loose under vibrations , so they are not good fixing for aluminum . Trilobular untarnished brand self - tap screws , on the other hand , are ideal . Self - exploit screws are likedrill bits ; they have a needlelike tip like a cutting blade and a thread that go all the way down the duration of the screw . They are designed to keep flimsy metal from denting .
To expend self - tapping gaoler , you may demand to practice a cowcatcher hole first and then place the screw straightaway on the atomic number 13 sheet . Stabilize the screw so it does n’t tilt as it goes in and twist the screw into the metal . Let it turn until it perish all the way through , as the threads and the acute point make their own hole . Be careful not to overtighten the screw since the alloy can be damage or the screw can break .
The reward of using ego - tapping screws for aluminium is that they are easily remove without damaging the metal . They can also be reuse in the same stuff .
