People can get through those things with small amounts of metal like the buttons on their jeans. So how big does the metal object have to be for it to set the beeping thing off? The one you walk through.
Could it detect a safety pin or those clips from a tensor bandage thing?
@Kurt because I’m going on a plane tomorrow and those things are part of my normal attire. I would like to avoid any potentially awkward situations that may arise with airport security, if you must know.
It depends entirely on how sensitive the detector is, or what level they have set it to if it is adjustable. All airports will not be exactly the same.
In the past, I have seen them detect the foil wrappings around the gum in a package (when they used to do that with gum). But it does not go off for eyeglasses (metal frames), wedding rings and so on.
I would not worry about buttons – like the metal clasps on suit pants, or the metal button on a pair of jeans. The clips on ace bandages (same as tensor bandage??) are probably aluminum, so they would not likely be detected anyway.
In any case – if it goes off, and your pockets are empty already, then they will go over you with the hand held wand to find the specific place that causes the alarm, and inspect it. If it is something removable – like a safety pin, they may have you take it off, then go back through the detector.
It may add a bit more time to your experience, but it is not any kind of a problem. Those kinds of things happen often.
Why do you want to know?

Well, actually people don’t get through with small amounts of metal like the buttons – the buttons will set off the metal detector and then they do a personal scan to verify it is the buttons. Anything as small as 1/4" will register on a metal detector. And a safety pin will be detected.

Normal metals that go on your dress will not alarm. Some times, watches or belts will alarm. Gold will not alarm in most of the airports. But in some airports, where the detector sensitivity is very high, even a ring will alarm and you will have to remove everything possible.
Nothing to worry when you are harmless.
