Airport security is trained to recognize a wide variety of items, including metal objects. If a metal butt plug is detected during a security screening, it is likely that security personnel would recognize it as a harmless personal item and allow the traveler to proceed. However, it's always a good idea to check the specific regulations and guidelines of the airport and airline to ensure smooth passage through security. **

To drill a hole in metal, you will need a drill press or a handheld drill with a metal drill bit. Start by marking the spot where you want to drill the hole with a center punch to create a small indentation for the drill bit to grip. Secure the metal piece firmly in place using clamps or a vise to prevent it from moving during drilling. Then, slowly start drilling at a low speed, applying steady pressure and using cutting fluid to lubricate the drill bit and prevent overheating. Make sure to wear safety goggles and gloves while drilling to protect yourself from metal shavings. **

To measure a hole in metal, you can use a caliper or a micrometer. First, place the caliper or micrometer across the diameter of the hole and tighten the jaws until they make contact with the edges of the hole. Then, read the measurement displayed on the tool. This will give you the accurate diameter of the hole in the metal. Alternatively, you can also use a hole gauge, which is a specialized tool designed specifically for measuring the diameter of holes. **

One way to secure a metal pin in a hole is by using a locking mechanism such as a cotter pin or a split pin. These pins have a looped end that can be bent back once inserted into the hole, preventing the pin from sliding out. Another method is to use a retaining ring or a circlip, which fits into a groove around the hole to keep the pin in place. Additionally, using adhesive or epoxy can also help secure the metal pin in the hole by creating a strong bond between the pin and the surrounding material. **
