I ordered these security bits to open my 2018 Mac Mini and install new memory. They are exactly what I need for that. There is a wide range of torx wrench sizes available, including ones that will fit the above computer. While I can't speak to their durability over a long period of time (I've only had them a month), the bits I've used have withstood the screws in a Mac Mini. Now they have a permanent home in my tool box. The size (thickness) of the bit base (e.g. 10x faster!) is standard so they will fit any number of interchangeable bit screwdrivers. I have a small rechargeable screwdriver that they fit in, but I do NOT recommend using a powered device to unscrew/unscrew computer hardware (I haven't). I only mention this because your needs may not be computer related and using a low power screwdriver with these bits would be a good option. Conclusion: I am very satisfied with these security bits. Standard size and wide range of sizes make them a great addition to any toolbox.
