we have a £15 screwdriver and bit set that we keep in the house and even those cheapos came with the 5 lobe security screw bits.
Have you counted the lobes? Usually, they come with 6-lobe screw bits, not 5-lobe.

Alternatives include snake eye screws.

I know firsthand that you can’t unscrew clutch head screws. So while I wouldn’t use them for a bottle cage, I have used 1-way screws in other applications.
