I don't think its a tamper proof screw, why would a trailer manufacture bother? That costs extra bucks.bet it's anti tamper screws
had a 50+ pc set of bits in the lab.
lots of korean/taiwan equipment had them


That would be Torx drive. Polydrive/Ribe is different- subtle, but different enough that they won't interchange.Those have been out for years. I've seen those star screws used on few things over the years. You can buy the bits for them practically anywhere.

Looks like a variant of polydrive.

Similar, but different.
