    Maybe it's one of the variants of the Ultra-Drive Security Machine Screw. Apparently the exact hole design is unique to each customer. Aug 20, 2022 at 12:57

    Reminds me of a phone conversation, back when I used to see things like that on a daily basis…"Guys, you know those fancy new screws you just spent a fortune on? Did you know you can just use a 4mm security hex?" ….Long silence ensued...

    …and another thing - if the steel is brittle enough, you can snap out the security pin ;)) Just bend one way, then back again should be enough. Then a screwdriver or non-security hex will fit.

    Also, once out, replace with screws with a normal (slot, philips, hex or torx) head.

    This is on a playground gate. I'm not going to destructively remove it! I was just curious.

It appears to be one of the variants of the Ultra-Drive Security Machine Screw.

Apparently the exact hole design is unique to each customer, and correlating to your comment that they were found in SW England, made by the U.K. company Fastenright Limited (no connection to me).
