I was removing an old satellite dish off the shop and thought I had the correct tools in hand, a socket and an adjustable prototool's adjustable wrench.
Up the 12' step ladder and discovered none of the tools I had with me would work.
Has anyone ran into this nut before?
I have never see one, it is most likely a "security" nut.
Yeah once or twice. here's the proper tool for it.
Yes it is called a penta nut . A 16 point socket does not fit also .. Vice Grips for the win .
Also handy for oddball "non=Penn" handle screws...

They're a security nut for lineman purposes. There's a special T socket wrench made to fit them. The concept is not unlike special keyed nuts used on mag wheels.
Padmount transformers have them on the door bolts to keep regular folks out of the electrical connections. There are penta sockets for them too.
