5 sided allen?

[Tree-Farmer]

Whats a 5 sided wrench called?

I need a tool that looks like an allen wrench or a hex wrench
Except a hex wrench has 6 sides.

This is for a bolt with a recessed head, like a hex, but 5 sides instead of 6.
The reason for this specialized bolt is for security, its part of a bracket holding in a computer, so it wont get stolen.

Do you know where I could buy a tool like this?

Like a hex key set

or a T-Handle

or a bit set

Working on a Bobcat skid loader? Ran into a 5 sided one for the injection pump/timing if I remember right.

Phill, you are correct. Now I won't say that there are none that are four or six, but I have never seen or heard of any but five sided.

Fire Hydrants use 5 sided nuts. Depending on size, you might want to try a supply house that sells water piping to contractors.

What are you trying to break into ?
Some electrical high voltage disconnects use five sided bolts on the covers .

A 5 sided allen head screws and nuts like on a fire hydrant is called as a Pentalobe .

Check the security bit sets. Those with torx, etc

 

[Greenfrog]

Also, if working on computers, a security set would be useful. Consider those with long shanks.

 

[Greenfrog]

Also, look carefully...there might be a pin sticking up in that screw head, thus the bit will need a hole in the end.
Have you ever seen funny security screws in bathroom stalls? Who would want to take em out anyway?..!! 🥴😏😝
