Cam Lock Bolt - What is type tool is needed?

[BC_Explorer]

The bolts that hold the cam lock hinge on my trailer is loose. What is the name of the tool (screwdriver of some sort) is this? I know it is not a torx head but I cannot find a reference to the proper name so that I can purchase the tool.

Thanks in advance.

Tamper resistant torx. It's nothing more than a hollow torx bit. Really easy to find but use a small ratchet style, not screw driver style for that. Won't get it tight enough to stay. I would look at what it's tightened to as well.

@Tigris99.

Thanks for the help. I'll pickup those torx bits at Home Depot tomorrow. Hopefully I can tighten enough for now as I am leaving for 2 weeks vacation on Wednesday and don't have a lot of time to be taking out a wall to get at the bolt or whatever it threads into.

Sometimes they are called security Bristol bits or Polydrive bits. But tamper proof torx seems right. I have a set of 1/4" and 3/8" drive bits, but they are not security, no hole. Let us know if HD has them, I'll need one for the ramp.
Thanks,

Is that the nut maybe? I've seen those on carriage bolts.

If it's the same as mine it's a T45 tamper proof torx. In HD you find them in the socket section for a couple of bucks. It's like a lag screw with a torx head.
