Help me identify the screw type

[MUJI]

I was trying to open up my MF A3 amp this afternoon hoping to take some pictures and found this unique screw that I could neither unscrew with allen key, phillips or slot type. Would you be able to help me with identifying it? This is so I can find the right screwdriver for it.

Picture link provided. Many thanks.

That is a Torx type security screw, you can buy security bit kits for a few quid online.

Looks like a torx security to me. No idea of size but I suspect the same as most kit uses which I took a note of at some point and will see if I can find

As others have stated above it is a Torx (probably T10 size) but has the security pin in the middle. When I needed this type of Torx driver myself I had trouble getting one at the time and 'cheated' by cracking off the pin and using a standard Torx.......worked fine but a bit drastic perhaps!

Thank you Honeywell, JP, Chris and Dave. Learn something new everyday when I bother to flip the amp around.

Thinking about using the MF A3 as a project of getting into mod. Will take some pictures to share it in this forum and hopefully get some advise along the way.

Thanks guys.
