Can’t figure out the screw bit needed for this and that’s after going through my bits in my pro tech tool kit.

That looks like a Torx TR6, TR8 or TR10 screw. There are two versions of Torx these with a pin in the middle is the security version (TR) By chance is this a five lobe screw? Your image is not very clear, then that would be a 5-Point Tamper Resistant Star Bit

Hi @danj , Here’s a better view of it to confirm
