Taipan Veteran Help

Hi all,

Recently got a Taipan Veteran, which I absolutely love, but it decided to stop cocking yesterday.

I opened up the trigger/firing assembly and played with some of the set screws to get it sorted out. I believe it's the shear tensioner set screw thats the source of my issues. Unfortunately, I stripped that set screw when trying to loosen it with a 5/64 hex key.

I will now be attempting to "easy out" that set screw. Does anyone know what the thread pitch, length, hex head or any other relevant details on that set screw is?
