No4 butt srew seized! Tool help...

[Scout Sniper]

Thats a great amount of information, thank you.

Was thinking as i cant find a screwdriver nice and wide i might precisely gring up a cold chisel to fit as the body will also fit in a socket!

Looking at the picture of the bolt head, my only saving grace is the head depth is actually quite shallow so really is a fairly small section being gripped by the wood.
