But nothing ventured nothing gained,
BUGGER but it worked,
It is a very tight fit in the end of the straw which is exactly what I needed,
I recommend the straw be very dry as well as your fingers.
So hex spanner in the head of the bolt then threaded the straw through and past the control rods,
( If you are working in a confined space I recommend a head torch ) and onto the end of the bolt,
I gave the straw a twist and low and behold success.



It only works with nuts 5mm across the flats, which is the norm for M3 bolts and I do use a lot of M3 nuts and bolts in my builds so I hope it helps others when they have tried everything else.
