Hello,
I need to install some protective bars on my motorbike. They protect the engine / oil carters and things like that when the motorbike fall. I bought them on ebay a long time ago, and never installed them as one of the fixing points is on a threaded rod that attached the engine to the bike frame. When the protective bar's plate is on, there not enough thread anymore to fit the bolt. So I need a longer threaded rod.
I don't know, shame on me what I need to ask for: what is the diameter of a threaded bolt?

I know only the (a) dimension on the diagram, which is 10mm.
Does it mean I need to ask for a 10mm threaded rod or is it more complex than this?
Is there a shop in London, or a good web address where I can buy a good steel grade threaded rods / washers / nuts: I don't want to get it from B&Q basic stuff as it's one of the 3 main fixing points of my engine on the frame (heavy, it's an 1100cc)
The other week someone dropped my motorbike where I work, luckily damage was minimal (as far as I could see) but I may not always be that lucky so want to install these bars now...
Thanks in advance for your precious advises!
Loic
PS - For instance, do you think this is of an acceptable quality?
