I’m after a fine thread m20 bolt (to remove the rotor off of the sv), does anyone have one I can borrow, or know of a shop that stocks them please?
No, but National Treasure will probably be along in a minute to tell you that you should already have some in stock 
Screwfix sell M20 bolts so do B&Q
I bought some from screw fix, that’s how I know I need fine thread (though now have a bag of 25 M20 bolts with course threads)
M20 fine, I’m assuming that’ll be a 1.5 pitch? A fairly tall order, 1.5 pitch bolts tend to become as rare as hens teeth over M16.
Got any breakers near you?
You’ll be looking for a sump plug or an HGV engine cylinder bolt.
Try Sealey Ms034 Motorcycle Flywheel Puller from halfords
Or machine mart do a laser version for £18
Not checked to see if it has m20 though …

Cheers guys, found two now, one in Slough and one in grays, oh the places I get to go…
Clarkenwell don’t go that big on fine thread, and it looks as those sets don’t include m20.
