Hey guys, got meself some of these pro-bolts put first in frame no problems, second one half may in and the head snapped off, took the bolt bit out with pliers. put another one in thinking maybe it was a dodgy bolt and this one snapped off in the frame. So I had to drill my mount and tap it to m6. So im an unhappy chap lol I used copper greese on the bolts after finding the first one tight. and I don't understand why they snaped so easily and if they are so weak why make them. Thanks Adam
