Do you have a tap? That is the easyist way. Second would be Debonder. If you don't have any, go get some. You will be happy you did for other things like gluing yourself to the counter. Third would be to make a tap out of another bolt. Cut slots in the bolt like a tap and put a point on the tip to help cut into the CA. All else fails, remove the blind nut and heat it with a torch to cook out the CA or just replace it. [8D]
