I have several ARFs that use Metric #6 bolts about 1 1/2" long to hold the wing to the body of the plane. Although I try to keep track of these bolts they seem to get lost often. I would like to buy a dozen or so of these bolts to replace ones currently missing and to have some extras, but I can't seem to find a good source. The local hardware stores that carry metric bolts only have short bolts less than 1" and the ARF companys want $4 to $5 plus shipping for two bolts. The outfit that advertises cheap fasteners here on RC Universe doesn't seem to carry them. Anybody have a good, cheap source for these bolts?
