I have a Global Freestyle that lost one of its wing bolts sometime during its last flight. Luckily, the wing did not come off and the plane is OK. However, the wing bolts are metric 4mm x 40 mm. I have looked at all of the local hobby stores and at all of the online stores, and no one has 4 mm x 40 mm bolts. Does anyone know if there is a standard size bolt that would fit using the same blind nut that is already in the plane? Thanks.
