Hi Guys,

I just recently aquired an Extra and am wondering about the wing bolts. They appear to be 10-32 but the nylon bolts can't be tightened without appearing to be stripped. A metal bolt works fine. Considering this is one place where a single point failure can cause the loss of the aircraft, I'm considering just using a rock solid metal bolt. Is there any good reason not to use metal and have others had the same problem with a nylon bolt threading into a T nut ?
