Dear All,

This is a bit silly, but I can search for it and install it only if I know what it is called: I just received a US40+ kit a close friend built for me. However, he built it such that the nylon bolts that hold the wing to the fuse screw direct into some wood instead of putting in a nylon bolt nut (See picture). In many of my ARFs, the same arrangement has either a SCHS nut in the fuse side or a nylon nut there. I am worried that after assembling and dis-assembling the plane a few times, the screw will shear straight out of the wood and I will have a crash. So please tell me what the nylon nut is called
