Can any of you RV builders tell me how I can tighten this nut and bolt?
No wrenches or sockets I have fit. This is built according to the
plans and with the AN nut and bolt called out in the plans.

I sure hope Van gave a little more thought to assembly when
he designed the later airplanes.

Paul, Using a thin socket, you should be able to tighten the nut, except for the interference from the weld buildup on the part.  I would use a longer bolt and put a thicker (or multiple) washer under the nut base to raise in above the weld interference.

No weld there. The bolt is just too close to the tube.
I'll have to check out a snap on tools but I'll just buy
NS nuts and bolts first.
