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,

What size is the bolt? Somehow I was getting the extra keyboard
features
symbols instead of /?. I think i have it now. Cheryl is at the
distibution
center and can get you in touch with a franchizee. You can then
phone them
to meet if you need to get special tool

It looks to me like an offset or angle wrench would work fine. Other
suppliers make them also. A crowsfoot socket would also work if
torqueing is
required.

1/4 28.

Not enough clearance for a box end wrench. Even Snap ON.
Perhaps a Snap On socket but I have not tried it yet.
I kind of doubt even a snap on socket would fit.

The answer is an NS 12 point bolt and nut.

Paul,


You could take a deep socket that would otherwise fit the bolt, and
then grind away a wide 'slot' near the opening, enough to allow the
socket to fit onto the nut and also allow turning.  Then you could
simply use a ratchet handle to turn it.  The socket might not spring
open too much and allow you to tighten the nut.  You wouldn't need
a thin walled socket either...you could use a very thick walled socket
which would resist springing open since the opening would allow
placing the socket in place.  Yes, you would have to remove the
socket and replace it with each turn...perhaps just use this method
for final tightening.
