What torque are you setting your AN 5 wing nuts at.
The Torque tables on the net say 60 to 85 ft lbs for shear nuts
and 100 to 140 ft lbs for tension nuts. I was putting the final torque
on them yesterday and they are at 40 ft lbs now and seem very
tight. Are we in shear or tension? I thought i would check rather than
screw up at this stage of the game.
Thanks

HI Mike,
I think you have confused foot-pounds with inch-pounds. That would
make a 12 to 1 difference. I think the proper torque for AN-5 bolts
is around 100 to 140 inch-pounds.

Hello,
Does anyone know the position of extrusion 6V11-5 in relation to the spar?
My plans do not show it (and, of course, ZAC is closed today)...
Thanks
Carlos

Carlos:
My drawings show the forward end of 6-V11-5 to be 45mm ahead of the
front surface of the spar web. I can't remember how I measured that
distance with the lower skin in place.

Hi Paul
Thanks for your response. But I double checked
the AN Bolt Torque chart and I still come up with
60 to 85 Ft. Lbs. for AN 5 Nuts in shear and 100 to 140
Ft. Lbs In tension. It doesn't make any sense to me
either. It seems way to tight. Where are our engineers.
Regards
Mike Lord

Michael,
Check you Zenith construction standards CS #407.
100-140 for the AN365 nuts and 60-85 for the AN316 nuts for AN5 bolts.
Both are inch-pounds

Ref AC43.13-1B "Acceptable Methods, Techniques, and Practices AIRCRAFT
INSPECTION, REPAIR & ALTERATIONS".,
PAGE 7-9
Table 7-1 "Recommended torque values (inch-pounds)"
FOR 5/16-24 BOLT
100-140 WITH TENSION TYPE NUTS
AND 60-80 WITH SHEAR TYPE NUTS.
Again, see that the values are in inch-pounds.
