My friend has a RV7 and is looking for torque values for the AN7 and AN 4 attachment bolts that run through the fwd spar. Having trouble finding torque values.
Thanks

Torque values for AN bolts can be found in AC43-13 Page 7-9, Table 7-1.
Those two other holes get bolts. See Van's Service Bulletin SB12-08-14.

Those holes aren’t for the shear bars bolts, 704G.
Torq- AN 7- 450-500inlbs
AN4- 50-70inlbs

Guys- I'm thinking that there may be some confusion regarding the holes in the fwd spar web.
RV7 Drawing 11 appears shows that the AN4-13A bolts don't go thru the whole assembly. There are nut plates on the fwd face of the wing spar for those bolts to screw into.
If you look at that drawing approx zone 10C at the F-704C-L it looks like those holes are empty.
Am I missing something here?

You're correct. That is how mine is done. The block, 13A bolts and nut platenuts are installed and the bolts do not carry all the way thru the spar. I too have the holes open in the front spar web. (Pic#1 is rear view, Pic #2 is the front).
