I used the lower end of the range for bolts of that size.  If you need the actual values I can get them from my AME's reference book when I go to the hangar next, probably tomorrow.  Let me know. These are bolts that need to be checked regularly, rather like the bolts for a wooden prop.  The material being clamped is wood and is more compressible than metal and the bolt can become loose leading to cycling of the bolt and probably fatigue.  Worse than that it is a progressive situation as the looser it gets the looser it gets!  If you see what I mean.  The same situation can occur with the main spar bolts.
