I just did this last week, be advised it may be helpful to pre thread the safety wire into the nut, before you get to final torque------I even had to back off a couple of nuts, insert the wire, and re torque them, just no other way to get the wire in place.
Good luck.
So I'd guess the other 99% of the population uses a socket and standard torque wrench, so pre-threading the wire isn't an option, right?
Since the bolts are safety'd in pairs, I'm not sure I see why they become hard to wire?....
thx
We also have to do it in the next few days on the RV10. Two questions-
Will a standard torque wrench with a crow foot attached work? The crow foot looks like the bottom item of Mike's post but with the square hole to fit onto the torque wrench.
What is the torque value specified? The prop manual is in the hangar and I do not know if it is in there so I am asking.

Safe wiring Hartzells always seems nonsensical. The prop can't fall off the airplane unless all six bolts back out simultaneously; surely you'll notice a problem before then! No safe wire will keep an individual bolt properly torqued if it decides to loosen for some really weird reason. Yet we all safe wire because the facility is built into the bolt.
Hartzell does say .032 in an FAA-approved manual. Yet the local FSDO wants .040 when a DAR (now retired) I always used didn't give a Rhett Butler. I'd use .032 if whoever you will use for an A/W inspection will buy it. It's easier to install and - see above - is inconsequential.
