Sorry, I don't have a picture of the prop bolt nuts on the Hartzell. At the time, I did not realize those nuts are supposed to be safetied and only did that after finding out. I do remember they were a major pain to access and I wired them in pairs. Here is a view of the front of the Hartzell prop where access is far easier. Even so, with little talent for deftly manipulating safety wire pliers like the pros do, using .40, this is the result of my effort after at least six failed attempts.

Default C/S prop

I'll be impressed with anyone who can finish a C/S prop mounting bolt safety wiring session and use only three pieces of wire! I usually have a fairly large pile of scrap wire chunks by the time I'm done. I use .032 for the prop.

Those look really easy! I want to see someone do a Constant Speed McCauley hub prop - With .041 wire!

+1. Craig Catto has a good write up on this. He suggests very tight safety wire on his props (tight like guitar strings - he even suggests twanging them and listening) It only takes a few degrees of loosening to allow fretting between the prop and hub, which produce high heat and very fast wear. For most uses of safety wire, those would be fine, but not for the prop bolts on an FP.

people do tend to over twist safety wire. max on .032 to .041 is 12 twists per inch.

My suggestion or at least what I did that I think worked out well for the man prop bolt as they are harder to reach. Torque all the bolts to the spec and check to see which pairs line up well for the safety wire, mark them. Then you can start the wiring if they are lining up well or at least those that do line up. Then you can back out those that don't just to get the wire thru the hole and then re-torque to the specified value.
