Sensenich composite prop three blade - Wire safe

[chiricuca]

I have pruchased th propeller 3F0M7/C68NF-0 and I noted that the bolts have not any hole for wire safe and it catches my attention. Is this normal? How can I assure that it won’t be loose?

Uses Nordlock washers maybe. What is on my Whirlwind GA prop. Look them up. I use on brake calipers too. Safe, save a lot of work

Nord-Lock Washers

Wedge-locking security for bolted joints subjected to extreme vibration and dynamic loads

Thank you so much for the answer. I don't know these washers are so good for this application.

From the attached manual it looks like they should have Nord lock washers.
