Can't seem to find a reference for the size of this bit. Thanks for your help.

If you follow the factory procedure to replace the schnorr washers EVERY TIME you remove the bolts, and properly torque them, you will never have an issue with them backing out. The safety wire is a fix for the problem of "not following the directions".

Id also add that from my experience most people don’t know what they’re doing when safety wiring.

I have a bag of 100 Schnorr washers. Send me a PM and I’ll throw some in an envelope for you. The ridges of the Schnorr washers lock the bolt in place. But you crush those ridges in the process of torquing the bolt. So, it’s a one time use only washer. Since people don’t follow the directions and change them after each use, they get to a point when the washer won’t hold the bolt and it keeps backing out. So they spend time and money on the safety wire solution. Safety wire isn’t meant to keep the bolt torqued, it’s there to stop a catastrophic failure if the bolt does come loose.
