Not sure I follow? My only point is that safety wired castle nuts are about the best way you can go for securing fasteners. It's aviation standard but absolute overkill for most applications. Nylocs suffice for 95% of applications and distorted thread is good enough for 95% of the remainder.Who here is using Castle nuts with safety wire? I'd guess .001 of the people reading this thread. All my nylon cap nuts are grade 5 or 8. Is that what you mean by cheap?
For the nylocs I'm just saying they're too cheap to risk using one twice after the nylon insert has been deformed. I can't remember the exact number but their holding power is significantly reduced on a second usage. McMaster has grade 5 1\4-20 nylocs for like $5-$6 per hundred last I bought any....
