Elastic stop nuts

Post by Emeraude » Wed Jul 27, 2022 9:33 am

While working on my t over the years where I removed bolts I would replace the nuts with elastic stop nut ( not one subject to rotation). I also spent many years working on aircraft and stop nuts are used almost in all applications.
Would Henry used castle nuts if stop nutswhere available then?

"Would Henry use castle nuts if stop nutswhere available then?"

Maybe only if it was cost effective and/or labor saving?
Wouldn't the labor time spent installing a cotter pin being removed by using a nylon stop nut be appealing to Ford back then...?

My '23 is nut for nut, bolt for bolt as it came from HF. But my '26 speedy has modern hardware. I used nylon stop nuts on body bolts, steering column at the firewall, steering bracket, battery box to name a few. It ended up being a mix of old and new.

I don't use stop nuts (I call them self-locking nuts) on my T, but I do use them extensively on my hot rod. In aircraft applications they should be a one-use item, so over time they are more expensive then reusable castle nuts.
The one exception to the no self-locking nuts in my T is one pivot bolt in the top supports. A lockwasher probably wouldn't work so it appears that a previous owner used a lock nut where (I suspect) a castle nut and cotter pin was originally used.
