I was just rummaging through some tools and hardware someone gave me recently and found a box of slotted nuts which I couldn't identify. After examining them for a few minutes, I still couldn't figure out what the slots were for. I wondered if there was some kind of spline tool that would tighten them if they were recessed, but then why bother with the flat sides? Anyhow, I decided to look them up and learned that I have what are called castellated nuts (not like an AR15 castle nut).
They looked like this: 
Apparently, they're pretty good at holding things together when used in conjunction with cotter pins and the like. This article I came across shed some light on myths about Fastenating article about nuts and bolts |

Don't you Castle Nut, bro?
Used along with a hole in the bolt and a cotter pin to keep it from vibratung off. |

I think you misspelled 'fascinate'.
You did ,however,inadvertently remind me of a "little Johnny" joke.......... The teacher asked little Johnny to use ' fascinate' in a sentence....Johnny thought and thought and finally said very proudly "My sister's sweater has10 buttons.....but her tits are so big she can only fasten eight" |

Good on searching out personal knowledge. There are soooo many types of fasteners and methods out there and some can get real interesting.
One of my personally favorite methods of using a nut and bolt is bolt tensioning... You put the bolt through and then a machine stretches it and you hand tighten the nut. when the machine lets go... boom, it aint going nowhere. It is used for larger bolts where getting the proper torque needed is not feasible using a standard tightening method.  SKF Hydraulic Bolt Tensioner HTA.wmv |

I found out about castle nuts around the mid-2000's when I replaced a tie rod on a Honda Civic. Also found out how to use a tie rod separator tool at the same time.
I used a ball joint tool to pop it out.

Bellvilles are neat! you can stack them face to face and get more movement with the same spring force. Or you can stack them parallel and get the same movement with greater force. Or mix and match.
Not sure they'd be good in a can though because once they got hot they'd soften and lose tension. |

Quote HistoryQuoted:
Don't you Castle Nut, bro? Used along with a hole in the bolt and a cotter pin to keep it from vibratung off. The cotter pin is there most of the time as a safety feature more than anything (or safety wire in some applications). You still need to properly torque the nut to being with to have the proper preload in the joint. And if you do that right the nut shouldn't back off. Just putting the nut on loosely and then slamming home a cotter pin will usually result in bad things happening. That is why ball joints and tie rods have the hole in the threads drilled so that the only way to get the pin in place is if the nut is tight enough. But as you said, vibration and rotation of the joint itself can cause it to want to lose tension, and the pin is there to help keep it from working itself even more loose to the point of coming off all together. Yes, there are some light use cases where the cotter pin really does help hold the nut on, but those are usually in things like lawn and garden equipment, etc. Heck, some things now don't even use the nut. They just use a big flat washer and a large cotter pin through the shaft to hold things in place. That's a cheap way out of using a circlip... Sorry, can't help myself. I deal with some goofy stuff at work and sometimes people think things like keys and keyways, or things like cotter pins are the main way to transmit load in a bolted joint, when really they are primarily for alignment, and have a secondary use to help carry load if something else goes wrong. |
