Or more specifically, Pin spanner nuts.

I feared that level of specificity might overburden the OP.

We've successfully conquered the "nut" stage, now one step at a time.

Thanks Bill, nice to know I'm not alone

its technical term is a wotnot, sometimes a thingy, dodah or wigit.
spose if you use a pin spanner to open it it must be a pin nut, though the bycycling fraternity over ere call it a peg spanner i'm told so maybee bycyclers have peg nuts? [hard saddle i suppose]
what about the ones with notches, i use a hook spanner on them?
its a dodah

For some reason the term "New Departure nut" surfaced in my memory.

Did anyone else have this thought?

castellated nut?

Nice to see a bunch of nuts trying to describe a nut

If it holds the prop on to the prop shaft of a ship and is mounted with the aid of a hydraulic pump, it's usually a Pilgrim nut

Capstan nut.

Roar! Brilliant!

castellated nut?

That's what I have been calling it, but aren't they the type that takes a split-pin?

I call it a nut.

Succinct and to the point

Thanks Bill, nice to know I'm not alone

It comes to us all in the end!

peg nuts?

Doesn't that happen when the chain snaps, or is that called bar-nuts?

Capstan nut

I think we have a winner

Since you all found that amusing, I thought I'd confess this little story...

The attached picture shows a reconstruction of the offending capstan nut.

The nut holds the spindle in the quill of my Haighton mill. The nut is locked in place by a set screw (with a nice brass thread protector).

Having undone the set screw I set to locating the pin-spanner that I knew I had somewhere - The better part of an hour later I found the said spanner only to find it was 'the next size up' , too big.

Plan 'B' involved a pin inserted in one hole so i could attack it with my ER32 collet chuck C-spanner - After about 15 mins searching for an appropriate size rod, I'd found a 4" lenght of chromed steel from an old printer.

I popped it into the hole nearest me to check the depth where upon, under just the weight on the rod, the nut spun undone :

I have heard Bell Nut

[David Utidjian]

The nut that holds the main rotor on a helicopter is called a jesus nut.

I usually call the type that have holes oriented radially "ring-nuts", the ones with holes axially "spanner-nuts".

I think I like "capstan nuts" also... most descriptive. Unless, of course, one has no idea what a capstan might be.

This time of year a particularly hard nut is seen in abundance under certain trees with shaggy bark- it is called a Hickory Nut
