I am not sure what the standard name for this fixing is now. I guess we could give it an international standard via homemadetools. Any ideas please post (funnier the better)

Hi All
This post via Wikipedia explains all about different types of keys:
https://en.wikipedia.org/wiki/Key_(engineering)
I also saw this on the web:Dutch Pins: How To? - Page 3
So it appears they are both correct. You never stop learning!Quote:
A "Scotch key" or "Dutch key" also provides a keyway not by milling but by drilling axially into the part and the shaft, so that a round key can be used. If the key is tapered, it is referred to as a "Dutch pin" and is driven in, and generally cut off flush with the end of the shaft. A Hirth joint is similar to a Spline joint but with the teeth on the butt of the shaft instead of on the surface.
Now I'm curious. I can see "scotch key" meaning "cheap-ass key" but I'm wondering where "dutch" comes from.

I believe 'dutch' might mean practical but workmanlike, alternative method. Once, I had double-hung window sills to replace that had decayed. Upper surface was OK, underside was splintered and ragged. A carpenter told me, make a "dutchman". Unstable pine wood was pared down to solid material by 4" power-saw, chisel and bullnose plane. Then replaced with poplar, then contours were shaped and painted like original. A little tedious working upside down, back in 1981. They are still in place, indistinguishable from original.
I'm not Scottish, but know a few...they are not the stereotypical cheap, they just get a lot of bang for the buck. And unlike some cultures, their products are first rate. True cheapskates don't do that!
Browing firearms use this technique to lock screws into place, take a look at the original Browning A5 shotgun and you will see lots of them.
As mentioned, not the strongest lock, but more than adequate on the shotguns.
