Couple of equivalents and the spec for  GCr105

But could just as easily be General Chinese Recycled

Coming at it from a different direction, I know you can buy individual balls for bearings that use balls as their rolling elements.

Can you find a sutable individual roller for a bearing that uses rollers as its rolling elements?

You may find – from a decent bearing shop – that there are needle-rollers – available loose, for peanuts, lots of sizes – which would serve your purpose.

Try Boneham and Turner they supply dowels in any size plain tapped and are these are all hardened and ground. They use a steel which is case hardened to at least 0.030″ deep withe a tough core. This makes sure that there is minimum wear and not brittle if they were through hardened as the steel core hardens to a tough hardness.

And in 2024, the imperial specification ones still have BA and BSF internal threads. BS 1804-1, made in 1966, still going strong.

Does anyone know a UK source (or even the US Standard number) for imperial dowel pins with UN threads?

Michael, they must have a different price for people living in Wales. On my interweb it says 3mm *23.8mm rounded end £4.49 for a pack of 10. Plus vat +post of course, which will bump the price up. I can give you a piece of 3mm silver steel, but you’d have to harden and temper it.

That’s showing flat end, my price was round end. Do you need flat end? If you do then next length up round end is £7.79 for 10, carefully grind the ends off
