But mainly the bloke that cobbles the adverts together has only a modest grasp of our language, and no access to relevant technical dictionaries, or the time to look stuff up. So, he looks for something similar and that will do.

It’s not quite clear, Tim … but if by “the bloke that cobbles the adverts together” you mean tony4cats

May I suggest that you have a look at his non-ebay website: **LINK**

I have a Sandvik 50mm face/shell mill which takes four plain triangular inserts.
It's similar to this one on eBay, but a size smaller, and mine has the inserts facing the right way; I think they are now obsolete.

Each insert is held by a wedge into a shaped backing pad; the wedges themselves are retained and clamped by these double ended left/right screws; in my case quite small and using an M2.5 Allen key.
The wedge itself is threaded internally.

I struggled to find a suitable description on Sandvik's website, but these are similar to the items, though maybe the wrong sizes.

Sumitomo also seem to call them Differential Screws, at least in the MSC catalog anyway

Thanks, Bill … we’re definitely getting there.

One thing that shouts to me is that the price being asked by Mr English is very modest indeed.

Now … if only I had a design for something useful that needed them
