Well I think the screw thread size is M3.5 but not sure about head size. Still looking for a bigger head. The standard M3.5 head is to small for these inserts.

The holder that Shars sells takes a 4.0mm x10 Torx screw. This pages lists the screw as a replacement item: https://www.shars.com/5-8-x-4-1-2-rh-srgcr-indexable-tool-holder-for-rckt-insert I bought a toolholder from Aliexpress that takes this insert, they probably list replacement screws, as I have bought packages of various screws for my other toolholders from them. Lots cheaper.
