They are very good quality items and mean yo unever loose a drive pin!
I use them on some of my cars but not all, on the ones I don't I put a blob of a good thread lock into the groove in the hex and then fit it and let it go off over night. The hex never moves but a quick tap and it pops off.
Make sure it doesn't go in the bearings though.
That said I am about ot convert them all to the LAW30 as I think the extra security of the screw is useful for a clot like me
