I have used that.
I tightened the retainer and put just a little in each hole where earlier drilled. I used Loctite 222 which is weak.
Another rear hub nothing, copper paste only to let it move easier
Threads had issues after the removal of old retainer since I punched rather hard in the beginning of the 80s with no thoughts about a remote future where I have to replace bearings again. Maybe parked for 20 years helped. Quality SKF bearings
That bearing is squeezed into it place when wheel is tightened.
