Grocery bike, it could hit about 20lbs, per side.
I'm not sure what pictures you're looking at, but part of the issue here is that nothing but Silly Putty will fit flush with the bottom eyelet of this fork.
And with at least 7mm between the eyelet and where a rack flange would be, this is not a good idea with most any material used to make M5 bolts.
