Thread: Source for10/32 t-nuts

I am looking for some 10/32 t-nuts to put a front sling stud on a carbon stock. I have got some but the flange diameter on these are 1/2" versus the 3/4 inch ones that I have in one of my other stocks - see photo below

I would really like to get hold of a couple of the larger ones - any ideas where I can source these?

Cheers
