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
Attachment 222036
I would really like to get hold of a couple of the larger ones - any ideas where I can source these?

Cheers

Blacks Fasteners are where I’ve sourced mine in the past.

I had looked there but they don't have any in 10/32 (UNF) thread size just metric and a few in BSW thread sizes. Thanks anyway.
