Help! Snap-in Boat Carpet

I have boat with snap-in carpet and a few of the snaps are missing from the floor. (They are screwed into a fiberglass floor.)
Does anyone know where I might buy some of those?

Go to Amazon, type in:

"snap stud screw"

in the search feature. Should give you a whole boatload of options (pun intended )

If you wanted to buy in a box store, probably West Marine will be your best bet.

Dangit, I just ordered stuff from Amazon a few days ago. Wish I had thought to check on these!

Thanks a bunch for the tip
