two of my wifes snap studs or what ever you call them fell out.
looking on ebay theres differences sizes.
so bought a set turned out to small.
how do you measure these studs.??
its the male one that we need.
I went through similar recently when I pulled some out of a pair of overalls. I first bought a cheap box full from Lidl, but none were any good for the thick fabric..
My understanding is that male part is called the post, and the bit that pokes into it and mushrooms over is called the eyelet. Some manufactures / sites will list dimensions, so you may be able to find a post diameter and height that matches what you need.
If you have a measurement, will see whether anything in the Lidl box looks suitable?
