Stainless Steel Snap Set, Marine Grade, 80 Piece

Would these work with the Sailrite pres-n-snap tool with the standard dies? Thx

The snaps i buy from west marine do not last on my marine cushions and canvas. are these heavy duty? they also have to thread through thick fabric.

Can i replace a snap on a seat strap that goes through four layers of nagahyde (vinyl) then the other end is screwed to the back of the seat

I wonder if you could use screws with both halves to fasten a lightweight wooden panel in place and make it removable?
