Perfect for what I’m doing

Ok, I guess. Pretty thin material.
Ok, I guess. Pretty thin material. Bends easily. Don't buy for Wedi installs.

These are great
These are great and way better than the plastic washer deal but be careful. They will stick you if you don’t watch. They hold great and tight on foam board insulation.

Fastening foam board to wood, awesome!
These worked great for attaching my 2" foam insulation boards to wood, using screws according to depth of course. Sheetrock screws worked fine.I built a carport, just threw 2" foam boards I got from a friend, on top for the roof and fastened the board's to the wood. Then covered the boards with a tarp that was leftover from a metal frame carport. The tarp outlasted the frame (hence, why I built the wood one with treated 4x4's) Now the wind won't mess up the foam boards. The roof is tight!I wanted a tin or poly corrugated roof, but this worked slick and was 1/4 of the cost.
