Senco SPFN15XP 15 Gauge Composite Finish Nailer, 1/2" to 1-1/2" #9H0001N

I use it on my CNC machine to hold the parts down. Nails wood to the 3/4 inch MDF spoil board on the machine. It holds just as good as the metal screws I've been using. To get it to release you knock the board you nailed down sideways with a hammer and it snaps the plastic nails off clean. you have to look hard to see where they were. Also, it doesn't pull up on the spoil board when done like the metal screws did so that's less surface leveling I would need to do. If the router bit hits the nail it just cuts it like it was part of the wood so it won't damage the bit. I also tried it on aluminum flashing and it did great. Testing to see if I could get the flashing off the board and the flashing tore. Not the plastic nail head. One thing; the nail head sticks up like a 1 millimeter or so. Looks to be the way it's supposed to be but still works for me. You can knock that nail head off if you like but I think it adds to the strength.
