They work as described and you will definitely need them to hold the vapor barrier in place. Don't rely on 60 Foundation Seal Tape alone.

These pins are easy to work with. Just by using a 1/4" drill bit to create the need hole, I could literally push the pin in with my thumb. It took no time at all to finish the perimeter of my crawl space.

Pins worked very well and held tight w a 1/4" bit. Tap them in slowly to get them seated and then a few good hits will set them nicely. Used most of the bag and all worked very well. The longer length if these is preferable to others out there. Recommended for DIY installs and pros. Must admit there was a certain amount of satisfaction driving these little things in place. I used twice as many as needed, and even more on a wall that nothing would stick to. Am really happy with the results.

Just wanted to leave a comment for anyone on the fence about getting this product. Don't hesitate- it's totally worth it. Shipping is super fast and everything is exceptional quality.

Just used them and seemed to work fine. Easy install.
