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.

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.

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.

The foundation pins were worth using. They were sturdy and after three months are still holding the crawl space together. They were also easy to install.

These were very easy to use! We used very little caulking with these for an extra seal. The videos were great help. Answered all our questions and were very useful over all. We couldn't have done this easy DIY project without them. We highly recommend these products. It took us a total of 12 hours spread over 3 days to complete our small crawl space, including clean out and leveling of dirt. And we're 55! Fast delivery, too. Our total cost was 1/5 of each of the 2 bids we received from basement experts.
