They work great, i wish they made some longer though so you can fit them through the foam insulation as well.

These pins go hand in hand with the foundation tape. Really easy to drill in to your walls and pound these pins in. Luckily I didn't have any concrete block to drill into, but with wood its super easy.

These pins are great! They have decrease our installation time by 15 to 20 percent.

The pins worked exactly as described and made a tricky job much easier. The large heads made it easy to hit the mark, as well as being a large surface to better secure the vapor barrier. The quality and design was very good and the price was much less than a tapcon. This was my first crawl space experience (hopefully my last), but the products purchased were perfect and the tech support was professional, courteous, very helpful.

The pins are very strong and durable.
