Why do climbers use these?

One of our most used bolts and we haven't made a video about them yet??? Bobby and I finally talked about all the tests we've done and updated the Bolting Bible with the concrete screws chapter. There is a lot of mystery about these things in the bolting community because there is no "rating" for climbing but they are awesome... for some situations. https://www.hownot2.com/post/bolting-...
