- 5 Piece Powers bolts are popular among climbers. We talk about the pros and cons with 40 tests to back it up. All of that data will be found in the book of numbers of the bolting bible. www.hownot2.com/post/bolting-...

Sharing secrets and giving away stoke
for the algorithm gods... got to the end of 40 brake tests ;)
mfw I need a doctorate in petrology to recklessly risk my life dangling on a string in the middle of nowhere.
We've been successful removing 5 piece bolts with a 9mm tap to thread the 3/8 sleeve about 5 threads. Then you can pull the sleeve with your favorite puller with a 9mm adapter.
I’ve put hundreds of expanding sleeve bolts in for construction purposes, very cool to see how they interact with the rock or concrete. Thanks for putting in the effort
Great video. Thank you for bringing up proper spacing of any expansion type Bolt. I'm a structural designer for many types of buildings and one of the biggest mistakes that we see is not spacing expansion bolts properly. With a 2 3/4" Hilti kwik bolt I always make sure to space them at least 6" apart. 8 would be better. and no closer to the edge of a concrete slab than 3"
I tune in to see what Bobby's hair is doing today
Don't think I'll ever bolt anything, but it sure helps me evaluate the routes I'm climbing from a safety perspective 😊
I am one of the industrial users, can confirm, we don’t read the packaging either. Have had to replace plenty of zinc plated concrete anchors. Blown holes are the worst, occasionally get lucky using a larger anchor, but usually have to make a steel plate that the item bolts to, then has at least the depth of the hole x2 away new anchor spots.
watched to the end, commenting to prove engagement
As someone who doesn't, and won't, climb I'm always so amused that I enjoy these videos anyway.
Watched to the end and loved every minute of it! Thanks for all the work on this stuff guys!
I started climbing in Yosemite in the early 70s. The bolts we didn't hesitate to clip into with hardly a thought would rightfully appall you. Me too, looking back and after watching you guys the last few years.
This is why I love the internet. The depth you chaps go to is commendable!
Thank You for providing such good info on your videos.
The break tests were fascinating -all 40 of them! And that visual of the way the force is distributed through the rock was also excellent.
BEST Video! Fast moving, lots of info, and, as usual, very entertaining!!! Thanks guys!
I've followed the channel for a while now and have to say that you are going an excellent work with these videos! Even for a Finnish person you're not coming across as over confident. I love the way you're explaining your setups and caveats with the testing
Love picking up little bits of info I can crossover to different things like hiking, camping and 4 wheeling. Thanks for sharing and all that goes into everything.
I don't even climb and i watched to the end. you guys do 2 of my favorite things, break stuff and collect data and i am here for it.
