Oooooooooooooooh Rick, you got sum 'splainin ta do...

I like this kind of testing and find it cool, but what does it really tell use, besides that glue-ins are strong as shit, regardless of the kind?

How do 5 piece bolts do with the same testing?

Thanks for the testing rick, looks like fun!

okay...i just pulled up the testing data again and the fixe bolt data is gone.

i bet fixe goons made him pull it with a threat of legal action if he didn't for some kind of defamation of their product.

rick, you don't have to go into detail, but if they threatened you...i think we should know so i know which letters to write and which companies to avoid.

No threats. Removed data irrelevant to glue-in bolt testing - the subject of the post.

i see what you are saying. i don't believe it's necessarily irrelevant due to the fact that the good ol standard 5 piece is what most of us are used to and a good frame of reference, but i get you.

The strength of a newly placed plated 5-piece setup in good rock is fairly irrelevant relative to their poor durability & susceptibility to corrosion. Plated hangers are a particularly bad choice in the Red.

In the construction industry where this type of epoxy is utilized the most, they typically claim a 20 year life expectancy on the epoxy but you won't find this printed anywhere. To remove the epoxy anchors you just have to heat up the bolt and twist. I think they are great in most applications. They still scare me in a roof since gravity would work against the installer and the big dig tragedy as an example. Most engineers will only use epoxy anchors that are in a shear mode and not so much in tension.

Good observation.

One of the lessons learned from this incident: Make sure you understand the basics of potential polymer failure, such as susceptibility to creep under long-term tensile loads. However, glue-in bolts used in a climbing route application are not "susceptible to creep under long-term tensile loads" because they are simply not under long-term tensile loads. Rather, they are loaded only occasionally. 99+ percent of their lives, they are under no load, hence very little creep.

Have you ever completed a test on the different adhesives, Mr. Weber? I'd be interested in seeing which glues hold the best using the same bolt. It would be nice to see if the quick set glues hold just as well as the glues that take a day or so to set up.

Epcon A7 is quick-setup epoxy relative to Hilti RE500. The tests used both.
