Second recommendation for Team Tough. Their customer service is excellent as well. Another option is Fixe. While their customer service is no where near the same level as team tough Fixe makes good hangers and the prices on thier website are reasonable but you can ussually find better prices on mechanical anchors with a few minutes on google.

I tend to find the best deals for expansion anchors on construction supply websites. You don't get the added markup that climbing specific retailers add. Just make sure you are buying quality SS hardware with ICC-ES ratings. For hangers, look for a climbing specific retailer that is running a sale. Fixe's website sometimes has package deals for hangers.
I'd consider those redheads plenty strong enough. Others would look for a stronger bolt. It helps that they are ICC-ES rated. That's what I use in Utah limestone.
Usually what I do is take the SKU for the bolt I'm interested in (like the above-mentioned redheads), and Google search it. You can often find deals on random websites.
Just looked at UIAA standard for mechanical bolts and the only strength specification is 20kN in tension. I was thinking there were minimums for both tension and shear loading, although I may be confusing EN standards with UIAA. Anybody know what, if any, EN standards are for bolts used in climbing? Is 25kN in tension and 20kN shear good?

Yeah I've stopped purchasing regular hangers because Jim's rod hangers are so much better, although I still have a bunch of petzl hangers from pro deal. And for what it's worth, I don't think twist bolts would get to 50kN in my rock. The rock would probably explode before the bolt broke or pulled.
I would think 20kN would be enough, as that's the standard for carabiners, although runners are 22kN minimum. Still, does anybody know what the standard is for sheer strength?
