Is this 400 Stainless Steel? Bolt Busters

Nothing quite as productive as testing hangers that no longer exist! Rumor has it that climbtech made a 400 series stainless steel hanger instead of 304 or 316 like many stainless hangers are made of. They are magnetic and supposedly break without stretching as much as a other stainless. They discountinued it but it was a discussion found on Mountain Project at These were donated by Greg Barnes from the ASCA

Climbtech’s hangers (don’t use zinc plated outside)

We found the 22kn mbs hangers to be just as strong as the 25kn hangers. And they both broke like taffy.

➜➜➜400ss with 22kn MBS hangers broke at 36+, 36.48kn and 36.38kn

➜➜➜304ss with 25kn MBS hangers broke at 34.68kn, 37.10kn and 37.82kn

Breaking Gear Fear

Edutainment has been a great way to help people understand their gear, and know the true limitations of it.  Watching HOW gear fails is more important than the force itself, as almost all gear is super good enough.  It's more important to share information on how to stay safe than it is to have a paywall.  We hope our stoke is contagious.
