One is for use indoors, one is good for all-around conditions. Say you are building a structure in a humid environment or outside, then you would want to invest in stainless. If this is your typical garage/basement set up, then you'll be just fine getting the zinc.

My understanding (and I'm no expert) is that zinc plating is as the name suggests steel with a thin zinc plate. the zinc stops the metal rusting, however its easily scratched and if it does get scratched moisture gets through to the steel underneath and can start to rust it. Stainless steal itself is rust resistant and it does not matter if the surface becomes scratched.

Stainless t-nuts seem like a waste of money unless you get stainless bolts to go with them.

They might get a tiny bit of surface rust but they will never get bad enough that it is a problem.

Hi mendou, For your applications zinc plated t-nuts should be just fine. Stainless steel comes in many different grades and is far more difficult to manufacture than plain old steel with zinc plating. High quality stainless steel which we sell is called austenitic. This type of SS is combined with Chromium and up to 7% Nickel and is highly resistant to corrosion. Ferritic stainless steel which does not stand up to corrosion as well, and is much cheaper has less nickel in it. Nickel prices right now are extremely high since there isn't a whole lot of it to go around. Long story short: Cost of Manufacturing + Cost of Nickel = Expensive Stainless Steel. Send us an email or give us a call anytime if you have more questions! threeballclimbing@yahoo.com 480-334-4646 Keep up with Three Ball Climbing on Facebook! http://www.facebook.com/..._Climbing/1491042551
