I'm not sure how you plan to use them with a climber unless you are going to use the climber to install them. I've done that before. The only screw-in steps I've used are the Ameristeps they sell at WallyWorld. The best advise I can give you is to get a step installer. It takes about 80% of the work out of installing them. Take a bar of soap with you as well and lube the threads up, that helps a bunch. Be safe.
